ANNEX I ADMINISTRATIVE PROVISIONS FOR EC TYPE-APPROVAL

1. ADDITIONAL REQUIREMENTS FOR GRANTING OF EC TYPE-APPROVAL

1.1. Additional requirements for mono fuel gas vehicles, bi-fuel gas vehicles and flex fuel H2NG vehicles.
1.1.1. For the purposes of section 1.1 the following definitions shall apply:
1.1.1.1. A family means a group of vehicle types fuelled by LPG, NG/biomethane, H2NG, identified by a parent vehicle.
1.1.1.2. A parent vehicle means a vehicle that is selected to act as the vehicle on which the self adaptability of a fuelling system is going to be demonstrated, and to which the members of a family refer. It is possible to have more than one parent vehicle in a family.
1.1.1.3. A member of the family means a vehicle that shares the following essential characteristics with its parent:
(a) It is produced by the same vehicle manufacturer;
(b) It is subject to the same emission limits;
(c) If the gas fuelling system has a central metering for the whole engine, it has a certified power output between 0,7 and 1,15 times that of the engine of the parent vehicle;
(d) If the gas fuelling system has an individual metering per cylinder, it has a certified power output per cylinder between 0,7 and 1,15 times that of the engine of the parent vehicle;
(e) If fitted with a catalyst system, it has the same type of catalyst i.e. three-way, oxidation, de NOx;
(f) It has a gas fuelling system (including the pressure regulator) from the same system manufacturer and of the same type: induction, vapour injection (single point, multipoint), liquid injection (single point, multipoint);
(g) This gas fuelling system is controlled by an ECU of the same type and technical specification, containing the same software principles and control strategy. The vehicle may have a second ECU compared to the parent vehicle, provided that the ECU is only used to control the injectors, additional shut-off valves and the data acquisition from additional sensors.
With regard to the requirements referred to in point (c) and (d), in the case where a demonstration shows two gas fuelled vehicles could be members of the same family with the exception of their certified power output, respectively P1 and P2 (P1 < P2), and both are tested as if they were parent vehicles, the family relation will be considered valid for any vehicle with a certified power output between 0,7 × P1 and 1,15 × P2.
1.1.2. In case of vehicles fuelled by LPG, NG/biomethane, H2NG, EC type-approval is granted subject to the following requirements:
1.1.2.1. For the type-approval of a parent vehicle, the parent vehicle shall demonstrate its capability to adapt to any fuel composition that may occur across the market. In the case of LPG there are variations in C3/C4 composition. In the case of natural gas there are generally two types of fuel, high calorific fuel (H-gas) and low calorific fuel (L-gas), but with a significant spread within both ranges; they differ significantly in Wobbe index. These variations are reflected in the reference fuels.
In the case of a flex fuel H2NG vehicle, the composition range may vary from 0 % hydrogen to a maximum percentage of hydrogen within the mixture, which shall be specified by the manufacturer. The parent vehicle shall demonstrate its capability to adapt to any percentage, within the range specified by the manufacturer. It shall also demonstrate its capability to adapt to any NG/biomethane composition that may occur across the market, regardless of the percentage of hydrogen in the mixture.
1.1.2.2. In the case of vehicles fuelled by LPG, NG/biomethane, the parent vehicle shall be tested in the type 1 test on the two extreme gas reference fuels set out in Annex IX. In the case of NG/biomethane, if the transition from one gas fuel to the other gas fuel is, in practice, aided through the use of a switch, this switch shall not be used during type-approval.
In the case of flex fuel H2NG vehicles, the parent vehicle shall be tested in the type 1 test with the following fuel compositions:
100 % H-gas.
100 % L-gas.
The mixture of H-gas and the maximum percentage of hydrogen specified by the manufacturer.
The mixture of L-gas and the maximum percentage of hydrogen specified by the manufacturer.
1.1.2.3. The vehicle is considered to conform if, under the tests and reference fuels mentioned in point 1.1.2.2, the vehicle complies with the emission limits.
1.1.2.4. In the case of vehicles fuelled by LPG or NG/biomethane, the ratio of emission results ‘ r ’ shall be determined for each pollutant as follows:
Type of fuel	Reference fuels	Calculation of ‘r’
LPG	fuel A	r=BA
	fuel B	
NG/Biomethane	fuel G20	r=G25G20
	fuel G25	
1.1.2.5. In the case of flex fuel H2NG vehicles, two ratios of emission results ‘r 1 ’ and ‘r 2 ’, shall be determined for each pollutant as follows:
Type of fuel	Reference fuels	Calculation of ‘r’
NG/biomethane	fuel G20	r1=G25G20
	fuel G25	
H2NG	Mixture of hydrogen and G20 with the maximum percentage of hydrogen specified by the manufacturer	r2=H2G25H2G20
	Mixture of hydrogen and G25 with the maximum percentage of hydrogen specified by the manufacturer	
1.1.3. For the type-approval of a mono- fuel gas vehicle and bi-fuel gas vehicles operating in gas mode, fuelled by LPG or NG/biomethane, as a member of the family, a type 1 test shall be performed with one gas reference fuel. This reference fuel may be either of the gas reference fuels. The vehicle is considered to comply if the following requirements are met:
(a) the vehicle complies with the definition of a family member as defined in section 1.1.1.3;
(b) if the test fuel is the reference fuel A for LPG or G20 for NG/Biomethane, the emission result for each pollutant shall be multiplied by the relevant factor ‘r’ calculated in section 1.1.2.4 if r > 1; if r < 1, no correction is needed;
(c) if the test fuel is the reference fuel B for LPG or G25 for NG/Biomethane, the emission result for each pollutant shall be divided by the relevant factor ‘r’ calculated in section 1.1.2.4 if r < 1; if r > 1, no correction is needed;
(d) on the manufacturer’s request the type 1 test may be performed on both reference fuels, so that no correction is needed;
(e) the vehicle shall comply with the emission limits valid for the relevant category for both measured and calculated emissions;
(f) if repeated tests are made on the same engine the results on reference fuel G20, or A, and those on reference fuel G25, or B, shall first be averaged; the ‘r’ factor shall then be calculated from these averaged results;
(g) during the type 1 test the vehicle shall only use petrol for a maximum of 60 seconds when operating in gas mode.
1.1.4. For the type-approval of a flex fuel H2NG vehicle as a member of a family, two type 1 tests shall be performed, the first test with 100 % of either G20 or G25, and the second test with the mixture of hydrogen and the same NG/biomethane fuel used during the first test, with the maximum hydrogen percentage specified by the manufacturer.
The vehicle tested in accordance with the first paragraph shall be considered as complying if, in addition to requirements set out in points (a), (e) and (g) of point 1.1.3., the following requirements are met:
(a) if the NG/biomethane fuel is the reference fuel G20, the emission result for each pollutant shall be multiplied by the relevant factors (r 1 for the first test and r 2 for the second test), calculated in section 1.1.2.5, if the relevant factor > 1; if the correspondent relevant factor < 1, no correction is needed;
(b) if the NG/biomethane fuel is the reference fuel G25, the emission result for each pollutant shall be divided by the correspondent relevant factor (r 1 for the first test and r 2 for the second test) calculated in accordance with point 1.1.2.5, if the correspondent relevant factor < 1; if the correspondent relevant factor > 1, no correction is needed;
(c) on the manufacturer's request the type 1 test must be performed with the four possible combinations of reference fuels, according to section 1.1.2.5, so that no correction is needed;
(d) if repeated tests are made on the same engine the results on reference fuel G20, or H2G20, and those on reference fuel G25, or H2G25 with the maximum hydrogen percentage specified by the manufacturer, shall first be averaged; the ‘r 1 ’ and ‘r 2 ’ factors shall then be calculated from these averaged results.

1.2. Additional requirements for flex fuel vehicles
1.2.1. For the type-approval of a flex fuel ethanol or biodiesel vehicle, the vehicle manufacturer shall describe the capability of the vehicle to adapt to any mixture of petrol and ethanol fuel (up to an 85 % ethanol blend) or diesel and biodiesel that may occur across the market.

Explanatory note :
The dates of application of the reference fuels E10 and B7 for all new vehicles have been set out to minimise the test burden. If, however, technical evidence for vehicles certified with E5 or B5 reference fuels showing significantly higher emissions when tested with E10 or B7 is established, the Commission should make a proposal advancing these introduction dates.

4.2.2.3. The production of a series shall be deemed to conform or not to conform on the basis of a sampling test of the vehicles once a pass decision is reached for all the pollutants or a fail decision is reached for one pollutant, according to the test criteria applied in the appropriate appendix.
When a pass decision has been reached for one pollutant, that decision shall not be changed by any additional tests carried out to reach a decision for the other pollutants.
If no pass decision is reached for all the pollutants and no fail decision is reached for one pollutant, a test shall be carried out on another vehicle (see Figure I.4.2).

4.3.4.3. The provisions of Section 4.2.3.2 shall be replaced by the following:
If the manufacturer wishes to run in the vehicles, (‘x’ km, where x ≤ 15 000 km), the procedure shall be the following:
(a) the pollutant emissions shall be measured at zero and at ‘x’ km on the first tested vehicle;
(b) the evolution coefficient of the emissions between zero and ‘x’ km shall be calculated for each of the pollutant:
Emissions ‘x’ km/Emissions zero km
This may be less than 1; and
(c) the other vehicles shall not be run in, but their zero km emissions shall be multiplied by the evolution coefficient. In this case, the values to be taken shall be:

The average of in-use-performance ratios IUPR M of all selected vehicles for each monitor according to points 3.1.4 and 3.1.5 of Appendix 1 to Annex XI,
The percentage of selected vehicles, which have an IUPR M greater or equal to the minimum value applicable to the monitor according to points 3.1.4 and 3.1.5 of Appendix 1 to Annex XI.

3. SELECTION OF VEHICLES FOR IN-SERVICE CONFORMITY
3.1. The information gathered by the manufacturer shall be sufficiently comprehensive to ensure that in-service performance can be assessed for normal conditions of use. The manufacturer’s sampling shall be drawn from at least two Member States with substantially different vehicle operating conditions (unless only sold in one Member State). Factors such as differences in fuels, ambient conditions, average road speeds, and urban/highway driving split shall be taken into consideration in the selection of the Member States.
For OBD IUPR M testing only vehicles fulfilling the criteria of point 2.2.1 of Appendix 1 shall be included in the test sample.
3.2. In selecting the Member States for sampling vehicles, the manufacturer may select vehicles from a Member State that is considered to be particularly representative. In this case, the manufacturer shall demonstrate to the approval authority which granted the type approval that the selection is representative (e.g. by the market having the largest annual sales of a vehicle family within the Union). When a family requires more than one sample lot to be tested as defined in point 3.5, the vehicles in the second and third sample lots shall reflect different vehicle operating conditions from those selected for the first sample.
3.3. The emissions testing may be done at a test facility which is located in a different market or region from where the vehicles have been selected.
3.4. The in-service tailpipe emissions conformity tests by the manufacturer shall be continuously carried out reflecting the production cycle of applicable vehicles types within a given in-service vehicle family. The maximum time period between commencing two in-service conformity checks shall not exceed 18 months. In the case of vehicle types covered by an extension to the type-approval that did not require an emissions test, this period may be extended up to 24 months.

3.5. Sample size

3.5.1. When applying the statistical procedure defined in Appendix 2 (i.e. for tailpipe emissions), the number of sample lots shall depend on the annual sales volume of an in-service family in the Union, as defined in the following table:
EU Registrationsper calendar year (for tailpipe emission tests),of vehicles of an OBD family with IUPR in the sampling period	Number of sample lots
up to 100 000	1
100 001 to 200 000	2
above 200 000	3

3.5.2. For IUPR, the number of sample lots to be taken is described in the table in point 3.5.1 and is based on the number of vehicles of an OBD family that are approved with IUPR (subject to sampling).
For the first sampling period of an OBD family, all of the vehicle types in the family that are approved with IUPR shall be considered to be subject to sampling. For subsequent sampling periods, only vehicle types which have not been previously tested or are covered by emissions approvals that have been extended since the previous sampling period shall be considered to be subject to sampling.
For families consisting of fewer than 5 000 EU registrations that are subject to sampling within the sampling period the minimum number of vehicles in a sample lot is six. For all other families, the minimum number of vehicles in a sample lot to be sampled is fifteen.
Each sample lot shall adequately represent the sales pattern, i.e. at least high volume vehicle types (≥ 20 % of the family total) shall be represented.
4. On the basis of the audit referred to in Section 2 the approval authority shall adopt one of the following decisions and actions:
(a) decide that the in-service conformity of a vehicle type, vehicle in-service family or vehicle OBD family is satisfactory and not take any further action;
(b) decide that the data provided by the manufacturer is insufficient to reach a decision and request additional information or test data from the manufacturer;
(c) decide that based on data from the approval authority or Member State surveillance testing programmes, that information provided by the manufacturer is insufficient to reach a decision and request additional information or test data from the manufacturer;
(d) decide that the in-service conformity of a vehicle type, that is part of an in-service family, or of an OBD family, is unsatisfactory and proceed to have such vehicle type or OBD family tested in accordance with Appendix 1.
If according to the IUPR M audit the test criteria of point 6.1.2 point (a) or (b) of Appendix 1 are met for the vehicles in a sample lot, the type-approval authority must take the further action described in point (d) of this point.
4.1. Where type 1 tests are considered necessary to check the conformity of emission control devices with the requirements for their performance while in service, such tests shall be carried out using a test procedure meeting the statistical criteria defined in Appendix 2.
4.2. The approval authority, in cooperation with the manufacturer, shall select a sample of vehicles with sufficient mileage whose use under normal conditions can be reasonably assured. The manufacturer shall be consulted on the choice of the vehicles in the sample and allowed to attend the confirmatory checks of the vehicles.
4.3. The manufacturer shall be authorised, under the supervision of the approval authority, to carry out checks, even of a destructive nature, on those vehicles with emission levels in excess of the limit values with a view to establishing possible causes of deterioration which cannot be attributed to the manufacturer (e.g. use of leaded petrol before the test date). Where the results of the checks confirm such causes, those test results shall be excluded from the conformity check.
Appendix 1

In-service conformity check

1. INTRODUCTION
1.1. This Appendix sets out the criteria referred to in Section 4 regarding the selection of vehicles for testing and the procedures for the in-service conformity control.

2. SELECTION CRITERIA
The criteria for acceptance of a selected vehicle are defined for tailpipe emissions in points 2.1 to 2.8 and for IUPR M in Sections 2.1 to 2.5.
2.1. The vehicle shall belong to a vehicle type that is type-approved under this Regulation and covered by a certificate of conformity in accordance with Directive 2007/46/EC. For checking of IUPR M , the vehicle shall be approved to the OBD standards Euro 5+, Euro 6- plus IUPR or later. It shall be registered and have been used in the Union.
2.2. The vehicle shall have been in service for at least 15 000 km or 6 months, whichever the later, and for no more than 100 000 km or 5 years, whichever the sooner.

2.2.1. For checking IUPR M , the test sample shall include only vehicles that:
(a) have collected sufficient vehicle operation data for the monitor to be tested.
For monitors required to meet the in-use monitor performance ratio and to track and report ratio data pursuant to point 3.6.1 of Appendix 1 to Annex XI, sufficient vehicle operation data shall mean the denominator meets the criteria set forth below. The denominator, as defined in points 3.3 and 3.5 of Appendix 1 to Annex XI, for the monitor to be tested must have a value equal to or greater than one of the following values:
(i) 75 for evaporative system monitors, secondary air system monitors, and monitors utilising a denominator incremented in accordance with point 3.3.2 points (a), (b) or (c) of Appendix 1 to Annex XI (e.g. cold start monitors, air conditioning system monitors, etc.); or
(ii) 25 for particulate filter monitors and oxidation catalyst monitors utilising a denominator incremented in accordance with point 3.3.2(d) of Appendix 1 to Annex XI; or
(iii) 150 for catalyst, oxygen sensor, EGR, VVT, and all other component monitors;
(b) have not been tampered with or equipped with add-on or modified parts that would cause the OBD system not to comply with the requirements of Annex XI.
2.3. There shall be a maintenance record to show that the vehicle has been properly maintained (e.g. has been serviced in accordance with the manufacturer’s recommendations).
2.4. The vehicle shall exhibit no indications of abuse (e. g. racing, overloading, mis-fuelling, or other misuse), or other factors (e. g. tampering) that could affect emission performance. The fault code and mileage information stored in the computer shall be taken into account. A vehicle shall not be selected for testing if the information stored in the computer shows that the vehicle has operated after a fault code was stored and a relatively prompt repair was not carried out.
2.5. There shall have been no unauthorised major repair to the engine or major repair of the vehicle.
2.6. The lead content and sulphur content of a fuel sample from the vehicle tank shall meet the applicable standards laid down in Directive 98/70/EC of the European Parliament and of the Council and there shall be no evidence of mis-fuelling. Checks may be done in the tailpipe.
OJ L 350, 28.12.1998, p. 58 .
2.7. There shall be no indication of any problem that might jeopardise the safety of laboratory personnel.
2.8. All anti-pollution system components on the vehicle shall be in conformity with the applicable type-approval.

3. DIAGNOSIS AND MAINTENANCE

3. GENERAL REQUIREMENTS

3.1. PEMS
The test shall be carried out with a PEMS, composed of components specified in points 3.1.1 to 3.1.5. If applicable, a connection with the vehicle ECU may be established to determine relevant engine and vehicle parameters as specified in point 3.2.
3.1.1. Analysers to determine the concentration of pollutants in the exhaust gas.

3.2. Test parameters
Test parameters as specified in Table 1 of this Annex shall be measured, recorded at a constant frequency of 1,0 Hz or higher and reported according to the requirements of Appendix 8. If ECU parameters are obtained, these should be made available at a substantially higher frequency than the parameters recorded by PEMS to ensure correct sampling.

Notes:		

3.3. Preparation of the vehicle
The preparation of the vehicle shall include a general technical and operational check.

3.4. Installation of PEMS

3.4.1. General
The installation of the PEMS shall follow the instructions of the PEMS manufacturer and the local health and safety regulations. The PEMS should be installed as to minimise during the test electromagnetic interferences as well as exposure to shocks, vibration, dust and variability in temperature. The installation and operation of the PEMS shall be leak-tight and minimise heat loss. The installation and operation of PEMS shall not change the nature of the exhaust gas nor unduly increase the length of the tailpipe. To avoid the generation of particles, connectors shall be thermally stable at the exhaust gas temperatures expected during the test. It is recommended not to use elastomer connectors to connect the vehicle exhaust outlet and the connecting tube. Elastomer connectors, if used, shall have a minimum exposure to the exhaust gas to avoid artefacts at high engine load.

3.4.2. Permissible backpressure
The installation and operation of the PEMS shall not unduly increase the static pressure at the exhaust outlet. If technically feasible, any extension to facilitate the sampling or connection with the exhaust mass flow meter shall have an equivalent, or larger, cross-sectional area as the exhaust pipe.

3.4.3. Exhaust mass flow meter
Whenever used, the exhaust mass flow meter shall be attached to the vehicle's tailpipe(s) according to the recommendations of the EFM manufacturer. The measurement range of the EFM shall match the range of the exhaust mass flow rate expected during the test. The installation of the EFM and any exhaust pipe adaptors or junctions shall not adversely affect the operation of the engine or exhaust after-treatment system. A minimum of four pipe diameters or 150 mm of straight tubing, whichever is larger, shall be placed either side of the flow-sensing element. When testing a multi-cylinder engine with a branched exhaust manifold, it is recommended to combine the manifolds upstream of the exhaust mass flow meter and to increase the cross section of the piping appropriately as to minimise backpressure in the exhaust. If this is not feasible, exhaust flow measurements with several exhaust mass flow meters shall be considered. The wide variety of exhaust pipe configurations, dimensions and expected exhaust mass flow rates may require compromises, guided by good engineering judgement, when selecting and installing the EFM(s). If measurement accuracy requires, it is permissible to install an EFM with a diameter smaller than that of the exhaust outlet or the total cross-sectional area of multiple outlets, providing it does not adversely affect the operation or the exhaust after-treatment as specified in point 3.4.2.

3.4.4. Global Positioning System
The GPS antenna should be mounted, e.g. at the highest possible location, as to ensure good reception of the satellite signal. The mounted GPS antenna shall interfere as little as possible with the vehicle operation.

3.4.5. Connection with the Engine Control Unit
If desired, relevant vehicle and engine parameters listed in Table 1 can be recorded by using a data logger connected with the ECU or the vehicle network following standards, e.g. ISO 15031-5 or SAE J1979, OBD-II, EOBD or WWH-OBD. If applicable, manufacturers shall disclose parameter labels to allow the identification of required parameters.

3.4.6. Sensors and auxiliary equipment
Vehicle speed sensors, temperature sensors, coolant thermocouples or any other measurement device not part of the vehicle shall be installed to measure the parameter under consideration in a representative, reliable and accurate manner without unduly interfering with the vehicle operation and the functioning of other analysers, flow-measuring instruments, sensors and signals. Sensors and auxiliary equipment shall be powered independently of the vehicle.
It is permitted to power any safety-related illumination of fixtures and installations of PEMS components outside of the vehicle's cabin by the vehicle's battery.

3.5. Emissions sampling
Emissions sampling shall be representative and conducted at locations of well-mixed exhaust where the influence of ambient air downstream of the sampling point is minimal. If applicable, emissions shall be sampled downstream of the exhaust mass flow meter, respecting a distance of at least 150 mm to the flow sensing element. The sampling probes shall be fitted at least 200 mm or three times the diameter of the exhaust pipe, whichever is larger, upstream of the vehicle's exit of the exhaust outlet, which is the point at which the exhaust exits the PEMS sampling installation into the environment. If the PEMS feeds back a flow to the tail pipe, this shall occur downstream of the sampling probe in a manner that does not affect during engine operation the nature of the exhaust gas at the sampling point(s). If the length of the sample line is changed, the system transport times shall be verified and if necessary corrected.
If the engine is equipped with an exhaust after-treatment system, the exhaust sample shall be taken downstream of the exhaust after-treatment system. When testing a vehicle with a multi-cylinder engine and branched exhaust manifold, the inlet of the sampling probe shall be located sufficiently far downstream so as to ensure that the sample is representative of the average exhaust emissions of all cylinders. In multi-cylinder engines, having distinct groups of manifolds, such as in a ‘ V ’ engine configuration, the manifolds shall be combined upstream of the sampling probe. If this is technically not feasible, multi-point sampling at locations of well-mixed exhaust free of ambient air shall be considered. In this case, the number and location of sampling probes shall match as far as possible that of the exhaust mass flow meters. In case of unequal exhaust flows, proportional sampling or sampling with multiple analysers shall be considered.
If particles are measured, the exhaust shall be sampled from the centre of the exhaust stream. If several probes are used for emissions sampling, the particle sampling probe shall be placed upstream of the other sampling probes.
If hydrocarbons are measured, the sampling line shall be heated to 463 ± 10 K (190 ± 10 °C). For the measurement of other gaseous components with or without cooler, the sampling line shall be kept at a minimum of 333 K (60 °C) as to avoid condensation and to ensure appropriate penetration efficiencies of the various gases. For low pressure sampling systems, the temperature can be lowered corresponding to the pressure decrease provided that the sampling system ensures a penetration efficiency of 95 % for all regulated gaseous pollutants. If particles are sampled, the sampling line from the raw exhaust sample point shall be heated to a minimum of 373 K (100 °C). The residence time of the sample in the particle sampling line shall be less than 3 s until reaching first dilution or the particle counter.

4. PRE-TEST PROCEDURES

4.1. PEMS leak check
After the installation of PEMS is completed, a leak check shall be performed at least once for each PEMS-vehicle installation as prescribed by the PEMS manufacturer or as follows. The probe shall be disconnected from the exhaust system and the end plugged. The analyser pump shall be switched on. After an initial stabilisation period all flow meters shall read approximately zero in the absence of a leak. Else, the sampling lines shall be checked and the fault corrected.
The leakage rate on the vacuum side shall not exceed 0,5 per cent of the in-use flow rate for the portion of the system being checked. The analyser flows and bypass flows may be used to estimate the in-use flow rates.
Alternatively, the system may be evacuated to a pressure of at least 20 kPa vacuum (80 kPa absolute). After an initial stabilisation period the pressure increase Dp (kPa/min) in the system shall not exceed:
Δp=peVs×qvs×0,005
Alternatively, a concentration step change at the beginning of the sampling line shall be introduced by switching from zero to span gas while maintaining the same pressure conditions as under normal system operation. If for a correctly calibrated analyser after an adequate period of time the reading is ≤ 99 per cent compared to the introduced concentration, the leakage problem shall be corrected.

4.2. Starting and stabilising the PEMS
The PEMS shall be switched on, warmed up and stabilised according to the specifications of the PEMS manufacturer until, e.g. pressures, temperatures and flows have reached their operating set points.

4.3. Preparing the sampling system
The sampling system, consisting of the sampling probe, sampling lines and the analysers, shall be prepared for testing by following the instruction of the PEMS manufacturer. It shall be ensured that the sampling system is clean and free of moisture condensation.

4.4. Preparing the EFM
If used for measuring the exhaust mass flow, the EFM shall be purged and prepared for operation in accordance with the specifications of the EFM manufacturer. This procedure shall, if applicable, remove condensation and deposits from the lines and the associated measurement ports.

4.5. Checking and calibrating the analysers for measuring gaseous emissions
Zero and span calibration adjustments of the analysers shall be performed using calibration gases that meet the requirements of point 5 of Appendix 2. The calibration gases shall be chosen to match the range of pollutant concentrations expected during the emissions test.
To minimise analyser drift, one should conduct the zero and span calibration of analysers at an ambient temperature that resembles, as closely as possible, the temperature experienced by the test equipment during the RDE trip.

4.6. Checking the analyser for measuring particle emissions
The zero level of the analyser shall be recorded by sampling HEPA filtered ambient air. The signal shall be recorded at a constant frequency of at least 1,0 Hz over a period of 2 min and averaged; the permissible concentration value shall be determined once suitable measurement equipment becomes available.

4.7. Measuring vehicle speed
Vehicle speed shall be determined by at least one of the following methods:
(a) a GPS; if vehicle speed is determined by a GPS, the total trip distance shall be checked against the measurements of another method according to point 7 of Appendix 4,
(b) a sensor (e.g. optical or micro-wave sensor); if vehicle speed is determined by a sensor, the speed measurements shall comply with the requirements of point 8 of Appendix 2, or alternatively, the total trip distance determined by the sensor shall be compared with a reference distance obtained from a digital road network or topographic map. The total trip distance determined by the sensor shall deviate by no more than 4 % from the reference distance,
(c) the ECU; if vehicle speed is determined by the ECU, the total trip distance shall be validated according to point 3 of Appendix 3 and the ECU speed signal adjusted, if necessary to fulfil the requirements of point 3.3 of Appendix 3. Alternatively, the total trip distance as determined by the ECU shall be compared with a reference distance obtained from a digital road network or topographic map. The total trip distance determined by the ECU shall deviate by no more than 4 % from the reference.

4.8. Check of PEMS set-up
The correctness of connections with all sensors and, if applicable, the ECU shall be verified. If engine parameters are retrieved, it shall be ensured that the ECU reports values correctly (e.g. zero engine speed (rpm) while the combustion engine is in key-on-engine-off status). The PEMS shall function free of warning signals and error indication.

5. EMISSIONS TEST

5.1. Test start
Sampling, measurement and recording of parameters shall begin prior to the start of the engine. To facilitate time alignment, it is recommended to record the parameters that are subject to time alignment either by a single data recording device or with a synchronised time stamp. Before as well as directly after engine start, it shall be confirmed that all necessary parameters are recorded by the data logger.

5.2. Test
Sampling, measurement and recording of parameters shall continue throughout the on-road test of the vehicle. The engine may be stopped and started, but emissions sampling and parameter recording shall continue. Any warning signals, suggesting malfunctioning of the PEMS, shall be documented and verified. Parameter recording shall reach a data completeness of higher than 99 %. Measurement and data recording may be interrupted for less than 1 % of the total trip duration but for no more than a consecutive period of 30 s solely in the case of unintended signal loss or for the purpose of PEMS system maintenance. Interruptions may be recorded directly by the PEMS but it is not permissible to introduce interruptions in the recorded parameter via the pre-processing, exchange or post-processing of data. If conducted, auto zeroing shall be performed against a traceable zero standard similar to the one used to zero the analyser. It is strongly recommended to initiate PEMS system maintenance during periods of zero vehicle speed.

5.3. Test end
The end of the test is reached when the vehicle has completed the trip and the combustion engine is switched off. The data recording shall continue until the response time of the sampling systems has elapsed.

6. POST-TEST PROCEDURE

6.1. Checking the analysers for measuring gaseous emissions
The zero and span of the analysers of gaseous components shall be checked by using calibration gases identical to the ones applied under point 4.5 to evaluate the analyser response drift compared to the pre-test calibration. It is permissible to zero the analyser prior to verifying the span drift, if the zero drift was determined to be within the permissible range. The post-test drift check shall be completed as soon as possible after the test and before the PEMS, or individual analysers or sensors, are turned off or have switched into a non-operating mode. The difference between the pre-test and post-test results shall comply with the requirements specified in Table 2.

Table 2

CO 2	≤ 2 000 ppm per test	≤ 2 % of reading or ≤ 2 000 ppm per test, whichever is larger
CO	≤ 75 ppm per test	≤ 2 % of reading or ≤ 75 ppm per test, whichever is larger

THC	≤ 10 ppmC 1 per test	≤ 2 % of reading or ≤ 10 ppmC 1 per test, whichever is larger
If the difference between the pre-test and post-test results for the zero and span drift is higher than permitted, all test results shall be voided and the test repeated.

6.2. Checking the analyser for measuring particle emissions
The zero level of the analyser shall be recorded by sampling HEPA filtered ambient air. The signal shall be recorded over a period of 2 min and averaged; the permissible final concentration shall be defined once suitable measurement equipment becomes available. If the difference between the pre-test and post-test zero and span check is higher than permitted, all test results shall be voided and the test repeated.

6.3. Checking the on-road emission measurements
The calibrated range of the analysers shall account at least for 90 % of the concentration values obtained from 99 % of the measurements of the valid parts of the emissions test. It is permissible that 1 % of the total number of measurements used for evaluation exceeds the calibrated range of the analysers by up to a factor of two. If these requirements are not met, the test shall be voided.

3. LINEARITY VERIFICATION

3.1. General

3.2. Linearity requirements
All analysers, flow-measuring instruments, sensors and signals shall comply with the linearity requirements given in Table 1. If air flow, fuel flow, the air-to-fuel ratio or the exhaust mass flow rate is obtained from the ECU, the calculated exhaust mass flow rate shall meet the linearity requirements specified in Table 1.

3.3. Frequency of linearity verification
The linearity requirements according to point 3.2 shall be verified:
(a) for each analyser at least every three months or whenever a system repair or change is made that could influence the calibration;
(b) for other relevant instruments, such as exhaust mass flow meters and traceably calibrated sensors, whenever damage is observed, as required by internal audit procedures, by the instrument manufacturer or by ISO 9000 but no longer than one year before the actual test.
The linearity requirements according to point 3.2 for sensors or ECU signals that are not directly traceable shall be performed once for each PEMS set-up with a traceably calibrated measurement device on the chassis dynamometer.

3.4. Procedure of linearity verification

3.4.1. General requirements
The relevant analysers, instruments and sensors shall be brought to their normal operating condition according to the recommendations of their manufacturer. The analysers, instruments and sensors shall be operated at their specified temperatures, pressures and flows.

3.4.2. General procedure
The linearity shall be verified for each normal operating range by executing the following steps:
(a) The analyser, flow-measuring instrument or sensor shall be set at zero by introducing a zero signal. For gas analysers, purified synthetic air or nitrogen shall be introduced to the analyser port via a gas path that is as direct and short as possible.
(b) The analyser, flow-measuring instrument or sensor shall be spanned by introducing a span signal. For gas analysers, an appropriate span gas shall be introduced to the analyser port via a gas path that is as direct and short as possible.
(c) The zero procedure of (a) shall be repeated.
(d) The verification shall be established by introducing at least 10, approximately equally spaced and valid, reference values (including zero). The reference values with respect to the concentration of components, the exhaust mass flow rate or any other relevant parameter shall be chosen to match the range of values expected during the emissions test. For measurements of exhaust mass flow, reference points below 5 % of the maximum calibration value can be excluded from the linearity verification.
(e) For gas analysers, known gas concentrations in accordance with point 5 shall be introduced to the analyser port. Sufficient time for signal stabilisation shall be given.
(f) The values under evaluation and, if needed, the reference values shall be recorded at a constant frequency of at least 1,0 Hz over a period of 30 seconds.
(g) The arithmetic mean values over the 30-second period shall be used to calculate the least squares linear regression parameters, with the best-fit equation having the form:
y = a 1 x + a 0
where:

y
is the actual value of the measurement system

a 1
is the slope of the regression line

x
is the reference value

a 0
is the y intercept of the regression line
The standard error of estimate (SEE) of y on x and the coefficient of determination (r 2 ) shall be calculated for each measurement parameter and system.
(h) The linear regression parameters shall meet the requirements specified in Table 1.

3.4.3. Requirements for linearity verification on a chassis dynamometer
Non-traceable flow-measuring instruments, sensors or ECU signals that cannot directly be calibrated according to traceable standards, shall be calibrated on the chassis dynamometer. The procedure shall follow as far as applicable, the requirements of Annex 4a to UN/ECE Regulation No 83. If necessary, the instrument or sensor to be calibrated shall be installed on the test vehicle and operated according to the requirements of Appendix 1. The calibration procedure shall follow whenever possible the requirements of point 3.4.2; at least 10 appropriate reference values shall be selected as to ensure that at least 90 % of the maximum value expected to occur during the emissions test is covered.
If a not directly traceable flow-measuring instrument, sensor or ECU signal for determining exhaust flow is to be calibrated, a traceably calibrated reference exhaust mass flow meter or the CVS shall be attached to the vehicle's tailpipe. It shall be ensured that the vehicle exhaust is accurately measured by the exhaust mass flow meter according to point 3.4.3 of Appendix 1. The vehicle shall be operated by applying constant throttle at a constant gear selection and chassis dynamometer load.

4. ANALYSERS FOR MEASURING GASEOUS COMPONENTS

4.1. Permissible types of analysers

4.1.1. Standard analysers
The gaseous components shall be measured with analysers specified in points 1.3.1 to 1.3.5 of Appendix 3, Annex 4A to UN/ECE Regulation No 83, 07 series of amendments. If an NDUV analyser measures both NO and NO 2 , a NO 2 /NO converter is not required.

4.1.2. Alternative analysers
Any analyser not meeting the design specifications of point 4.1.1 is permissible provided that it fulfils the requirements of point 4.2. The manufacturer shall ensure that the alternative analyser achieves an equivalent or higher measurement performance compared to a standard analyser over the range of pollutant concentrations and co-existing gases that can be expected from vehicles operated with permissible fuels under moderate and extended conditions of valid on-road testing as specified in points 5, 6 and 7. Upon request, the manufacturer of the analyser shall submit in writing supplemental information, demonstrating that the measurement performance of the alternative analyser is consistently and reliably in line with the measurement performance of standard analysers. Supplemental information shall contain:
(a) a description of the theoretical basis and the technical components of the alternative analyser;
(b) a demonstration of equivalency with the respective standard analyser specified in point 4.1.1 over the expected range of pollutant concentrations and ambient conditions of the type-approval test defined in Annex 4a to UN/ECE Regulation No 83, 07 series of amendments as well as a validation test as described in point 3 of Appendix 3 for a vehicle equipped with a spark-ignition and compression-ignition engine; the manufacturer of the analyser shall demonstrate the significance of equivalency within the permissible tolerances given in point 3.3 of Appendix 3;
(c) a demonstration of equivalency with the respective standard analyser specified in point 4.1.1 with respect to the influence of atmospheric pressure on the measurement performance of the analyser; the demonstration test shall determine the response to span gas having a concentration within the analyser range to check the influence of atmospheric pressure under moderate and extended altitude conditions defined in point 5.2. Such a test can be performed in an altitude environmental test chamber;
(d) a demonstration of equivalency with the respective standard analyser specified in point 4.1.1 over at least three on-road tests that fulfil the requirements of this Annex;
(e) a demonstration that the influence of vibrations, accelerations and ambient temperature on the analyser reading does not exceed the noise requirements for analysers set out in point 4.2.4.
Approval authorities may request additional information to substantiate equivalency or refuse approval if measurements demonstrate that an alternative analyser is not equivalent to a standard analyser.

4.2. Analyser specifications

4.2.1. General
In addition to the linearity requirements defined for each analyser in point 3, the compliance of analyser types with the specifications laid down in points 4.2.2 to 4.2.8 shall be demonstrated by the analyser manufacturer. Analysers shall have a measuring range and response time appropriate to measure with adequate accuracy the concentrations of the exhaust gas components at the applicable emissions standard under transient and steady state conditions. The sensitivity of the analysers to shocks, vibration, aging, variability in temperature and air pressure as well as electromagnetic interferences and other impacts related to vehicle and analyser operation shall be limited as far as possible.

4.2.2. Accuracy
The accuracy, defined as the deviation of the analyser reading from the reference value, shall not exceed 2 % of reading or 0,3 % of full scale, whichever is larger.

4.2.3. Precision
The precision, defined as 2,5 times the standard deviation of 10 repetitive responses to a given calibration or span gas, shall be no greater than 1 % of the full scale concentration for a measurement range equal or above 155 ppm (or ppmC 1 ) and 2 % of the full scale concentration for a measurement range of below 155 ppm (or ppmC 1 ).

4.2.4. Noise
The noise, defined as two times the root mean square of ten standard deviations, each calculated from the zero responses measured at a constant recording frequency of at least 1,0 Hz during a period of 30 seconds, shall not exceed 2 % of full scale. Each of the 10 measurement periods shall be interspersed with an interval of 30 seconds in which the analyser is exposed to an appropriate span gas. Before each sampling period and before each span period, sufficient time shall be given to purge the analyser and the sampling lines.

4.2.5. Zero response drift
The drift of the zero response, defined as the mean response to a zero gas during a time interval of at least 30 seconds, shall comply with the specifications given in Table 2.

4.2.6. Span response drift
The drift of the span response, defined as the mean response to a span gas during a time interval of at least 30 seconds, shall comply with the specifications given in Table 2.

Table 2
Permissible zero and span response drift of analysers for measuring gaseous components under laboratory conditions
Pollutant	Zero response drift	Span response drift
CO 2	≤ 1 000 ppm over 4 h	≤ 2 % of reading or ≤ 1 000 ppm over 4 h, whichever is larger
CO	≤ 50 ppm over 4 h	≤ 2 % of reading or ≤ 50 ppm over 4 h, whichever is larger
NO 2	≤ 5 ppm over 4 h	≤ 2 % of reading or ≤ 5 ppm over 4 h, whichever is larger

THC	≤ 10 ppmC 1	≤ 2 % of reading or ≤ 10 ppmC 1 over 4 h, whichever is larger

4.2.7. Rise time
Rise time is defined as the time between the 10 per cent and 90 per cent response of the final reading ( t 90 – t 10 ; see point 4.4). The rise time of PEMS analysers shall not exceed 3 seconds.

4.2.8. Gas drying
Exhaust gases may be measured wet or dry. A gas-drying device, if used, shall have a minimal effect on the composition of the measured gases. Chemical dryers are not permitted.

4.3. Additional requirements

4.3.1. General
The provisions in points 4.3.2 to 4.3.5 define additional performance requirements for specific analyser types and apply only to cases, in which the analyser under consideration is used for PEMS emission measurements.

4.3.2. Efficiency test for NO X converters
If a NO X converter is applied, for example to convert NO 2 into NO for analysis with a chemiluminescence analyser, its efficiency shall be tested by following the requirements of point 2.4 of Appendix 3 of Annex 4a to UN/ECE Regulation No 83, 07 series of amendments. The efficiency of the NO X converter shall be verified no longer than one month before the emissions test.

4.3.3. Adjustment of the Flame Ionisation Detector

(a) Optimisation of the detector response
If hydrocarbons are measured, the FID shall be adjusted at intervals specified by the analyser manufacturer by following point 2.3.1 of Appendix 3 of Annex 4a to UN/ECE Regulation No 83, 07 series of amendments. A propane-in-air or propane-in-nitrogen span gas shall be used to optimise the response in the most common operating range.

(b) Hydrocarbon response factors
If hydrocarbons are measured, the hydrocarbon response factor of the FID shall be verified by following the provisions of point 2.3.3 of Appendix 3 of Annex 4a to UN/ECE Regulation No 83, 07 series of amendments, using propane-in-air or propane-in-nitrogen as span gases and purified synthetic air or nitrogen as zero gases, respectively.

(c) Oxygen interference check
The oxygen interference check shall be performed when introducing an analyser into service and after major maintenance intervals. A measuring range shall be chosen in which the oxygen interference check gases fall in the upper 50 per cent. The test shall be conducted with the oven temperature set as required. The specifications of the oxygen interference check gases are described in point 5.3.
The following procedure applies:
(i) The analyser shall be set at zero.
(ii) The analyser shall be spanned with a 0 per cent oxygen blend for positive ignition engines and a 21 per cent oxygen blend for compression ignition engines.
(iii) The zero response shall be rechecked. If it has changed by more than 0,5 per cent of full scale, steps (i) and (ii) shall be repeated.
(iv) The 5 per cent and 10 per cent oxygen interference check gases shall be introduced.
(v) The zero response shall be rechecked. If it has changed by more than ± 1 per cent of full scale, the test shall be repeated.
(vi) The oxygen interference E O2 shall be calculated for each oxygen interference check gas in step (d) as follows:
EO2=cref,d−ccref,d×100
where the analyser response is:
c=cref,d×cFS,bcm,b×cm,bcFS,d
where:

c ref,b
is the reference HC concentration in step (b) [ppmC 1 ]

c ref,d
is the reference HC concentration in step (d) [ppmC 1 ]

c FS,b
is the full scale HC concentration in step (b) [ppmC 1 ]

c FS,d
is the full scale HC concentration in step (d) [ppmC 1 ]

c m,b
is the measured HC concentration in step (b) [ppmC 1 ]

c m,d
is the measured HC concentration in step (d) [ppmC 1 ].
(vii) The oxygen interference E O2 shall be less than ± 1,5 per cent for all required oxygen interference check gases.
(viii) If the oxygen interference E O2 is greater than ± 1,5 per cent, corrective action may be taken by incrementally adjusting the air flow (above and below the manufacturer's specifications), the fuel flow and the sample flow.
(ix) The oxygen interference check shall be repeated for each new setting.

4.3.4. Conversion efficiency of the non-methane cutter (NMC)
If hydrocarbons are analysed, a NMC can be used to remove non-methane hydrocarbons from the gas sample by oxidising all hydrocarbons except methane. Ideally, the conversion for methane is 0 per cent and for the other hydrocarbons represented by ethane is 100 per cent. For the accurate measurement of NMHC, the two efficiencies shall be determined and used for the calculation of the NMHC emissions (see point 9.2 of Appendix 4). It is not necessary to determine the methane conversion efficiency in case the NMC-FID is calibrated according to method (b) in point 9.2 of Appendix 4 by passing the methane/air calibration gas through the NMC.
(a) Methane conversion efficiency
Methane calibration gas shall be flown through the FID with and without bypassing the NMC; the two concentrations shall be recorded. The methane efficiency shall be determined as:
EM=1−cHCw∕NMCcHCw∕oNMC
where:

c HC(w/NMC)
is the HC concentration with CH 4 flowing through the NMC [ppmC 1 ]

c HC(w/o NMC)
is the HC concentration with CH 4 bypassing the NMC [ppmC 1 ]
(b) Ethane conversion efficiency
Ethane calibration gas shall be flown through the FID with and without bypassing the NMC; the two concentrations shall be recorded. The ethane efficiency shall be determined as:
EE=1−cHCw∕NMCcHCw∕oNMC
where:

c HC(w/NMC)
is the HC concentration with C 2 H 6 flowing through the NMC [ppmC 1 ]

c HC(w/o NMC)
is the HC concentration with C 2 H 6 bypassing the NMC [ppmC 1 ]

4.3.5. Interference effects

(a) General
Other gases than the ones being analysed can affect the analyser reading. A check for interference effects and the correct functionality of analysers shall be performed by the analyser manufacturer prior to market introduction at least once for each type of analyser or device addressed in points (b) to (f).

(b) CO analyser interference check
Water and CO 2 can interfere with the measurements of the CO analyser. Therefore, a CO 2 span gas having a concentration of 80 to 100 per cent of full scale of the maximum operating range of the CO analyser used during the test shall be bubbled through water at room temperature and the analyser response recorded. The analyser response shall not be more than 2 per cent of the mean CO concentration expected during normal on-road testing or ± 50 ppm, whichever is larger. The interference check for H 2 O and CO 2 may be run as separate procedures. If the H 2 O and CO 2 levels used for the interference check are higher than the maximum levels expected during the test, each observed interference value shall be scaled down by multiplying the observed interference with the ratio of the maximum expected concentration value during the test and the actual concentration value used during this check. Separate interference checks with concentrations of H 2 O that are lower than the maximum concentration expected during the test may be run and the observed H 2 O interference shall be scaled up by multiplying the observed interference with the ratio of the maximum H 2 O concentration value expected during the test and the actual concentration value used during this check. The sum of the two scaled interference values shall meet the tolerance specified in this point.

(c) NO X analyser quench check
The two gases of concern for CLD and HCLD analysers are CO 2 and water vapour. The quench response to these gases is proportional to the gas concentrations. A test shall determine the quench at the highest concentrations expected during the test. If the CLD and HCLD analysers use quench compensation algorithms that utilise H 2 O or CO 2 measurement analysers or both, quench shall be evaluated with these analysers active and with the compensation algorithms applied.

(i) CO 2 quench check
A CO 2 span gas having a concentration of 80 to 100 per cent of the maximum operating range shall be passed through the NDIR analyser; the CO 2 value shall be recorded as A. The CO 2 span gas shall then be diluted by approximately 50 per cent with NO span gas and passed through the NDIR and CLD or HCLD; the CO 2 and NO values shall be recorded as B and C, respectively. The CO 2 gas flow shall then be shut off and only the NO span gas shall be passed through the CLD or HCLD; the NO value shall be recorded as D. The per cent quench shall be calculated as:
ECO2=1−C×AD×A−D×B×100
where:

A
is the undiluted CO 2 concentration measured with NDIR [%]

B
is the diluted CO 2 concentration measured with NDIR [%]

C
is the diluted NO concentration measured with the CLD or HCLD [ppm]

D
is the undiluted NO concentration measured with the CLD or HCLD [ppm].
Alternative methods of diluting and quantifying of CO 2 and NO span gas values such as dynamic mixing/blending are permitted upon approval of the approval authority.

(ii) Water quench check
This check applies to measurements of wet gas concentrations only. The calculation of water quench shall consider dilution of the NO span gas with water vapour and the scaling of the water vapour concentration in the gas mixture to concentration levels that are expected to occur during an emissions test. A NO span gas having a concentration of 80 per cent to 100 per cent of full scale of the normal operating range shall be passed through the CLD or HCLD; the NO value shall be recorded as D . The NO span gas shall then be bubbled through water at room temperature and passed through the CLD or HCLD; the NO value shall be recorded as C . The analyser's absolute operating pressure and the water temperature shall be determined and recorded as E and F, respectively. The mixture's saturation vapour pressure that corresponds to the water temperature of the bubbler F shall be determined and recorded as G . The water vapour concentration H [%] of the gas mixture shall be calculated as:
H=GE×100
The expected concentration of the diluted NO-water vapour span gas shall be recorded as D e after being calculated as:
De=D×1−H100
For diesel exhaust, the maximum concentration of water vapour in the exhaust gas (in per cent) expected during the test shall be recorded as H m after being estimated, under the assumption of a fuel H/C ratio of 1,8/1, from the maximum CO 2 concentration in the exhaust gas A as follows:
Hm=0,9×A
The per cent water quench shall be calculated as:
EH2O=De−CDe×HmH×100
where:

D e
is the expected diluted NO concentration [ppm]

C
is the measured diluted NO concentration [ppm]

H m
is the maximum water vapour concentration [%]

H
is the actual water vapour concentration [%].

(iii) Maximum allowable quench
The combined CO 2 and water quench shall not exceed 2 per cent of full scale.

(d) Quench check for NDUV analysers
Hydrocarbons and water can positively interfere with NDUV analysers by causing a response similar to that of NO X . The manufacturer of the NDUV analyser shall use the following procedure to verify that quench effects are limited:
(i) The analyser and chiller shall be set up by following the operating instructions of the manufacturer; adjustments should be made as to optimise the analyser and chiller performance.
(ii) A zero calibration and span calibration at concentration values expected during emissions testing shall be performed for the analyser.
(iii) A NO 2 calibration gas shall be selected that matches as far as possible the maximum NO 2 concentration expected during emissions testing.
(iv) The NO 2 calibration gas shall overflow at the gas sampling system's probe until the NO X response of the analyser has stabilised.
(v) The mean concentration of the stabilised NO X recordings over a period of 30 s shall be calculated and recorded as NO X,ref .
(vi) The flow of the NO 2 calibration gas shall be stopped and the sampling system saturated by overflowing with a dew point generator's output, set at a dew point of 50 °C. The dew point generator's output shall be sampled through the sampling system and chiller for at least 10 minutes until the chiller is expected to be removing a constant rate of water.
(vii) Upon completion of (iv), the sampling system shall again be overflown by the NO 2 calibration gas used to establish NO X,ref until the total NO X response has stabilised.
(viii) The mean concentration of the stabilised NO X recordings over a period of 30 s shall be calculated and recorded as NO X,m .
(ix) NO X,m shall be corrected to NO X,dry based upon the residual water vapour that passed through the chiller at the chiller's outlet temperature and pressure.
The calculated NO X,dry shall at least amount to 95 % of NO X,ref .

(e) Sample dryer
A sample dryer removes water, which can otherwise interfere with the NO X measurement. For dry CLD analysers, it shall be demonstrated that at the highest expected water vapour concentration H m the sample dryer maintains the CLD humidity at ≤ 5 g water/kg dry air (or about 0,8 per cent H 2 O), which is 100 per cent relative humidity at 3,9 °C and 101,3 kPa or about 25 per cent relative humidity at 25 °C and 101,3 kPa. Compliance may be demonstrated by measuring the temperature at the outlet of a thermal sample dryer or by measuring the humidity at a point just upstream of the CLD. The humidity of the CLD exhaust might also be measured as long as the only flow into the CLD is the flow from the sample dryer.

(f) Sample dryer NO 2 penetration
Liquid water remaining in an improperly designed sample dryer can remove NO 2 from the sample. If a sample dryer is used in combination with a NDUV analyser without an NO 2 /NO converter upstream, water could therefore remove NO 2 from the sample prior to the NO X measurement. The sample dryer shall allow for measuring at least 95 per cent of the NO 2 contained in a gas that is saturated with water vapour and consists of the maximum NO 2 concentration expected to occur during a vehicle test.

4.4. Response time check of the analytical system
For the response time check, the settings of the analytical system shall be exactly the same as during the emissions test (i.e. pressure, flow rates, filter settings in the analysers and all other parameters influencing the response time). The response time shall be determined with gas switching directly at the inlet of the sample probe. The gas switching shall be done in less than 0,1 second. The gases used for the test shall cause a concentration change of at least 60 per cent full scale of the analyser.
The concentration trace of each single gas component shall be recorded. The delay time is defined as the time from the gas switching ( t 0 ) until the response is 10 per cent of the final reading ( t 10 ). The rise time is defined as the time between 10 per cent and 90 per cent response of the final reading ( t 90 – t 10 ). The system response time ( t 90 ) consists of the delay time to the measuring detector and the rise time of the detector.
For time alignment of the analyser and exhaust flow signals, the transformation time is defined as the time from the change ( t 0 ) until the response is 50 per cent of the final reading ( t 50 ).
The system response time shall be ≤ 12 s with a rise time of ≤ 3 seconds for all components and all ranges used. When using a NMC for the measurement of NMHC, the system response time may exceed 12 seconds.

Pure and mixed calibration and span gases shall fulfil the specifications of points 3.1 and 3.2 of Appendix 3 of Annex 4A to UN/ECE Regulation No 83, 07 series of amendments. In addition, NO 2 calibration gas is permissible. The concentration of the NO 2 calibration gas shall be within two per cent of the declared concentration value. The amount of NO contained in NO 2 calibration gas shall not exceed 5 per cent of the NO 2 content.

The verification shall be performed at between 15 and 50 per cent of full scale for each calibration incorporating a gas divider. An additional verification may be performed using another calibration gas, if the first verification has failed.
Optionally, the gas divider may be checked with an instrument which by nature is linear, e.g. using NO gas in combination with a CLD. The span value of the instrument shall be adjusted with the span gas directly connected to the instrument. The gas divider shall be checked at the settings typically used and the nominal value shall be compared with the concentration measured by the instrument. The difference shall in each point be within ± 1 per cent of the nominal concentration value.

5.3. Oxygen interference check gases
Oxygen interference check gases consist of a blend of propane, oxygen and nitrogen and shall contain propane at a concentration of 350 ± 75 ppmC 1 . The concentration shall be determined by gravimetric methods, dynamic blending or the chromatographic analysis of total hydrocarbons plus impurities. The oxygen concentrations of the oxygen interference check gases shall meet the requirements listed in Table 3; the remainder of the oxygen interference check gas shall consist of purified nitrogen.

Table 3

7. INSTRUMENTS FOR MEASURING EXHAUST MASS FLOW

7.1. General
Instruments, sensors or signals for measuring the exhaust mass flow rate shall have a measuring range and response time appropriate for the accuracy required to measure the exhaust mass flow rate under transient and steady state conditions.

Each individual exhaust mass flow meter shall fulfil the linearity requirements set out in point 3. Furthermore, the instrument manufacturer shall demonstrate the compliance of each type of exhaust mass flow meter with the specifications in points 7.2.3 to 7.2.9.
It is permissible to calculate the exhaust mass flow rate based on air flow and fuel flow measurements obtained from traceably calibrated sensors if these fulfil the linearity requirements of point 3, the accuracy requirements of point 8 and if the resulting exhaust mass flow rate is validated according to point 4 of Appendix 3.
In addition, other methods that determine the exhaust mass flow rate based on not directly traceable instruments and signals, such as simplified exhaust mass flow meters or ECU signals are permissible if the resulting exhaust mass flow rate fulfils the linearity requirements of point 3 and is validated according to point 4 of Appendix 3.

7.2.1. Calibration and verification standards

Each of the 10 measurement periods shall be interspersed with an interval of 30 seconds in which the EFM is exposed to the maximum calibrated flow.

7.2.6. Zero response drift
Zero response is defined as the mean response to zero flow during a time interval of at least 30 seconds. The zero response drift can be verified based on the reported primary signals, e.g. pressure. The drift of the primary signals over a period of 4 hours shall be less than ± 2 per cent of the maximum value of the primary signal recorded at the flow at which the EFM was calibrated.

7.2.7. Span response drift
Span response is defined as the mean response to a span flow during a time interval of at least 30 seconds. The span response drift can be verified based on the reported primary signals, e.g. pressure. The drift of the primary signals over a period of 4 hours shall be less than ± 2 per cent of the maximum value of the primary signal recorded at the flow at which the EFM was calibrated.

7.2.8. Rise time
The rise time of the exhaust flow instruments and methods should match as far as possible the rise time of the gas analysers as specified in point 4.2.7 but shall not exceed 1 second.

7.2.9. Response time check
The response time of exhaust mass flow meters shall be determined by applying similar parameters as those applied for the emissions test (i.e. pressure, flow rates, filter settings and all other response time influences). The response time determination shall be done with gas switching directly at the inlet of the exhaust mass flow meter. The gas flow switching shall be done as fast as possible, but highly recommended in less than 0,1 second. The gas flow rate used for the test shall cause a flow rate change of at least 60 per cent full scale (FS) of the exhaust mass flow meter. The gas flow shall be recorded. The delay time is defined as the time from the gas flow switching ( t 0 ) until the response is 10 per cent ( t 10 ) of the final reading. The rise time is defined as the time between 10 per cent and 90 per cent response ( t 90 – t 10 ) of the final reading. The response time ( t 90 ) is defined as the sum of the delay time and the rise time. The exhaust mass flow meter response time ( t 90 ) shall be ≤ 3 seconds with a rise time ( t 90 – t 10 ) of ≤ 1 second in accordance with point 7.2.8.

8. SENSORS AND AUXILIARY EQUIPMENT

The accuracy of sensors and auxiliary equipment shall fulfil the requirements of Table 4. Compliance with the requirements of Table 4 shall be demonstrated at intervals specified by the instrument manufacturer, as required by internal audit procedures or in accordance with ISO 9000.

3. VALIDATION PROCEDURE FOR PEMS

3.1. Frequency of PEMS validation
It is recommended to validate the installed PEMS once for each PEMS-vehicle combination either before the test or, alternatively, after the completion of an on-road test. The PEMS installation shall be kept unchanged in the time period between the on-road test and the validation.

3.2. PEMS validation procedure

3.2.1. PEMS installation
The PEMS shall be installed and prepared according to the requirements of Appendix 1. After the completion of the validation test until the start of the on-road test, the PEMS installation shall not be changed.

3.2.2. Test conditions
The validation test shall be conducted on a chassis dynamometer, as far as applicable, under type-approval conditions by following the requirements of Annex 4a to UN/ECE Regulation No 83, 07 series of amendments or any other adequate measurement method. It is recommended to conduct the validation test with the worldwide harmonised light vehicles test cycle (WLTC) as specified in Annex 1 to UNECE Global Technical Regulation No 15. The ambient temperature shall be within the range specified in point 5.2 of this Annex.
It is recommended to feed the exhaust flow extracted by the PEMS during the validation test back to the CVS. If this is not feasible, the CVS results shall be corrected for the extracted exhaust mass. If the exhaust mass flow rate is validated with an exhaust mass flow meter, it is recommended to cross-check the mass flow rate measurements with data obtained from a sensor or the ECU.

3.2.3. Data analysis
The total distance-specific emissions [g/km] measured with laboratory equipment shall be calculated following Annex 4a to UN/ECE Regulation No 83, 07 series of amendments. The emissions as measured with the PEMS shall be calculated according to point 9 of Appendix 4, summed to give the total mass of pollutant emissions [g] and then divided by the test distance [km] as obtained from the chassis dynamometer. The total distance-specific mass of pollutants [g/km], as determined by the PEMS and the reference laboratory system, shall be compared and evaluated against the requirements specified in point 3.3. For the validation of NO X emission measurements, humidity correction shall be applied following point 6.6.5 of Annex 4a to UN/ECE Regulation No 83, 07 series of amendments.

3.3. Permissible tolerances for PEMS validation

4. VALIDATION PROCEDURE FOR THE EXHAUST MASS FLOW RATE DETERMINED BY NON-TRACEABLE INSTRUMENTS AND SENSORS

4.1. Frequency of validation
In addition to fulfilling the linearity requirements of point 3 of Appendix 2 under steady-state conditions, the linearity of non-traceable exhaust mass flow meters or the exhaust mass flow rate calculated from non-traceable sensors or ECU signals shall be validated under transient conditions for each test vehicle against a calibrated exhaust mass flow meter or the CVS. The validation test procedure can be executed without the installation of the PEMS but shall generally follow the requirements defined in Annex 4a to UN/ECE Regulation No 83, 07 series of amendments and the requirements pertinent to exhaust mass flow meters defined in Appendix 1.

4.2. Validation procedure
The validation test shall be conducted on a chassis dynamometer under type-approval conditions, as far as applicable, by following the requirements of Annex 4a to UN/ECE Regulation No 83, 07 series of amendments. The test cycle shall be the worldwide harmonised light vehicles test cycle (WLTC) as specified in Annex 1 to UNECE Global Technical Regulation No 15. As reference, a traceably calibrated flow meter shall be used. The ambient temperature can be any within the range specified in point 5.2 of this Annex. The installation of the exhaust mass flow meter and the execution of the test shall fulfil the requirement of point 3.4.3 of Appendix 1 of this Annex.
The following calculation steps shall be taken to validate the linearity:
(a) The signal under validation and the reference signal shall be time corrected by following, as far as applicable, the requirements of point 3 of Appendix 4.
(b) Points below 10 % of the maximum flow value shall be excluded from the further analysis.
(c) At a constant frequency of at least 1,0 Hz, the signal under validation and the reference signal shall be correlated using the best-fit equation having the form:
y = a 1 x + a 0
where:

y
is the actual value of the signal under validation

3. TIME CORRECTION OF PARAMETERS
For the correct calculation of distance-specific emissions, the recorded traces of component concentrations, exhaust mass flow rate, vehicle speed, and other vehicle data shall be time corrected. To facilitate the time correction, data which are subject to time alignment shall be recorded either in a single data recording device or with a synchronised timestamp following point 5.1 of Appendix 1. The time correction and alignment of parameters shall be carried out by following the sequence described in points 3.1 to 3.3.

3.1. Time correction of component concentrations
The recorded traces of all component concentrations shall be time corrected by reverse shifting according to the transformation times of the respective analysers. The transformation time of analysers shall be determined according to point 4.4 of Appendix 2:
c i,c (t – Δt t,i ) = c i,r (t)
where:

c i,c
is the time-corrected concentration of component i as function of time t

c i,r
is the raw concentration of component i as function of time t

Δt t,i
is the transformation time t of the analyser measuring component i.

3.2. Time correction of exhaust mass flow rate
The exhaust mass flow rate measured with an exhaust flow meter shall be time corrected by reverse shifting according to the transformation time of the exhaust mass flow meter. The transformation time of the mass flow meter shall be determined according to point 4.4.9 of Appendix 2:
q m,c (t – Δt t,m ) = q m ,r (t)
where:

q m,c
is the time-corrected exhaust mass flow rate as function of time t

q m,r
is the raw exhaust mass flow rate as function of time t

Δt t,m
is the transformation time t of the exhaust mass flow meter.
In case the exhaust mass flow rate is determined by ECU data or a sensor, an additional transformation time shall be considered and obtained by cross-correlation between the calculated exhaust mass flow rate and the exhaust mass flow rate measured following point 4 of Appendix 3.

3.3. Time alignment of vehicle data
Other data obtained from a sensor or the ECU shall be time-aligned by cross-correlation with suitable emission data (e.g. component concentrations).

3.3.1. Vehicle speed from different sources
To time align vehicle speed with the exhaust mass flow rate, it is first necessary to establish one valid speed trace. In case vehicle speed is obtained from multiple sources (e.g. the GPS, a sensor or the ECU), the speed values shall be time aligned by cross-correlation.

3.3.2. Vehicle speed with exhaust mass flow rate
Vehicle speed shall be time aligned with the exhaust mass flow rate by means of cross-correlation between the exhaust mass flow rate and the product of vehicle velocity and positive acceleration.

3.3.3. Further signals
The time alignment of signals whose values change slowly and within a small value range, e.g. ambient temperature, can be omitted.

4. COLD START
The cold start period covers the first 5 minutes after initial start of the combustion engine. If the coolant temperature can be reliably determined, the cold start period ends once the coolant has reached 343 K (70 °C) for the first time but no later than 5 minutes after initial engine start. Cold start emissions shall be recorded.

5. EMISSION MEASUREMENTS DURING ENGINE STOP
Any instantaneous emissions or exhaust flow measurements obtained while the combustion engine is deactivated shall be recorded. In a separate step, the recorded values shall afterward be set to zero by the data post processing. The combustion engine shall be considered as deactivated if two of the following criteria apply: the recorded engine speed is < 50 rpm; the exhaust mass flow rate is measured at < 3 kg/h; the measured exhaust mass flow rate drops to < 15 % of the steady-state exhaust mass flow rate at idling.

6. CONSISTENCY CHECK OF VEHICLE ALTITUDE
In case well-reasoned doubts exist that a trip has been conducted above of the permissible altitude as specified in point 5.2 of Annex IIIA and in case altitude has only been measured with a GPS, the GPS altitude data shall be checked for consistency and, if necessary, corrected. The consistency of data shall be checked by comparing the latitude, longitude and altitude data obtained from the GPS with the altitude indicated by a digital terrain model or a topographic map of suitable scale. Measurements that deviate by more than 40 m from altitude depicted in the topographic map shall be manually corrected and marked.

7. CONSISTENCY CHECK OF GPS VEHICLE SPEED
The vehicle speed as determined by the GPS shall be checked for consistency by calculating and comparing the total trip distance with reference measurements obtained from either a sensor, the validated ECU or, alternatively, from a digital road network or topographic map. It is mandatory to correct GPS data for obvious errors, e.g. by applying a dead reckoning sensor, prior to the consistency check. The original and uncorrected data file shall be retained and any corrected data shall be marked. The corrected data shall not exceed an uninterrupted time period of 120 s or a total of 300 s. The total trip distance as calculated from the corrected GPS data shall deviate by no more than 4 % from the reference. If the GPS data do not meet these requirements and no other reliable speed source is available, the test results shall be voided.

8. CORRECTION OF EMISSIONS

8.1. Dry-wet correction
If the emissions are measured on a dry basis, the measured concentrations shall be converted to a wet basis as:
c wet = k w · c dry
where:

c wet
is the wet concentration of a pollutant in ppm or per cent volume

c dry
is the dry concentration of a pollutant in ppm or per cent volume

k w
is the dry-wet correction factor
The following equation shall be used to calculate k w :
kw=11+α×0,005×cCO2+cCO×1,008
where:
kw1=1,608×Ha1000+1,608×Ha
where:

H a
is the intake air humidity [g water per kg dry air]

c CO2
is the dry CO 2 concentration [%]

c CO
is the dry CO concentration [%]

α
is the molar hydrogen ratio.

8.2. Correction of NOx for ambient humidity and temperature
NO x emissions shall not be corrected for ambient temperature and humidity.

9. DETERMINATION OF THE INSTANTANEOUS GASEOUS EXHAUST COMPONENTS

9.1. Introduction
The components in the raw exhaust gas shall be measured with the measurement and sampling analysers described in Appendix 2. The raw concentrations of relevant components shall be measured in accordance with Appendix 1. The data shall be time corrected and aligned in accordance with point 3.

9.2. Calculating NMHC and CH 4 concentrations
For methane measurement using a NMC-FID, the calculation of NMHC depends on the calibration gas/method used for the zero/span calibration adjustment. When a FID is used for THC measurement without a NMC, it shall be calibrated with propane/air or propane/N 2 in the normal manner. For the calibration of the FID in series with a NMC, the following methods are permitted:
(a) the calibration gas consisting of propane/air bypasses the NMC;
(b) the calibration gas consisting of methane/air passes through the NMC.
It is strongly recommended to calibrate the methane FID with methane/air through the NMC.
In method (a), the concentrations of CH 4 and NMHC shall be calculated as follows:
cCH4=cHCw∕oNMC×1−EM−cHCw∕NMCEE−EM
cNMHC=cHCw∕NMC−cHCw∕oNMC×1−EErh×EE−EM
In case (b), the concentration of CH 4 and NMHC shall be calculated as follows:
cHC4=cHCw∕NMC×rh×1−EM−cHCw∕oNMC×1−EErh×EE−EM
cNMHC=cHCw∕oNMC×1−EM−cHCw∕NMC×rh×1−EMEE−EM
where:

c HC(w/oNMC)
is the HC concentration with CH 4 or C 2 H 6 bypassing the NMC [ppmC 1 ]

c HC(w/NMC)
is the HC concentration with CH 4 or C 2 H 6 flowing through the NMC [ppmC 1 ]

r h

10. DETERMINATION OF EXHAUST MASS FLOW

10.1. Introduction
The calculation of instantaneous mass emissions according to points 11 and 12 requires determining the exhaust mass flow rate. The exhaust mass flow rate shall be determined by one of the direct measurement methods specified in point 7.2 of Appendix 2. Alternatively, it is permissible to calculate the exhaust mass flow rate as described in points 10.2 to 10.4.

10.2. Calculation method using air mass flow rate and fuel mass flow rate
The instantaneous exhaust mass flow rate can be calculated from the air mass flow rate and the fuel mass flow rate as follows:
q mew,i = q maw,i + q mf,i
where:

q m ew,i
is the instantaneous exhaust mass flow rate [kg/s]

q m aw,i
is the instantaneous intake air mass flow rate [kg/s]

q m f,i
is the instantaneous fuel mass flow rate [kg/s].
If the air mass flow rate and the fuel mass flow rate or the exhaust mass flow rate are determined from ECU recording, the calculated instantaneous exhaust mass flow rate shall meet the linearity requirements specified for the exhaust mass flow rate in point 3 of Appendix 2 and the validation requirements specified in point 4.3 of Appendix 3.

10.3. Calculation method using air mass flow and air-to-fuel ratio
The instantaneous exhaust mass flow rate can be calculated from the air mass flow rate and the air-to-fuel ratio as follows:
qmew,i=qmaw,i×1+1A∕Fst×λi
where:
A∕Fst=138,0×1+α4−ε2+γ12,011+1,008×α+15,9994×ε+14,0067×δ+32,0675×γ

where:

is the instantaneous intake air mass flow rate [kg/s]

A/F st
is the stoichiometric air-to-fuel ratio [kg/kg]

l i
is the instantaneous excess air ratio

β
is the molar carbon ratio (C/C)

γ
is the molar sulphur ratio (S/C)

δ
is the molar nitrogen ratio (N/C)

ε
is the molar oxygen ratio (O/C).
Coefficients refer to a fuel C β H α O ε N δ S γ with β = 1 for carbon-based fuels. The concentration of HC emissions is typically low and may be omitted when calculating l i .
If the air mass flow rate and air-to-fuel ratio are determined from ECU recording, the calculated instantaneous exhaust mass flow rate shall meet the linearity requirements specified for the exhaust mass flow rate in point 3 of Appendix 2 and the validation requirements specified in point 4.3 of Appendix 3.

10.4. Calculation method using fuel mass flow and air-to-fuel ratio
The instantaneous exhaust mass flow rate can be calculated from the fuel flow and the air-to-fuel ratio (calculated with A/F st and l i according to point 10.3) as follows:
q mew,i = q mf,i × (1 + A / F st × λ i )
The calculated instantaneous exhaust mass flow rate shall meet the linearity requirements specified for the exhaust gas mass flow rate in point 3 of Appendix 2 and the validation requirements specified in point 4.3 of Appendix 3.

11. CALCULATING THE INSTANTANEOUS MASS EMISSIONS
The instantaneous mass emissions [g/s] shall be determined by multiplying the instantaneous concentration of the pollutant under consideration [ppm] with the instantaneous exhaust mass flow rate [kg/s], both corrected and aligned for the transformation time, and the respective u value of Table 1. If measured on a dry basis, the dry-wet correction according to point 8.1 shall be applied to the instantaneous component concentrations before executing any further calculations. If applicable, negative instantaneous emission values shall enter all subsequent data evaluations. All significant digits of intermediate results shall enter the calculation of the instantaneous emissions. The following equation shall be applied:
m gas,i = u gas · c gas,i · q mew,i
where:

This section will define future requirements for calculating instantaneous particle number emissions, once their measurement becomes mandatory.

13. DATA REPORTING AND EXCHANGE
The data shall be exchanged between the measurement systems and the data evaluation software by a standardised reporting file as specified in point 2 of Appendix 8. Any pre-processing of data (e.g. time correction according to point 3 or the correction of the GPS vehicle speed signal according to point 7) shall be done with the control software of the measurement systems and shall be completed before the data reporting file is generated. If data are corrected or processed prior to entering the data reporting file, the original raw data shall be kept for quality assurance and control. Rounding of intermediate values is not permitted. Instead, intermediate values shall enter the calculation of instantaneous emissions [g/s; #/s] as reported by the analyser, flow-measuring instrument, sensor or the ECU.

Verification of trip dynamic conditions with method 1 (Moving Averaging Window)

1. INTRODUCTION
The Moving Averaging Window method provides an insight on the real-driving emissions (RDE) occurring during the test at a given scale. The test is divided in sub-sections (windows) and the subsequent statistical treatment aims at identifying which windows are suitable to assess the vehicle RDE performance.
The ‘normality’ of the windows is conducted by comparing their CO 2 distance-specific emissions with a reference curve. The test is complete when the test includes a sufficient number of normal windows, covering different speed areas (urban, rural, motorway).
For hybrids, the total energy consumption shall be converted to CO 2 . The rules for this conversion will be introduced in a second step.

3. MOVING AVERAGING WINDOWS

3.1. Definition of averaging windows
The instantaneous emissions calculated according to Appendix 4 shall be integrated using a moving averaging window method, based on the reference CO 2 mass. The principle of the calculation is as follows: the mass emissions are not calculated for the complete data set, but for sub-sets of the complete data set, the length of these sub-sets being determined so as to match the CO 2 mass emitted by the vehicle over the reference laboratory cycle. The moving average calculations are conducted with a time increment corresponding to the data sampling frequency. These sub-sets used to average the emissions data are referred to as ‘averaging windows’. The calculation described in the present point may be run from the last point (backwards) or from the first point (forward).
The following data shall not be considered for the calculation of the CO 2 mass, the emissions and the distance of the averaging windows:
the periodic verification of the instruments and/or after the zero drift verifications,
the cold start emissions, defined according to Appendix 4, point 4.4,
vehicle ground speed < 1 km/h,
any section of the test during which the combustion engine is switched off.
The mass (or particle number) emissions M gas,j shall be determined by integrating the instantaneous emissions in g/s (or #/s for PN) calculated as specified in Appendix 4.

Figure 1 Vehicle speed versus time — Vehicle averaged emissions versus time, starting from the first averaging window

Figure 2 Definition of CO 2 mass based averaging windows
The duration (t 2, j – t 1, j ) of the j th averaging window is determined by:

Where:
MCO2ti,j
is the CO 2 mass measured between the test start and time (t i,j ), [g];
MCO2,ref
is the half of the CO 2 mass [g] emitted by the vehicle over the WLTP cycle (Type I test, including cold start);
t 2, j shall be selected such as:
MCO2t2,j−Δt−MCO2t1,j<MCO2,ref≤MCO2t2,j−MCO2t1,j
Where Δ t is the data sampling period.
The CO 2 masses are calculated in the windows by integrating the instantaneous emissions calculated as specified in Appendix 4 to this Annex.

3.2. Calculation of window emissions and averages
The following shall be calculated for each window determined in accordance with point 3.1:
the distance-specific emissions M gas,d,j for all the pollutants specified in this annex,
the distance-specific CO 2 emissions M CO2,d,j ,
the average vehicle speed
v–j

4. EVALUATION OF WINDOWS

4.1. Introduction
The reference dynamic conditions of the test vehicle are set out from the vehicle CO 2 emissions versus average speed measured at type approval and referred to as ‘vehicle CO 2 characteristic curve’.
To obtain the distance-specific CO 2 emissions, the vehicle shall be tested using the road load settings prescribed in the UNECE Global Technical Regulation No 15 — worldwide harmonised light vehicles test procedure (ECE/TRANS/180/Add.15).

4.2. CO 2 characteristic curve reference points
The reference points P 1 , P 2 and P 3 required to define the curve shall be established as follows:

4.2.1. Point P 1
vP1–=19 km∕h
(average speed of the Low Speed phase of the WLTP cycle)
MCO2,d,P1
= Vehicle CO 2 emissions over the Low Speed phase of the WLTP cycle × 1,2 [g/km].

4.2.2. Point P 2
4.2.3. vP2–=56,6 km∕h
(average speed of the High Speed phase of the WLTP cycle)
MCO2,d,P2

4.2.4. Point P 3

(average speed of the Extra High Speed phase of the WLTP cycle)
MCO2,d,P3
= Vehicle CO 2 emissions over the Extra High Speed phase of the WLTP cycle × 1,05 [g/km]

4.3. CO 2 characteristic curve definition
Using the reference points defined in point 4.2, the characteristic curve CO 2 emissions are calculated as a function of the average speed using two linear sections ( P 1 , P 2 ) and ( P 2 , P 3 ). The section ( P 2 , P 3 ) is limited to 145 km/h on the vehicle speed axis. The characteristic curve is defined by equations as follows:
For the section ( P 1 , P 2 ):
MCO2,d,CCv–=a1v–+b1
with:
a1=MCO2,d,P2−MCO2,d,P1∕vP2–−vP1–
and:

For the section ( P 2 , P 3 ):
MCO2,d,CCv–=a2v–+b2

5.2. Verification of test completeness
The test shall be complete when it comprises at least 15 % of urban, rural and motorway windows, out of the total number of windows.

5.3. Verification of test normality
The test shall be normal when at least 50 % of the urban, rural and motorway windows are within the primary tolerance defined for the characteristic curve.
If the specified minimum requirement of 50 % is not met, the upper positive tolerance tol 1 may be increased by steps of 1 % until the 50 % of normal windows target is reached. When using this mechanism, tol 1 shall never exceed 30 %.

6. CALCULATION OF EMISSIONS

Then w j = k 11 h j + k 12
with k 11 = 1/(tol 1 – tol 2 )
and k 12 : tol 2 /(tol 2 – tol 1 )
If
MCO2,d,CCv–j×1−tol2∕100≤MCO2,d,j≤MCO2,d,CCv–j×1−tol1∕100
Then w j = k 21 h j + K 22
with k 21 = 1/(tol 2 – tol 1 )
and k 22 = k 21 = tol 2 /(tol 2 – tol 1 )
If

7.3. Urban, rural and motorway windows — Trip completeness
In this numerical example, the trip consists of 7 036 averaging windows. Table 5 lists the number of windows classified in urban, rural and motorway according to their average vehicle speed and divided in regions with respect to their distance to the CO 2 characteristic curve. The trip is complete since it comprises at least 15 % of urban, rural and motorway windows out of the total number of windows. In addition the trip is characterised as normal since at least 50 % of the urban, rural and motorway windows are within the primary tolerances defined for the characteristic curve.

3. EVALUATION OF THE MEASURED EMISSIONS USING A STANDARDISED WHEEL POWER FREQUENCY DISTRIBUTION
The power binning method uses the instantaneous emissions of the pollutants, m gas, i (g/s) calculated in accordance with Appendix 4.
The m gas, i values shall be classified in accordance with the corresponding power at the wheels and the classified average emissions per power class shall be weighted to obtain the emission values for a test with a normal power distribution according to the following points.

3.1. Sources for the actual wheel power
The actual wheel power P r,i shall be the total power to overcome air resistance, rolling resistance, road gradients, longitudinal inertia of the vehicle and rotational inertia of the wheels.
When measured and recorded, the wheel power signal shall use a torque signal meeting the linearity requirements laid down in Appendix 2, point 3.2.
As an alternative, the actual wheel power may be determined from the instantaneous CO 2 emissions following the procedure laid down in point 4 of this Appendix.

3.2 Classification of the moving averages to urban, rural and motorway
The standard power frequencies are defined for urban driving and for the total trip (see paragraph 3.4) and a separate evaluation of the emissions shall be made for the total trip and for the urban part. The three second moving averages calculated according to paragraph 3.3 shall therefore be allocated later to urban and extra-urban driving conditions according to the velocity signal (v i ) from the actual second i as outlined in Table 1-1.

Table 1-1
Speed ranges for the allocation of test data to urban, rural and motorway conditions in the power binning method

3.3. Calculation of the moving averages of the instantaneous test data
Three-second moving averages shall be calculated from all relevant instantaneous test data to reduce influences of possibly imperfect time alignment between emission mass flow and wheel power. The moving average values shall be computed in a 1 Hz frequency:

The P c,norm columns in Table 1-2 shall be de-normalised by multiplication with P drive , where P drive is the actual wheel power of the tested car in the type approval settings at the chassis dynamometer at v ref and a ref .
P c,j [kW] = P c,norm, j × P drive
Pdrive=vref3,6×f0+f1×vref+f2×v2ref+TMNEDC×aref×0,001
Where:

The driving resistance coefficients f 0 , f 1 , f 2 should be calculated with a least squares regression analysis from the following definition:
P Corrected /v = f 0 + f 1 × v + f 2 × v 2
with ( P Corrected /v ) being the road load force at vehicle velocity v for the NEDC test cycle defined in point 5.1.1.2.8 of Appendix 7 to Annex 4a of UNECE Regulation 83 — 07 series of amendments.
TM NEDC is the inertia class of the vehicle in the type approval test, [kg].

3.4.2. Correction of the wheel power classes
The maximum wheel power class to be considered is the highest class in Table 1-2 which includes (P rated × 0,9). The time shares of all excluded classes shall be added to the highest remaining class.
From each P c,norm,j the corresponding P c,j shall be calculated to define the upper and lower bounds in kW per wheel power class for the tested vehicle as shown in Figure 1.

Figure 1 Schematic picture for converting the normalised standardised power frequency into a vehicle specific power frequency
An example for this de-normalisation is given below.
Example for input data:
Parameter	Value
f 0 [N]	79,19
f 1 [N/(km/h)]	0,73
f 2 [N/(km/h) 2 ]	0,03
TM [kg]	1 470
P rated [kW]	120 (Example 1)
P rated [kW]	75 (Example 2)
Corresponding results:
P drive = 70 [km/h]/3,6 × (79,19 + 0,73 [N/(km/h)] × 70[km/h] + 0,03 [N/(km/h) 2 ] × (70 [km/h]) 2 + 1 470 [kg] × 0,45[m/s 2 ]) × 0,001

3.5. Classification of the moving average values
Each moving average value calculated according to point 3.2 shall be sorted into the de-normalised wheel power class into which the actual 3-second moving average wheel power P w , 3s,k fits. The de-normalised wheel power class limits have to be calculated according to point 3.3.
The classification shall be done for all three-second moving averages of the entire valid trip data as well as for the all urban trip parts. Additionally all moving averages classified to urban according to the velocity limits defined in Table 1-1 shall be classified into one set of urban power classes independently of the time when the moving average appeared in the trip.
Then the average of all three-second moving average values within a wheel power class shall be calculated for each wheel power class per parameter. The equations are described below and shall be applied once for the urban data set and once for the total data set.
Classification of the 3-second moving average values into power class j (j = 1 to 9):
if
P C,jlower bound<Pw,3s,k≤P C,jupper bound
then: class index for emissions and velocity = j.
The number of 3-second moving average values shall be counted for each power class:
if
P C,jlower bound<Pw,3s,k≤P C,jupper bound
then: counts j = n + 1 (counts j is counting the number of 3-second moving average emission value in a power class to check later the minimum coverage demands).

3.6. Check of power class coverage and of normality of power distribution
For a valid test the time shares of the single wheel power classes shall be in the ranges listed in Table 4.

Table 4
Minimum and maximum shares per power class for a valid test
	P c,norm,j [-]		Total trip		Urban trip parts	
Power class No	From >	to ≤	lower bound	upper bound	lower bound	upper bound

8	4,6	5,5	0 %	0,5 %	0 %	0,5 %
9	5,5		0 %	0,25 %	0 %	0,25 %
In addition to the requirements in Table 4, a minimum coverage of 5 counts is demanded for the total trip in each wheel power class up to the class containing 90 % of the rated power to provide a sufficient sample size.
A minimum coverage of five counts is required for the urban part of the trip in each wheel power class up to class No 5. If the counts in the urban part of the trip in a wheel power class above No 5 are less than five, the average class emission value shall be set to zero.

3.7. Averaging of the measured values per wheel power class
The moving averages sorted in each wheel power class shall be averaged as follows:
m–gas,j=∑all k in classjmgas,3s,kcountsj
v–j=∑all k in class jv3s,kcountsj
Where

j
wheel power class 1 to 9 according to Table 1

m–gas,j
average emission value of an exhaust gas component in a wheel power class (separate value for total trip data and for the urban parts of the trip), [g/s]

v–j
average velocity in a wheel power class (separate value for total trip data and for the urban parts of the trip), [km/h]

k
time step for moving average values.

3.8. Weighting of the average values per wheel power class
The average values of each wheel power class shall be multiplied with the time share, t C,j per class according to Table 1-2 and summed up to produce the weighted average value for each parameter. This value represents the weighted result for a trip with the standardised power frequencies. The weighted averages shall be computed for the urban part of the test data using the time shares for urban power distribution as well as for the total trip using the time shares for the total.
The equations are described below and shall be applied once for the urban data set and once for the total data set.
m–gas=∑9j=1m–gas,j×tc,j
v–=∑j=19v–j×tc,j

3.9. Calculation of the weighted distance-specific emission value
The time-based weighted averages of the emissions in the test shall be converted into distance-based emissions once for the urban data set and once for the total data set as follows:
For the total trip:
Mw,gas,d=1000×m–gas×3600v–
For the urban part of the trip:
Mw,gas,d,U=1000×m–gas,U×3600v–U
Using these formulas, weighted averages shall be calculated for the following pollutants for the total trip and for the urban part of the trip:

M w,NOx,d
weighted NO x test result in [mg/km]

M w,NOx,d,U
weighted NO x test result in [mg/km]

M w,CO,d
weighted CO test result in [mg/km]

M w,CO,d,U
weighted CO test result in [mg/km]

4. ASSESSMENT OF THE WHEEL POWER FROM THE INSTANTANEOUS CO 2 MASS FLOW
The power at the wheels (P w,i ) can be computed from the measured CO 2 mass flow in 1 Hz basis. For this calculation the vehicle-specific CO 2 lines (‘Veline’) shall be used.
The Veline shall be calculated from the vehicle type approval test in the WLTC according to the test procedure described in UNECE Global Technical Regulation No 15 — worldwide harmonised light vehicles test procedure (ECE/TRANS/180/Add.15).
The average wheel power per WLTC phase shall be calculated. in 1 Hz from the driven velocity and from the chassis dynamometer settings. All wheel power values below the drag power shall be set to the drag power value.
Pw,i=vi3,6×f0+f1×vi+f2×v2i+TM×ai×0,001

The resulting Veline equation defines the CO 2 mass flow as function of the wheel power:

Where

k WLTC
slope of the Veline from WLTC, [g/kWh]

D WLTC
intercept of the Veline from WLTC, [g/h].

The above equation can be used to provide P Wi for the classification of the measured emissions as described in point 3 with following additional conditions in the calculation

if CO2 i < 0,5 X D WLTC then P w,i = P drag	v in [m/s].

This may in particular require the PEMS testing of additional vehicles to validate the extended PEMS test family according to point 4.

3.4. Alternative PEMS test family
As an alternative to the provisions of points 3.1 to 3.2 the vehicle manufacturer may define a PEMS test family, which is identical to a single vehicle emission type. In this the requirement of point 4.1.2 for validating the PEMS test family shall not apply.

4. VALIDATION OF A PEMS TEST FAMILY

4.1. General requirements for validating a PEMS test family
4.1.1. The vehicle manufacturer presents a representative vehicle of the PEMS test family to the type-approval authority. The vehicle shall be subject to a PEMS test carried out by a Technical Service to demonstrate compliance of the representative vehicle with the requirements of this Annex.
4.1.2. The authority responsible for issuing the emission type-approval in accordance with Regulation (EC) No 715/2007 selects additional vehicles according to the requirements of point 4.2 of this Appendix for PEMS testing carried out by a Technical Service to demonstrate compliance of the selected vehicles with the requirements of this Annex. The technical criteria for selection of an additional vehicle according to point 4.2 of this Appendix shall be recorded with the test results.
4.1.3. With agreement of the type-approval authority, a PEMS test can also be driven by a different operator witnessed by a Technical Service, provided that at least the tests of the vehicles required by points 4.2.2 and 4.2.6 of this Appendix and in total at least 50 % of the PEMS tests required by this Appendix for validating the PEMS test family are driven by a Technical Service. In such case the Technical Service remains responsible for the proper execution of all PEMS tests pursuant to the requirements of this Annex.

4.1.4. A PEMS test results of a specific vehicle may be used for validating different PEMS test families according to the requirements of this Appendix under the following conditions:
the vehicles included in all PEMS test families to be validated are approved by a single authority according to the requirements of Regulation (EC) 715/2007 and this authority agrees to the use of the specific vehicle's PEMS test results for validating different PEMS test families,
each PEMS test family to be validated includes a vehicle emission type, which comprises the specific vehicle;
For each validation the applicable responsibilities are considered to be borne by the manufacturer of the vehicles in the respective family, regardless of whether this manufacturer was involved in the PEMS test of the specific vehicle emission type.

4.2. Selection of vehicles for PEMS testing when validating a PEMS test family

At least one vehicle configuration representative for the specified PMR H and one vehicle configuration representative for the specified PMR L of a PEMS test family shall be selected for testing. If the power-to-mass ratio of a vehicle deviates by not more than 5 % from the specified value for PMR H , or PMR L , the vehicle should be considered as representative for this value.
4.2.3. At least one vehicle for each transmission type (e.g. manual, automatic, DCT) installed in vehicles of the PEMS test family shall be selected for testing.

3. TRIP INDICATORS

3.1. Calculations

3.1.1. Data pre-processing
Dynamic parameters like acceleration, v · a pos or RPA shall be determined with a speed signal of an accuracy of 0,1 % above 3 km/h and a sampling frequency of 1 Hz. This accuracy requirement is generally fulfilled by wheel (rotational) speed signals.
The speed trace shall be checked for faulty or implausible sections. The vehicle speed trace of such sections is characterised by steps, jumps, terraced speed traces or missing values. Short faulty sections shall be corrected, for example by data interpolation or benchmarking against a secondary speed signal. Alternatively, short trips containing faulty sections could be excluded from the subsequent data analysis. In a second step the acceleration values shall be ranked in ascending order, in order to determine the acceleration resolution a res = (minimum acceleration value > 0).
If a res ≤ 0,01 m/s 2 , the vehicle speed measurement is accurate enough.
If 0,01 < a res ≤ r max m/s 2 , smoothing by using a T4253 Hanning filter.
If a res > r max m/s 2 , the trip is invalid.
The T4253 Hanning filter performs the following calculations: The smoother starts with a running median of 4, which is centred by a running median of 2. It then re-smoothes these values by applying a running median of 5, a running median of 3, and Hanning (running weighted averages). Residuals are computed by subtracting the smoothed series from the original series. This whole process is then repeated on the computed residuals. Finally, the smoothed residuals are computed by subtracting the smoothed values obtained the first time through the process.
The correct speed trace builds the basis for further calculations and binning as described in paragraph 3.1.2.

3.1.2. Calculation of distance, acceleration and v · a
The following calculations shall be performed over the whole time-based speed trace (1 Hz resolution) from second 1 to second t t (last second).
The distance increment per data sample shall be calculated as follows:
d i = v i /3,6, i = 1 to N t
Where:
d i is the distance covered in time step i [m]
v i is the actual vehicle speed in time step i [km/h]
N t is the total number of samples
The acceleration shall be calculated as follows:
a i = ( v i + 1 – v i – 1 )/(2 · 3,6), i = 1 to N t
Where:
a i is the acceleration in time step i [m/s 2 ]. For i = 1: v i – 1 = 0, for i = N t : v i + 1 = 0.
The product of vehicle speed per acceleration shall be calculated as follows:
(v · a) i = v i · a i /3,6, i = 1 to N t
Where:
(v · a) i is the product of the actual vehicle speed per acceleration in time step i [m 2 /s 3 or W/kg].

3.1.3. Binning of the results
After the calculation of a i and (v · a) i , the values v i , d i , a i and (v · a) i shall be ranked in ascending order of the vehicle speed.
All datasets with v i ≤ 60 km/h belong to the ‘ urban ’ speed bin, all datasets with 60 km/h < v i ≤ 90 km/h belong to the ‘ rural ’ speed bin and all datasets with v i > 90 km/h belong to the ‘ motorway ’ speed bin.
The number of datasets with acceleration values a i > 0,1 m/s 2 shall be bigger or equal to 150 in each speed bin.
For each speed bin the average vehicle speed
v–k
shall be calculated as follows:
v–k=∑ivi,k∕Nk
, i = 1 to N k ,k = u,r,m
Where:
N k is the total number of samples of the urban, rural, and motorway shares.

3.1.4. Calculation of v · a pos _[95] per speed bin
The 95th percentile of the v · a pos values shall be calculated as follows:
The (v · a) i,k values in each speed bin shall be ranked in ascending order for all datasets with a i,k ≥ 0,1 m/s 2 and the total number of these samples M k shall be determined.
Percentile values are then assigned to the (v · a pos ) j,k values with a i,k ≥ 0,1 m/s 2 as follows:
The lowest v · a pos value gets the percentile 1/ M k , the second lowest 2/ M k , the third lowest 3/ M k and the highest value M k /M k =100 %.
(v · a pos ) k _[95] is the (v · a pos ) j,k value, with j/M k = 95 %. If j/M k = 95 % cannot be met, (v · a pos ) k _[95] shall be calculated by linear interpolation between consecutive samples j and j + 1 with j/M k < 95 % and ( j + 1)/ M k > 95 %.
The relative positive acceleration per speed bin shall be calculated as follows:
RPA k = Σ j (Δ t · ( v · a pos ) j,k )/Σ i d i,k , j = 1 to M k ,i = 1 to N k ,k = u,r,m
Where:
RPA k is the relative positive acceleration for urban, rural and motorway shares in [m/s 2 or kWs/(kg*km)]

time difference equal to 1 second

M k
the sample number for urban, rural and motorway shares with positive acceleration

4.1. General
The cumulative positive elevation gain of an RDE trip shall be calculated as a three-step procedure, consisting of: (i) the screening and principle verification of data quality; (ii) the correction of instantaneous vehicle altitude data; and (iii) the calculation of the cumulative positive elevation gain.

4.2. Screening and principle verification of data quality

for 200 m < d < ( d e – 200 m )

for d ≥ ( d e – 200 m )
h int,sm ,1 ( d ) = h int,sm ,1 ( d – 1 m ) + road grade ,1 ( d ), d = d a + 1 to d e

Figure 1 Illustration of the procedure to smooth the interpolated altitude signals

4.4.3. Calculation of the final result
The positive cumulative elevation gain of a trip shall be calculated by integrating all positive interpolated and smoothed road grades, i.e. road grade,2 (d) . The result should be normalised by the total test distance d tot and expressed in meters of cumulative elevation gain per 100 kilometres of distance.

5. NUMERICAL EXAMPLE
Tables 1 and 2 show the steps performed in order to calculate the positive elevation gain on the basis of data recorded during an on-road test performed with PEMS. For the sake of brevity an extract of 800 m and 160 s is presented here.

5.1. Screening and principle verification of data quality
The screening and principle verification of data quality consists of two steps. First, the completeness of vehicle speed data is checked. No data gaps related to vehicle speed are detected in the present data sample (see Table 1). Second, the altitude data are checked for completeness; in the data sample, altitude data related to seconds 2 and 3 are missing. The gaps are filled by interpolating the GPS signal. In addition, the GPS altitude is verified by a topographic map; this verification includes the altitude h(0) at the start of the trip. Altitude data related to seconds 112-114 are corrected on the basis of the topographic map to satisfy the following condition:
h GPS (t) – h map (t) < – 40 m
As result of the applied data verification, the data in the fifth column h(t) are obtained.

5.2. Correction of instantaneous vehicle altitude data
As a next step, the altitude data h(t) of seconds 1 to 4, 111 to 112 and 159 to 160 are corrected assuming the altitude values of seconds 0, 110 and 158 respectively since the following condition applies:
| h(t) – h ( t – 1)| > ( v(t) /3,6 * sin 45°)
As result of the applied data correction, the data in the sixth column h corr (t) are obtained. The effect of the applied verification and correction steps on the altitude data is depicted in Figure 2.

5.3. Calculation of the cumulative positive elevation gain

5.3.1. Establishment of a uniform spatial resolution
The instantaneous distance d i is calculated by dividing the instantaneous vehicle speed measured in km/h by 3,6 (Column 7 in Table 1). Recalculating the altitude data to obtain a uniform spatial resolution of 1 m yields the discrete way points d (Column 1 in Table 2) and their corresponding altitude values h int (d) (Column 7 in Table 2). The altitude of each discrete way point d is calculated through interpolation of the measured instantaneous altitude h corr as:
hint0=120,3+120,3−120,30,1−0,0×0−0=120,3000
hint520=132,5+132,6−132,5523,6−519,9×520−519,9=132,5027

5.3.2. Additional data smoothing
In Table 2, the first and last discrete way points are: d a = 0 m and d e = 799 m, respectively. The altitude data of each discrete way point is smoothed by applying a two-step procedure. The first smoothing run consists of:
roadgrade,10=hint200 m−hint00+200 m=120,9682−120,3000200=0,0033
chosen to demonstrate the smoothing for d ≤ 200 m
roadgrade,1320=hint520−hint120520−120=132,5027−121,9808400=0,0288
chosen to demonstrate the smoothing for 200 m < d < (599 m )
roadgrade,1720=hint799−hint520799−520=121,2000−132,5027279=−0,0405
chosen to demonstrate the smoothing for d ≥ (599 m )
The smoothed and interpolated altitude is calculated as:
h int,sm ,1 (0) = h int (0) + road grade ,1 (0) = 120,3 + 0,0033 ≈ 120,3033 m
h int,sm ,1 (799) = h int,sm ,1 (798) + road grade ,1 (799) = 121,2550 – 0,0220 = 121,2330 m
Second smoothing run:
roadgrade,20=hint,sm,1200−hint,sm,10200=119,9618−120,3033200=−0,0017
chosen to demonstrate the smoothing for d ≤ 200 m
roadgrade,2320=hint,sm,1520−hint,sm,1120520−120=123,6809−120,1843400=0,0087
chosen to demonstrate the smoothing for 200 m < d < (599 m )
roadgrade,2720=hint,sm,1799−hint,sm,1520799−520=121,2330−123,6809279=−0,0088
chosen to demonstrate the smoothing for d ≥ (599 m )

5.3.3. Calculation of the final result
The positive cumulative elevation gain of a trip is calculated by integrating all positive interpolated and smoothed road grades, i.e. road grade,2 (d) . For the presented example the total covered distance was d tot = 139,7 km and all positive interpolated and smoothed road grades were of 516 m. Therefore a positive cumulative elevation gain of 516 × 100/139,7 = 370 m/100 km was achieved.

3. DATA EXCHANGE AND REPORTING FORMAT

3.1. General
Emission values as well as any other relevant parameters shall be reported and exchanged as csv-formatted data file. Parameter values shall be separated by a comma, ASCII-Code #h2C. The decimal marker of numerical values shall be a point, ASCII-Code #h2E. Lines shall be terminated by carriage return, ASCII-Code #h0D. No thousands separators shall be used.

3.2. Data exchange
Data shall be exchanged between the measurement systems and the data evaluation software by means of a standardised reporting file that contains a minimum set of mandatory and optional parameters. The data exchange file shall be structured as follows: The first 195 lines shall be reserved for a header that provides specific information about, e.g. the test conditions, the identity and calibration of the PEMS equipment (Table 1). Lines 198-200 shall contain the labels and units of parameters. Lines 201 and all consecutive data lines shall comprise the body of the data exchange file and report parameter values (Table 2). The body of the data exchange file shall contain at least as many data lines as the test duration in seconds multiplied by the recording frequency in Hertz.

3.3. Intermediate and final results
Manufacturers shall record summary parameters of intermediate results as structured in Table 3. The information in Table 3 shall be obtained prior to the application of the data evaluation methods laid down in Appendices 5 and 6.
The vehicle manufacturer shall record the results of the two data evaluation methods in separate files. The results of the data evaluation with the method described in Appendix 5 shall be reported according to Tables 4, 5 and 6. The results of the data evaluation with the method described in Appendix 6 shall be reported according to Tables 7, 8 and 9. The header of the data reporting file shall be composed of three parts. The first 95 lines shall be reserved for specific information about the settings of the data evaluation method. Lines 101-195 shall report the results of the data evaluation method. Lines 201-490 shall be reserved for reporting the final emission results. Line 501 and all consecutive data lines comprise the body of the data reporting file and shall contain the detailed results of the data evaluation.

2. Technical requirements

2.1. Introduction
The procedure includes the evaporative emissions test and two additional tests, one for the aging of the carbon canister, as described in point 5.1, and one for the permeability of the fuel storage system, as described in point 5.2.
The evaporative emissions test (Figure 1) is designed to determine hydrocarbon evaporative emissions as a consequence of diurnal temperatures fluctuation, hot soaks during parking, and urban driving.
2.2 The evaporative emissions test consists of:
(a) Test drive including an urban (Part One) and an extra-urban (Part Two) driving cycle, followed by two urban (Part One) driving cycles,
(b) Hot soak loss determination,
(c) Diurnal loss determination.
The mass emissions of hydrocarbons from the hot soak and the diurnal loss phases are added up together with the permeability factor to provide an overall result for the test.

3. Vehicle and fuel

3.1. Vehicle
3.1.1. The vehicle shall be in good mechanical condition and have been run in and driven at least 3 000  km before the test. For the purpose of the determination of evaporative emissions, the mileage and the age of the vehicle used for certification shall be recorded. The evaporative emission control system shall be connected and have been functioning correctly over the run in period and the carbon canister(s) shall have been subject to normal use, neither undergoing abnormal purging nor abnormal loading. The carbon canister(s) aged according to the Procedure set out in point 5.1 shall be connected as described in Figure 1.

3.2. Fuel
3.2.1. The Type I E10 reference fuel specified in Annex IX to Regulation (EC) No 692/2008 shall be used. For the purposes of this Regulation, E10 reference shall mean the Type I reference fuel, except for the canister aging, as set out in point 5.1.

4. Test equipment for evaporative test

4.1. Chassis dynamometer
The chassis dynamometer shall meet the requirements of Appendix 1 of Annex 4a to UN/ECE Regulation No 83.

4.2. Evaporative emission measurement enclosure
The evaporative emission measurement enclosure shall meet the requirements of paragraph 4.2 of Annex 7 to UN/ECE Regulation No 83.

4.8. Additional Equipment
The additional equipment shall meet the requirements of paragraph 4.9 of Annex 7 to UN/ECE Regulation No 83.

5. Test procedure

5.1. Canister(s) bench aging
Before performing the hot soak and diurnal losses sequences, the canister(s) must be aged according the following procedure described in Figure 2.

Figure 2 Canister bench aging procedure

5.1.1. Temperature conditioning test
In a dedicated temperature chamber, the canister(s) is (are) cycled between temperatures from – 15 °C to 60 °C, with 30 min of stabilisation at – 15 °C and 60 °C. Each cycle shall last 210 min as in Figure 3. The temperature gradient shall be as close as possible to 1 °C/min. No forced air flow should pass through the canister(s).
The cycle is repeated 50 times consecutively. In total, this operation will last 175 hours.

Figure 3 Temperature conditioning cycle

5.1.2. Canister vibration conditioning test
After the temperature aging procedure, the canister(s) is (are) shaken along the vertical axis with the canister(s) mounted as per its orientation in the vehicle with overall Grms > 1,5 m/sec 2 with frequency of 30 ± 10 Hz. The test shall last 12 hours.

Grms
The root mean square (rms) value of the vibration signal is calculated by squaring the magnitude of the signal at every point, finding the average (mean) value of the squared magnitude, then taking the square root of the average value. The resulting number is the Grms metric.

5.1.3. Canister Fuel aging test

5.1.3.1. Fuel Aging for 300 cycles
5.1.3.1.1. After the temperature conditioning test and vibration test, the canister(s) is aged with a mixture of Type I E10 market fuel as specified in point 5.1.3.1.1.1 below and nitrogen or air with a 50 ± 15 percent fuel vapour volume. The fuel vapour fill rate must be kept between 60 ± 20 g/h.
The canister(s) is (are) loaded to the corresponding breakthrough. Breakthrough shall be considered as the point at which the cumulative quantity of hydrocarbons emitted is equal to 2 grams. As an alternative, the loading is deemed completed when the equivalent concentration level at the vent hole reaches 3 000 ppm.
5.1.3.1.1.1 The E10 market fuel used for this test shall fulfil the same requirements as an E10 reference fuel for the following points:
Density at 15 °C
Vapour Pressure (DVPE)
Distillation (evaporates only)
Hydrocarbon analysis (olefins, aromatics, benzene only)
Oxygen content
Ethanol content
5.1.3.1.2. The canister(s) shall be purged according the procedure of paragraph 5.1.3.8 of Annex 7 to UN/ECE Regulation No 83. The standard conditions are 273,2 K and 101,33 kPa.
The canister must be purged between 5 minutes to 1 hour maximum after loading.
5.1.3.1.3. The steps of the procedure set out in points 5.1.3.1.1 and.5.1.3.1.2 shall be repeated 50 times, followed by a measurement of the Butane Working Capacity (BWC), meant as the ability of an activated carbon canister to absorb and desorb butane from dry air under specified conditions, in 5 butane cycles, as described in point 5.1.3.1.4 below. The fuel vapour ageing will continue until 300 cycles are reached. A measurement of the BWC in 5 butane cycles, as set out in point 5.1.3.1.4, will be made after the 300 cycles.
5.1.3.1.4. After 50 and 300 Fuel aging cycles, a measurement of BWC is performed. This measurement consists of loading the canister according to paragraph 5.1.6.3, of Annex 7 to UN/ECE Regulation No 83 until breakthrough. The BWC is recorded.

Alternatively, the temperature may be measured at another location providing that it is adjusted to represent the temperature measured at the hottest location using good engineering judgement.
Catalyst temperature shall be measured at a minimum rate of one hertz (one measurement per second).
The measured catalyst temperature results shall be tabulated into a histogram with temperature groups of no larger than 25 °C.
2.3.1.4. Bench-ageing time. Bench ageing time shall be calculated using the bench ageing time (BAT) equation as follows:

th
The time (in hours) measured within the prescribed temperature bin of the vehicle's catalyst temperature histogram adjusted to a full useful life basis e.g., if the histogram represented 400 km, and useful life is 160 000 km; all histogram time entries would be multiplied by 400 (160 000/400).

Total te

(a) Measure time-at-temperature data in the catalyst system on the catalyst ageing bench following the SBC. Catalyst temperature shall be measured at the highest temperature location of the hottest catalyst in the system. Alternatively, the temperature may be measured at another location providing that it is adjusted to represent the temperature measured at the hottest location.
Catalyst temperature shall be measured at a minimum rate of one hertz (one measurement per second) during at least 20 minutes of bench ageing. The measured catalyst temperature results shall be tabulated into a histogram with temperature groups of no larger than 10 °C.
(b) The BAT equation shall be used to calculate the effective reference temperature by iterative changes to the reference temperature (Tr) until the calculated ageing time equals or exceeds the actual time represented in the catalyst temperature histogram. The resulting temperature is the effective reference temperature on the SBC for that catalyst system and ageing bench.
2.3.1.6. Catalyst Ageing Bench. The catalyst ageing bench shall follow the SBC and deliver the appropriate exhaust flow, exhaust constituents, and exhaust temperature at the face of the catalyst.
All bench ageing equipment and procedures shall record appropriate information (such as measured A/F ratios and time-at-temperature in the catalyst) to assure that sufficient ageing has actually occurred.

2.3.2. Vehicles with Compression Ignition Engines
2.3.2.1. The following bench ageing procedure is applicable for compression-ignition vehicles including hybrid vehicles.

Appendix 1 Standard Bench Cycle (SBC)

1. Introduction
The standard ageing durability procedure consists of ageing a catalyst/oxygen sensor system on an ageing bench which follows the standard bench cycle (SBC) described in this Appendix. The SBC requires use of an ageing bench with an engine as the source of feed gas for the catalyst. The SBC is a 60-second cycle which is repeated as necessary on the ageing bench to conduct ageing for the required period of time. The SBC is defined based on the catalyst temperature, engine air/fuel (A/F) ratio, and the amount of secondary air injection which is added in front of the first catalyst.

2. Catalyst Temperature Control
2.1. Catalyst temperature shall be measured in the catalyst bed at the location where the highest temperature occurs in the hottest catalyst. Alternatively, the feed gas temperature may be measured and converted to catalyst bed temperature using a linear transform calculated from correlation data collected on the catalyst design and ageing bench to be used in the ageing process.
2.2. Control the catalyst temperature at stoichiometric operation (01 to 40 seconds on the cycle) to a minimum of 800 °C (± 10 °C) by selecting the appropriate engine speed, load, and spark timing for the engine. Control the maximum catalyst temperature that occurs during the cycle to 890 °C (± 10 °C) by selecting the appropriate A/F ratio of the engine during the ‘rich’ phase described in the table below.
2.3. If a low control temperature other than 800 °C is utilized, the high control temperature shall be 90 °C higher than the low control temperature.

Standard Bench Cycle (SBC)
Time(seconds)	Engine Air/Fuel Ratio	Secondary Air Injection
1-40	Stoichiometric with load, spark timing and engine speed controlled to achieve a minimum catalyst temperature of 800 °C	None
41-45	‘Rich’ (A/F ratio selected to achieve a maximum catalyst temperature over the entire cycle of 890 °C or 90 °C higher than lower control temperature)	None
46-55	‘Rich’ (A/F ratio selected to achieve a maximum catalyst temperature over the entire cycle of 890 °C or 90 °C higher than lower control temperature)	3 % (± 1 %)
56-60	Stoichiometric with load, spark timing and engine speed controlled to achieve a minimum catalyst temperature of 800 °C	3 % (± 1 %)

3. Ageing Bench Equipment and Procedures
3.1. Ageing Bench Configuration. The ageing bench shall provide the appropriate exhaust flow rate, temperature, air-fuel ratio, exhaust constituents and secondary air injection at the inlet face of the catalyst.
The standard ageing bench consists of an engine, engine controller, and engine dynamometer. Other configurations may be acceptable (e.g. whole vehicle on a dynamometer, or a burner that provides the correct exhaust conditions), as long as the catalyst inlet conditions and control features specified in this Appendix are met.
A single ageing bench may have the exhaust flow split into several streams providing that each exhaust stream meets the requirements of this appendix. If the bench has more than one exhaust stream, multiple catalyst systems may be aged simultaneously.
3.2. Exhaust System Installation. The entire catalyst(s)-plus-oxygen sensor(s) system, together with all exhaust piping which connects these components, will be installed on the bench. For engines with multiple exhaust streams (such as some V6 and V8 engines), each bank of the exhaust system will be installed separately on the bench in parallel.
For exhaust systems that contain multiple in-line catalysts, the entire catalyst system including all catalysts, all oxygen sensors and the associated exhaust piping will be installed as a unit for ageing. Alternatively, each individual catalyst may be separately aged for the appropriate period of time.
3.3. Temperature Measurement. Catalyst temperature shall be measured using a thermocouple placed in the catalyst bed at the location where the highest temperature occurs in the hottest catalyst. Alternatively, the feed gas temperature just before the catalyst inlet face may be measured and converted to catalyst bed temperature using a linear transform calculated from correlation data collected on the catalyst design and ageing bench to be used in the ageing process. The catalyst temperature shall be stored digitally at the speed of 1 hertz (one measurement per second).
3.4. Air/Fuel Measurement. Provisions shall be made for the measurement of the air/fuel (A/F) ratio (such as a wide-range oxygen sensor) as close as possible to the catalyst inlet and outlet flanges. The information from these sensors shall be stored digitally at the speed of 1 hertz (one measurement per second).
3.5. Exhaust Flow Balance. Provisions shall be made to assure that the proper amount of exhaust (measured in grams/second at stoichiometry, with a tolerance of ± 5 grams/second) flows through each catalyst system that is being aged on the bench.
The proper flow rate is determined based upon the exhaust flow that would occur in the original vehicle’s engine at the steady state engine speed and load selected for the bench ageing in Paragraph 3.6. of this Appendix.
3.6. Setup. The engine speed, load, and spark timing are selected to achieve a catalyst bed temperature of 800 °C (± 10 °C) at steady-state stoichiometric operation.
The air injection system is set to provide the necessary air flow to produce 3,0 % oxygen (± 0,1 %) in the steady-state stoichiometric exhaust stream just in front of the first catalyst. A typical reading at the upstream A/F measurement point (required in paragraph 5) is lambda 1,16 (which is approximately 3 % oxygen).
With the air injection on, set the ‘Rich’ A/F ratio to produce a catalyst bed temperature of 890 °C (± 10 °C). A typical A/F value for this step is lambda 0,94 (approximately 2 % CO).
3.7. Ageing Cycle. The standard bench ageing procedures use the standard bench cycle (SBC). The SBC is repeated until the amount of ageing calculated from the bench ageing time equation (BAT) is achieved.
3.8. Quality Assurance. The temperatures and A/F ratio in paragraphs 3.3. and 3.4. of this appendix shall be reviewed periodically (at least every 50 hours) during ageing. Necessary adjustments shall be made to assure that the SBC is being appropriately followed throughout the ageing process.
After the ageing has been completed, the catalyst time-at-temperature collected during the ageing process shall be tabulated into a histogram with temperature groups of no larger than 10 °C. The BAT equation and the calculated effective reference temperature for the ageing cycle according to Paragraph 2.3.1.4 of Annex VII will be used to determine if the appropriate amount of thermal ageing of the catalyst has in fact occurred. Bench ageing will be extended if the thermal effect of the calculated ageing time is not at least 95 % of the target thermal ageing.
3.9. Startup and Shutdown. Care should be taken to assure that the maximum catalyst temperature for rapid deterioration (e.g., 1 050 °C) does not occur during startup or shutdown. Special low temperature startup and shutdown procedures may be used to alleviate this concern.

4. Experimentally Determining the R-Factor for Bench Ageing Durability Procedures
4.1. The R-Factor is the catalyst thermal reactivity coefficient used in the bench ageing time (BAT) equation. Manufacturers may determine the value of R experimentally using the following procedures.
4.1.1. Using the applicable bench cycle and ageing bench hardware, age several catalysts (minimum of 3 of the same catalyst design) at different control temperatures between the normal operating temperature and the damage limit temperature. Measure emissions (or catalyst inefficiency (1-catalyst efficiency)) for each exhaust constituent. Assure that the final testing yields data between one- and two-times the emission standard.
4.1.2. Estimate the value of R and calculate the effective reference temperature (Tr) for the bench ageing cycle for each control temperature according to Paragraph 2.4.4 of Annex VII.
4.1.3. Plot emissions (or catalyst inefficiency) versus ageing time for each catalyst. Calculate the least-squared best-fit line through the data. For the data set to be useful for this purpose the data should have an approximately common intercept between 0 and 6 400 km. See the following graph for an example.
4.1.4. Calculate the slope of the best-fit line for each ageing temperature.
4.1.5. Plot the natural log (ln) of the slope of each best-fit line (determined in step 4.1.4.) along the vertical axis, versus the inverse of ageing temperature (1/(ageing temperature, deg K)) along the horizontal axis, Calculate the least squared best-fit lines through the data. The slope of the line is the R-factor. See the following graph for an example.
4.1.6. Compare the R-factor to the initial value that was used in Step 4.1.2. If the calculated R-factor differs from the initial value by more than 5 %, choose a new R-factor that is between the initial and calculated values, and then repeat Steps 2-6 to derive a new R-factor. Repeat this process until the calculated R-factor is within 5 % of the initially assumed R-factor.
4.1.7. Compare the R-factor determined separately for each exhaust constituent. Use the lowest R-factor (worst case) for the BAT equation.

Appendix 2 Standard Diesel Bench Cycle (SDBC)

1. Introduction
For particulate filters, the number of regenerations is critical to the ageing process. For systems that require desulphurisation cycles (e.g. NOx storage catalysts), this process is also significant.
The standard diesel bench ageing durability procedure consists of ageing an aftertreatment system on an ageing bench which follows the standard bench cycle (SDBC) described in this Appendix. The SDBC requires use of an ageing bench with an engine as the source of feed gas for the system.
During the SDBC, the regeneration/desulphurisation strategies of the system shall remain in normal operating condition.
2. The Standard Diesel Bench Cycle reproduces the engine speed and load conditions that are encountered in the SRC cycle as appropriate to the period for which durability is to be determined. In order to accelerate the process of ageing, the engine settings on the test bench may be modified to reduce the system loading times. For example the fuel injection timing or EGR strategy may be modified.

3. Ageing Bench Equipment and Procedures
3.1. The standard ageing bench consists of an engine, engine controller, and engine dynamometer. Other configurations may be acceptable (e.g. whole vehicle on a dynamometer, or a burner that provides the correct exhaust conditions), as long as the aftertreatment system inlet conditions and control features specified in this Appendix are met.
A single ageing bench may have the exhaust flow split into several streams providing that each exhaust stream meets the requirements of this appendix. If the bench has more than one exhaust stream, multiple aftertreatment systems may be aged simultaneously.
3.2. Exhaust System Installation. The entire aftertreatment system, together with all exhaust piping which connects these components, will be installed on the bench. For engines with multiple exhaust streams (such as some V6 and V8 engines), each bank of the exhaust system will be installed separately on the bench.
The entire aftertreatment system will be installed as a unit for ageing. Alternatively, each individual component may be separately aged for the appropriate period of time.

Explanatory note:
The OBD thresholds set out in the table are subject to a review to be conducted by the Commission by 1 September 2014 . Where the thresholds appear to be not technically feasible, their values or the mandatory date of application are to be amended accordingly, considering the effects of other new requirements and tests that will be introduced for Euro 6 vehicles. Where the review shows an environmental need as well as technical feasibility and a net monetised benefit, more stringent values need to be adopted and OBD threshold limits for particle numbers or, where applicable, other regulated pollutants introduced. In doing so, appropriate lead time for introducing the technical developments has to be given to the industry.
Inserted by Commission Regulation (EU) No 459/2012 of 29 May 2012 amending Regulation (EC) No 715/2007 of the European Parliament and of the Council and Commission Regulation (EC) No 692/2008 as regards emissions from light passenger and commercial vehicles (Euro 6) (Text with EEA relevance).
2.3.4. Until three years after the dates specified in Article 10(4) and (5) of Regulation (EC) No 715/2007 for new type approvals and new vehicles respectively, the following OBD threshold limits shall be applied to vehicles that are type approved according to the Euro 6 emission limits set out in Table 2 of Annex I to Regulation (EC) No 715/2007, upon the choice of the manufacturer:

Preliminary Euro 6 OBD threshold limits
		Reference mass (RM) (kg)	Mass of carbon monoxide		Mass of non‐methane hydrocarbons		Mass of oxides of nitrogen		Mass of particulate matter Positive ignition particulate mass limits apply only to vehicles with direct injection engines.	
			(CO) (mg/km)		(NMHC) (mg/km)		(NOx) (mg/km)		(PM) (mg/km)

2.4. In addition to the provisions of section 3.2.1 of Annex 11 to UN/ECE Regulation 83 the manufacturer may temporarily disable the OBD system in the following conditions:
(a) For flex fuel or mono/bi fuel gas vehicles during 1 minute after re-fuelling to allow for the recognition of fuel quality and composition by the ECU;
(b) For bi fuel vehicles during 5 seconds after fuel switching to allow for readjusting engine parameters.
The manufacturer may deviate from these time limits if it can demonstrate that stabilisation of the fuelling system after re-fuelling or fuel switching takes longer for justified technical reasons. In any case, the OBD system shall be re-enabled as soon as either the fuel quality and composition is recognised or the engine parameters are readjusted.
2.5. Section 3.3.3.1 of Annex 11 to UNECE Regulation No 83 shall be understood as:
The OBD system shall monitor the reduction in the efficiency of the catalytic converter with respect to emissions of NMHC and NOx. Manufacturers may monitor the front catalyst alone or in combination with the next catalyst(s) downstream. Each monitored catalyst or catalyst combination shall be considered malfunctioning when the emissions exceed the NMHC or NOx threshold limits provided for in Section 2.3 of this Annex. By way of derogation, the requirement of monitoring the reduction in the efficiency of the catalytic converter with respect to NOx emissions shall only apply as from the dates set out in Article 17.
2.6. Section 3.3.3.3 of Annex 11 to UN/ECE Regulation 83 shall mean that the deterioration of all oxygen sensors fitted and used for monitoring malfunctions of the catalytic converter according to the requirements of this Annex shall be monitored.
2.7. In addition to the requirements of section 3.3.3 of Annex 11 to UN/ECE Regulation 83, for direct injection positive ignition engines any malfunction, which may lead to emissions exceeding the particulate threshold limits provided for by section 2.3 of this Annex and which has to be monitored according to the requirements of this Annex for compression ignition engines, shall be monitored.
2.8. In addition to the requirements of section 3.3.4 of Annex 11 to UN/ECE Regulation 83, malfunctions and the reduction in efficiency of the EGR system shall be monitored.
2.9. In addition to the requirements of section 3.3.4 of Annex 11 to UN/ECE Regulation 83, malfunctions and the reduction in efficiency of a NOx aftertreatment system using a reagent and the reagent dosing sub-system shall be monitored.
2.10. In addition to the requirements of section 3.3.4 of Annex 11 to UN/ECE Regulation 83, malfunctions and the reduction in efficiency of NOx aftertreatment not using a reagent shall be monitored.
2.11. In addition to the requirements of section 6.3.2 of Appendix 1 to Annex 11 to UN/ECE Regulation 83, the manufacturer shall demonstrate that malfunctions of the EGR flow and cooler are detected by the OBD system during its approval test.
2.12. References to ‘HC’ (hydrocarbons) shall be read as ‘NMHC’ (non-methane hydrocarbons) in section 6.4.1.2 of Appendix 1 to Annex 11 to UN/ECE Regulation 83.
2.13. In addition to the requirements of section 6.5.1.3 of Appendix 1 to Annex 11 of UN/ECE Regulation 83, all data required to be stored in relation to OBD in-use performance according to the provisions of section 3.6 of Appendix 1 of this Annex shall be available through the serial data port on the standardised data link connector according to the specifications given in section 6.5.3 of Appendix 1 to Annex 11 of UN/ECE Regulation 83.
2.14. Contrary to point 3.3.5 of Annex 11 to UN/ECE Regulation No 83, the following devices shall be monitored for total failure or removal if the latter resulted in exceeding the applicable emission limits:
as from 1 September 2011 , a particulate trap fitted to compression ignition engines as a separate unit or integrated into a combined emission control device,
for vehicles certified against either the OBD threshold limits shown in the tables set out in point 2.3.3 or 2.3.4, a NO x aftertreatment system fitted to compression ignition engines as a separate unit or integrated into a combined emission control device,
for vehicles certified against either the OBD threshold limits shown in the tables set out in point 2.3.3 or 2.3.4, a diesel oxidation catalyst (DOC) fitted to compression ignition engines as a separate unit or integrated into a combined emission control device.
The devices referred to in the first paragraph shall also be monitored for any failure that would result in exceeding the applicable OBD threshold limits.

3. ADMINISTRATIVE PROVISIONS FOR DEFICIENCIES OF OBD SYSTEMS
3.1. In considering the request for granting type-approval to a vehicle with a deficiency or deficiencies as set out in Article 6(2), the approval authority shall determine whether compliance with the requirements of this Annex is infeasible or unreasonable.
3.2. The approval authority shall take into consideration data from the manufacturer that details such factors as, but not limited to, technical feasibility, lead time and production cycles including phase-in or phase-out of engines or vehicle designs and programmed upgrades of computers, the extent to which the resultant OBD system will be effective in complying with the requirements of this Regulation and that the manufacturer has demonstrated an acceptable level of effort toward compliance with the requirements of this Regulation.
3.3. The approval authority shall not accept any deficiency request that includes the complete lack of a required diagnostic monitor or of mandated recording and reporting of data related to a monitor.
3.4. The approval authority will not accept any deficiency request that does not respect the OBD threshold limits in Section 2.3.
3.5. In determining the identified order of deficiencies, deficiencies relating to sections 3.3.3.1, 3.3.3.2 and 3.3.3.3 of Annex 11 of UN/ECE Regulation 83 for positive-ignition engines and sections 3.3.4.1, 3.3.4.2 and 3.3.4.3 of Annex 11 of UN/ECE Regulation 83 for compression-ignition engines shall be identified first.
3.6. Prior to or at the time of type-approval, no deficiency shall be granted in respect of the requirements of section 6.5, except section 6.5.3.4 of Appendix 1 to Annex 11 of UN/ECE Regulation 83.

3.6. Deficiency period
3.6.1. A deficiency may be carried-over for a period of two years after the date of type-approval of the vehicle type unless it can be adequately demonstrated that substantial vehicle hardware modifications and additional lead-time beyond two years would be necessary to correct the deficiency. In such a case, the deficiency may be carried-over for a period not exceeding three years.
3.6.2. A manufacturer may request that the approval authority grant a deficiency retrospectively when such a deficiency is discovered after the original type-approval. In this case, the deficiency may be carried-over for a period of two years after the date of notification to the approval authority unless it can be adequately demonstrated that substantial vehicle hardware modifications and additional lead-time beyond two years would be necessary to correct the deficiency. In such a case, the deficiency may be carried-over for a period not exceeding three years.
3.7. The approval authority shall notify its decision in granting a deficiency request in accordance with Article 6(2).

4. ACCESS TO OBD INFORMATION
4.1. Requirements for access to OBD information are specified in section 5 of Annex 11 to UN/ECE Regulation 83. The exceptions to these requirements are described in the following sections.

Appendix 1 FUNCTIONAL ASPECTS OF ON-BOARD DIAGNOSTIC (OBD) SYSTEMS

1. INTRODUCTION
1.1. This Appendix describes the procedure of the test according to section 2 of this Annex.

2. TECHNICAL REQUIREMENTS
2.1. The technical requirements and specifications shall be those set out in Appendix 1 to Annex 11 to UN/ECE Regulation No 83 with the exceptions and additional requirements as described in the following sections.
2.2. The references to the OBD threshold limits set out in paragraph 3.3.2 to Annex 11 of UN/ECE Regulation 83 shall be understood as references to the limits set out in section 2.3 of this Annex.
2.3. The reference fuels specified in paragraph 3.2 of Appendix 1 of Annex 11 of UN/ECE Regulation No 83 shall be understood as reference to the appropriate reference fuel specifications in Annex IX to this Regulation.
2.4. The reference to Annex 11 in paragraph 6.5.1.4 of Appendix 1 of Annex 11 of UN/ECE Regulation No 83 shall be understood as reference to Annex XI to this Regulation.
2.5. For vehicles approved to Euro 6 limit values contained in Table 2 of Annex 1 of Regulation (EC) No 715/2007, Section 6.5.3.1 of Appendix 1 of Annex 11 of UN/ECE Regulation 83 shall be replaced by:

‘For emissions-related diagnostics, the following standard shall be used as the on-board to off-board communications link:
ISO 15765-4 “Road vehicles — Diagnostics on Controller Area Network (CAN) — Part 4: Requirements for emissions-related systems” dated 10 January 2005’

3. IN-USE PERFORMANCE

3.1. General Requirements
3.1.1. Each monitor of the OBD system shall be executed at least once per driving cycle in which the monitoring conditions as specified in section 3.2 are met. Manufacturers may not use the calculated ratio (or any element thereof) or any other indication of monitor frequency as a monitoring condition for any monitor.
3.1.2. The in-use performance ratio (IUPR) of a specific monitor M of the OBD system referred to in Article 5(3) shall be:
IUPRM = NumeratorM/DenominatorM
3.1.3. Comparison of Numerator and Denominator gives an indication of how often a specific monitor is operating relative to vehicle operation. To ensure all manufacturers are tracking IUPRM in the same manner, detailed requirements are given for defining and incrementing these counters.
3.1.4. If, according to the requirements of this Annex, the vehicle is equipped with a specific monitor M, IUPRM shall be greater or equal to the following minimum values:
(i) 0,260 for secondary air system monitors and other cold start related monitors
(ii) 0,520 for evaporative emission purge control monitors
(iii) 0,336 for all other monitors
3.1.5. Vehicles shall comply with the requirements of section 3.1.4 for a mileage of at least 160 000 km. By way of derogation, vehicles type approved, registered, sold or entered into service before the relevant dates given in Article 10(4), (5) of Regulation (EC) No 715/2007, shall have an IUPRM greater or equal 0,1 for all monitors M. For new type approvals and new vehicles the monitor required by point 2.9 of this Annex shall have an IUPR greater or equal to 0,1 until three years after the dates specified in Article 10(4) and (5) of Regulation (EC) No 715/2007 respectively.
3.1.6. The requirements of this section are deemed to be met for a particular monitor M, if for all vehicles of a particular OBD family manufactured in a particular calendar year the following statistical conditions hold:
(a) The average IUPRM is equal or above the minimum value applicable to the monitor
(b) More than 50 % of all vehicles have an IUPRM equal or above the minimum value applicable to the monitor.
3.1.7. The manufacturer shall demonstrate to the approval authority and, upon request, to the Commission that these statistical conditions are satisfied for all monitors required to be reported by the OBD system according to point 3.6 of this Appendix not later than 18 months after the entry onto the market of the first vehicle type with IUPR in an OBD family and every 18 months thereafter. For this purpose, for OBD families consisting of more than 1 000 registrations in the Union, that are subject to sampling within the sampling period, the process described in Annex II shall be used without prejudice to the provisions of point 3.1.9 of this Appendix.
In addition to the requirements set out in Annex II and regardless of the result of the audit described in Section 2 of Annex II, the authority granting the approval shall apply the in-service conformity check for IUPR described in Appendix 1 to Annex II in an appropriate number of randomly determined cases. ‘ In an appropriate number of randomly determined cases ’ means, that this measure has a dissuasive effect on non-compliance with the requirements of Section 3 of this Annex or the provision of manipulated, false or non-representative data for the audit. If no special circumstances apply and can be demonstrated by the type-approval authorities, random application of the in-service conformity check to 5 % of the type approved OBD families shall be considered as sufficient for compliance with this requirement. For this purpose, type-approval authorities may find arrangements with the manufacturer for the reduction of double testing of a given OBD family as long as these arrangements do not harm the dissuasive effect of the type-approval authority’s own in-service conformity check on non-compliance with the requirements of Section 3 of this Annex. Data collected by Member States during surveillance testing programmes may be used for in-service conformity checks. Upon request, type-approval authorities shall provide data on the audits and random in-service conformity checks performed, including the methodology used for identifying those cases, which are made subject to the random in-service conformity check, to the Commission and other type-approval authorities.
3.1.8. For the entire test sample of vehicles the manufacturer must report to the relevant authorities all of the in-use performance data to be reported by the OBD system according to point 3.6 of this Appendix in conjunction with an identification of the vehicle being tested and the methodology used for the selection of the tested vehicles from the fleet. Upon request, the type-approval authority granting the approval shall make these data and the results of the statistical evaluation available to the Commission and other approval authorities.
3.1.9. Public authorities and their delegates may pursue further tests on vehicles or collect appropriate data recorded by vehicles to verify compliance with the requirements of this Annex.
3.1.10. Non-compliance with the requirements of point 3.1.6 established by tests described in points 3.1.7 or 3.1.9 shall be considered as an infringement subject to the penalties set out in Article 13 of Regulation (EC) No 715/2007. This reference does not limit the application of such penalties to other infringements of other provisions of Regulation (EC) No 715/2007 or this Regulation, which do no explicitly refer to Article 13 of Regulation (EC) No 715/2007.

3.2. NumeratorM
3.2.1. The numerator of a specific monitor is a counter measuring the number of times a vehicle has been operated such that all monitoring conditions necessary for the specific monitor to detect a malfunction in order to warn the driver, as they have been implemented by the manufacturer, have been encountered. The numerator shall not be incremented more than once per driving cycle, unless there is reasoned technical justification.

3.3. DenominatorM
3.3.1. The purpose of the denominator is to provide a counter indicating the number of vehicle driving events, taking into account special conditions for a specific monitor. The denominator shall be incremented at least once per driving cycle, if during this driving cycle such conditions are met and the general denominator is incremented as specified in section 3.5 unless the denominator is disabled according to section 3.7 of this Appendix.
3.3.2. In addition to the requirements of section 3.3.1:
(a) Secondary air system monitor denominator(s) shall be incremented if the commanded ‘on’ operation of the secondary air system occurs for a time greater than or equal to 10 seconds. For purposes of determining this commanded ‘on’ time, the OBD system may not include time during intrusive operation of the secondary air system solely for the purposes of monitoring;
(b) Denominators of monitors of systems only active during cold start shall be incremented if the component or strategy is commanded ‘on’ for a time greater than or equal to 10 seconds;
(c) The denominator(s) for monitors of Variable Valve Timing (VVT) and/or control systems shall be incremented if the component is commanded to function (e.g., commanded ‘on’, ‘open’, ‘closed’, ‘locked’, etc.) on two or more occasions during the driving cycle or for a time greater than or equal to 10 seconds, whichever occurs first;
(d) For the following monitors, the denominator(s) shall be incremented by one if, in addition to meeting the requirements of this section on at least one driving cycle, at least 800 cumulative kilometres of vehicle operation have been experienced since the last time the denominator was incremented:
(i) Diesel oxidation catalyst
(ii) Diesel particulate filter;
(e) Without prejudice to requirements for the increment of denominators of other monitors the denominators of monitors of the following components shall be incremented if and only if the driving cycle started with a cold start:
(i) liquid (oil, engine coolant, fuel, SCR reagent) temperature sensors;
(ii) clean air (ambient air, intake air, charge air, inlet manifold) temperature sensors;
(iii) exhaust (EGR recirculation/cooling, exhaust gas turbo-charging, catalyst) temperature sensors;
(f) The denominators of monitors of the boost pressure control system shall be incremented if the all of the following conditions are met:
(i) the general denominator conditions are fulfilled;
(ii) the boost pressure control system is active for a time greater than or equal to 15 seconds.
3.3.3. For hybrid vehicles, vehicles that employ alternative engine start hardware or strategies (e.g. integrated starter and generators), or alternative fuel vehicles (e.g. dedicated, bi-fuel, or dual-fuel applications), the manufacturer may request the approval of the approval authority to use alternative criteria to those set forth in this section for incrementing the denominator. In general, the approval authority shall not approve alternative criteria for vehicles that only employ engine shut off at or near idle/vehicle stop conditions. Approval by the approval authority of the alternative criteria shall be based on the equivalence of the alternative criteria to determine the amount of vehicle operation relative to the measure of conventional vehicle operation in accordance with the criteria in this section.

3.4. Ignition Cycle Counter
3.4.1. The ignition cycle counter indicates the number of ignition cycles a vehicle has experienced. The ignition cycle counter may not be incremented more than once per driving cycle.

3.5. General Denominator
3.5.1. The general denominator is a counter measuring the number of times a vehicle has been operated. It shall be incremented within 10 seconds, if and only if, the following criteria are satisfied on a single driving cycle:
Cumulative time since engine start is greater than or equal to 600 seconds while at an elevation of less than 2 440 m above sea level and at an ambient temperature of greater than or equal to – 7 °C.,
Cumulative vehicle operation at or above 40 km/h occurs for greater than or equal to 300 seconds while at an elevation of less than 2 440 m above sea level and at an ambient temperature of greater than or equal to – 7 °C.,
Continuous vehicle operation at idle (i.e. accelerator pedal released by driver and vehicle speed less than or equal to 1,6 km/h) for greater than or equal to 30 seconds while at an elevation of less than 2 440 m above sea level and at an ambient temperature of greater than or equal to – 7 °C.

3.6. Reporting and increasing counters
3.6.1. The OBD system shall report in accordance with the ISO 15031-5 specifications the ignition cycle counter and general denominator as well as separate numerators and denominators for the following monitors, if their presence on the vehicle is required by this Annex:
Catalysts (each bank to be reported separately),
Oxygen/exhaust gas sensors, including secondary oxygen sensors (each sensor to be reported separately),
Evaporative system,
EGR system,
VVT system,
Secondary air system,
Particulate filter,
NOx aftertreatment system (e.g. NOx adsorber, NOx reagent/catalyst system),
Boost pressure control system,
3.6.2. For specific components or systems that have multiple monitors, which are required to be reported by this point (e.g. oxygen sensor bank 1 may have multiple monitors for sensor response or other sensor characteristics), the OBD system shall separately track numerators and denominators for each of the specific monitors except those monitoring for short circuit or open circuit failures and report only the corresponding numerator and denominator for the specific monitor that has the lowest numerical ratio. If two or more specific monitors have identical ratios, the corresponding numerator and denominator for the specific monitor that has the highest denominator shall be reported for the specific component.
3.6.3. All counters, when incremented, shall be incremented by an integer of one.
3.6.4. The minimum value of each counter is 0, the maximum value shall not be less than 65 535, notwithstanding any other requirements on standardised storage and reporting of the OBD system.
3.6.5. If either the numerator or denominator for a specific monitor reaches its maximum value, both counters for that specific monitor shall be divided by two before being incremented again according to the provisions set in sections 3.2 and 3.3. If the ignition cycle counter or the general denominator reaches its maximum value, the respective counter shall change to zero at its next increment according to the provisions set in sections 3.4 and 3.5, respectively.
3.6.6. Each counter shall be reset to zero only when a non-volatile memory reset occurs (e.g. reprogramming event, etc.) or, if the numbers are stored in keep-alive memory (KAM), when KAM is lost due to an interruption in electrical power to the control module (e.g. battery disconnect, etc.).
3.6.7. The manufacturer shall take measures to ensure that the values of numerator and denominator can not be reset or modified, except in cases provided for explicitly in this section.

3.7. Disablement of Numerators and Denominators and of the General Denominator
3.7.1. Within 10 seconds of a malfunction being detected, which disables a monitor required to meet the monitoring conditions of this Annex (i.e. a pending or confirmed code is stored), the OBD system shall disable further incrementing of the corresponding numerator and denominator for each monitor that is disabled. When the malfunction is no longer detected (i.e., the pending code is erased through self-clearing or through a scan tool command), incrementing of all corresponding numerators and denominators shall resume within 10 seconds.
3.7.2. Within 10 seconds of the start of a power take-off operation (PTO) operation that disables a monitor required to meet the monitoring conditions of this Annex, the OBD system shall disable further incrementing of the corresponding numerator and denominator for each monitor that is disabled. When the PTO operation ends, incrementing of all corresponding numerators and denominators shall resume within 10 seconds.
3.7.3. The OBD system shall disable further incrementing of the numerator and denominator of a specific monitor within 10 seconds, if a malfunction of any component used to determine the criteria within the definition of the specific monitor’s denominator (i.e. vehicle speed, ambient temperature, elevation, idle operation, engine cold start, or time of operation) has been detected and the corresponding pending fault code has been stored. Incrementing of the numerator and denominator shall resume within 10 seconds when the malfunction is no longer present (e.g. pending code erased through self-clearing or by a scan tool command).
3.7.4. The OBD system shall disable further incrementing of the general denominator within 10 seconds, if a malfunction has been detected of any component used to determine whether the criteria in section 3.5 are satisfied (i.e. vehicle speed, ambient temperature, elevation, idle operation, or time of operation) and the corresponding pending fault code has been stored. The general denominator may not be disabled from incrementing for any other condition. Incrementing of the general denominator shall resume within 10 seconds when the malfunction is no longer present (e.g., pending code erased through self-clearing or by a scan tool command).

The manufacturer shall be consulted on the choice of the vehicles in the sample and be allowed to attend the confirmatory checks of the vehicles.
3.3. The manufacturer shall be authorized, under the supervision of the approval authority, to carry out checks, even of a destructive nature, on those vehicles with emission levels in excess of the limit values with a view to establishing possible causes of deterioration which cannot be attributed to the manufacturer himself. Where the results of the checks confirm such causes, those test results are excluded from the conformity check.
3.4. Where the approval authority is not satisfied with the results of the tests in accordance with the criteria defined in Appendix 2, the remedial measures referred to to in Article 11(2) and in Annex X to Directive 70/156/EEC are extended to vehicles in service belonging to the same vehicle type which are likely to be affected with the same defects in accordance with section 6 of Appendix 1.
The plan of remedial measures presented by the manufacturer shall be approved by the approval authority. The manufacturer is responsible for the execution of the remedial plan as approved.
The approval authority shall notify its decision to all Member States within 30 days. The Member States may require that the same plan of remedial measures be applied to all vehicles of the same type registered in their territory.
3.5. If a Member State has established that a vehicle type does not conform to the applicable requirements of Appendix 1 to this Annex, it shall notify without delay the Member State which granted the original type-approval in accordance with the requirements of Article 11(3) of Directive 70/156/EEC.
After that notification and subject to the provision of Article 11(6) of Directive 70/156/EEC, the competent authority of the Member State which granted the original type-approval shall inform the manufacturer that a vehicle type fails to satisfy the requirements of these provisions and that certain measures are expected of the manufacturer. The manufacturer shall submit to the authority, within two months after this notification, a plan of measures to overcome the defects, the substance of which should correspond to the requirements of sections 6.1 to 6,8 of Appendix 1. The competent authority which granted the original type-approval shall, within two months, consult the manufacturer in order to secure agreement on a plan of measures and on carrying out the plan. If the competent authority which granted the original type-approval establishes that no agreement can be reached, the procedure pursuant to Article 11(3) and (4) of Directive 70/156/EEC shall be initiated.

Appendix 1 In-service conformity check

1. INTRODUCTION
This Appendix sets out the criteria for the in-service conformity control of vehicles type-approved under Directive 70/220/EEC.

2. SELECTION CRITERIA
The criteria for acceptance of a selected vehicle are defined in sections 2.1 to 2.8. Information shall be collected by the approval authority by vehicle examination and an interview with the owner/driver.
2.1. The vehicle shall belong to a vehicle type that is type-approved under Directive 70/220/EEC and covered by a certificate of conformity in accordance with Directive 70/156/EEC. The vehicle shall be registered and used in the European Community.
2.2. The vehicle shall have been in service for at least 15 000 km or 6 months, whichever is the later, and for no more than 100 000 km or 5 years, whichever is the sooner.
2.3. There shall be a maintenance record to show that the vehicle has been properly maintained, e. g. has been serviced in accordance with the manufacturer’s recommendations.
2.4. The vehicle shall exhibit no indications of abuse (e. g. racing, overloading, misfuelling, or other misuse), or other factors (e. g. tampering) that could affect emission performance. In the case of vehicles fitted with an OBD system, the fault code and mileage information stored in the computer are taken into account. A vehicle shall not be selected for testing if the information stored in the computer shows that the vehicle has operated after a fault code was stored and a relatively prompt repair was not carried out.
2.5. There shall have been no unauthorized major repair to the engine or major repair of the vehicle.
2.6. The lead content and sulphur content of a fuel sample from the vehicle tank shall meet the applicable standards laid down in Directive 98/70/EC of the European Parliament and of the Council and there shall be no evidence of misfuelling. Checks may be done in the tailpipe etc.
OJ L 350, 28.12.1998, p. 58.
2.7. There shall be no indication of any problem that might jeopardize the safety of laboratory personnel.
2.8. All anti-pollution system components on the vehicle shall be in conformity with the applicable type-approval.

3. DIAGNOSIS AND MAINTENANCE
Diagnosis and any normal maintenance necessary shall be performed on vehicles accepted for testing, prior to measuring exhaust emissions, in accordance with the procedure laid down in section 3.1 to 3.7.
3.1. The following checks shall be carried out: checks on air filter, all drive belts, all fluid levels, radiator cap, all vacuum hoses and electrical wiring related to the antipollution system for integrity; checks on ignition, fuel metering and pollution control device components for maladjustments and/or tampering. All discrepancies shall be recorded.
3.2. The OBD system shall be checked for proper functioning. Any malfunction indications in the OBD memory shall be recorded and the requisite repairs shall be carried out. If the OBD malfunction indicator registers a malfunction during a preconditioning cycle, the fault may be identified and repaired. The test may be re-run and the results of that repaired vehicle used.
3.3. The ignition system shall be checked and defective components replaced, for example spark plugs, cables, etc.
3.4. The compression shall be checked. If the result is unsatisfactory the vehicle shall be rejected.
3.5. The engine parameters shall be checked to the manufacturer’s specifications and adjusted if necessary.

ANNEX XVI REQUIREMENTS FOR VEHICLES THAT USE A REAGENT FOR THE EXHAUST AFTERTREATMENT SYSTEM

1. INTRODUCTION
This Annex sets out the requirements for vehicles that rely on the use of a reagent for the aftertreatment system in order to reduce emissions.

2. REAGENT INDICATION
2.1. The vehicle shall include a specific indicator on the dashboard that informs the driver of low levels of reagent in the reagent storage tank and of when the reagent tank becomes empty.

3. DRIVER WARNING SYSTEM
3.1. The vehicle shall include a warning system consisting of visual alarms that informs the driver when the reagent level is low, that the tank soon needs to be refilled, or the reagent is not of a quality specified by the manufacturer. The warning system may also include an audible component to alert the driver.
3.2. The warning system shall escalate in intensity as the reagent approaches empty. It shall culminate in a driver notification that can not be easily defeated or ignored. It shall not be possible to turn off the system until the reagent has been replenished.
3.3. The visual warning shall display a message indicating a low level of reagent. The warning shall not be the same as the warning used for the purposes of OBD or other engine maintenance. The warning shall be sufficiently clear for the driver to understand that the reagent level is low (e.g. ‘urea level low’, ‘AdBlue level low’, or ‘reagent low’).
3.4. The warning system does not initially need to be continuously activated, however the warning shall escalate so that it becomes continuous as the level of the reagent approaches the point where the driver inducement system in Section 8 comes into effect. An explicit warning shall be displayed (e.g. ‘fill up urea’, ‘fill up AdBlue’, or ‘fill up reagent’). The continuous warning system may be temporarily interrupted by other warning signals providing important safety related messages.
3.5. The warning system shall activate at a distance equivalent to a driving range of at least 2 400 km in advance to the reagent tank becoming empty.

4. IDENTIFICATION OF INCORRECT REAGENT
4.1. The vehicle shall include a means of determining that a reagent corresponding to the characteristics declared by the manufacturer and recorded in Appendix 3 to Annex I to this Regulation is present on the vehicle.
4.2. If the reagent in the storage tank does not correspond to the minimum requirements declared by the manufacturer the driver warning system in section 3 shall be activated and shall display a message indicating an appropriate warning (e.g. ‘incorrect urea detected’, ‘incorrect AdBlue detected’, or ‘incorrect reagent detected’). If the reagent quality is not rectified within 50 km of the activation of the warning system then the driver inducement requirements of section 8 shall apply.

5. REAGENT CONSUMPTION MONITORING
5.1. The vehicle shall include a means of determining reagent consumption and providing off-board access to consumption information.
5.2. Average reagent consumption and average demanded reagent consumption by the engine system shall be available via the serial port of the standard diagnostic connector. Data shall be available over the previous complete 2 400 km period of vehicle operation.
5.3. In order to monitor reagent consumption, at least the following parameters within the vehicle shall be monitored:
(a) the level of reagent in the on-vehicle storage tank;
(b) the flow of reagent or injection of reagent as close as technically possible to the point of injection into an exhaust aftertreatment system.
5.4. A deviation of more than 50 % between the average reagent consumption and the average demanded reagent consumption by the engine system over a period of 30 minutes of vehicle operation, shall result in the activation of the driver warning system in section 3, which shall display a message indicating an appropriate warning (e.g. ‘urea dosing malfunction’, ‘AdBlue dosing malfunction’, or ‘reagent dosing malfunction’). If the reagent consumption is not rectified within 50 km of the activation of the warning system then the driver inducement requirements of section 8 shall apply.
5.5. In the case of interruption in reagent dosing activity the driver warning system as referred to in section 3 shall be activated, which shall display a message indicating an appropriate warning. This activation shall not be required where the interruption is demanded by the engine ECU because the vehicle operating conditions are such that the vehicle's emission performance does not require reagent dosing, provided that the manufacturer has clearly informed the approval authority when such operating conditions apply. If the reagent dosing is not rectified within 50 km of the activation of the warning system then the driver inducement requirements of section 8 shall apply.

6. MONITORING NOx EMISSIONS
6.1. As an alternative to the monitoring requirements in section 4 and 5 manufacturers may use exhaust gas sensors directly to sense excess NOx levels in the exhaust.
6.2. The manufacturer shall demonstrate that use of the sensors referred to in point 6.1 and any other sensors on the vehicle, results in the activation of the driver warning system as referred to in point 3, the display of a message indicating an appropriate warning (e.g. ‘ emissions too high — check urea ’ , ‘ emissions too high — check AdBlue ’ , ‘ emissions too high — check reagent ’ ), and the driver inducement system as referred to in point 8.3, when the situations referred to in points 4.2, 5.4 or 5.5 occur.
For the purposes of this point these situations are presumed to occur:
in the case of vehicles approved to the Euro 5 emission limits of Table 1 of Annex I to Regulation (EC) No 715/2007, if the applicable NO x emission limit of that table multiplied by a factor of 1,5, is exceeded,
in the case of vehicles approved to the Euro 6 emission limits of Table 2 of Annex I to Regulation (EC) No 715/2007, if the applicable NO x OBD threshold limit of the tables set out in points 2.3.2, 2.3.3 or 2.3.4 of Annex XI is exceeded.
NO x emissions during the test to demonstrate compliance with these requirements shall be no more than 20 % higher than the values referred to in the second paragraph.

7. STORAGE OF FAILURE INFORMATION
7.1. Where reference is made to this point, non-erasable Parameter Identifiers (PID) shall be stored identifying the reason for and the distance travelled by the vehicle during the inducement system activation. The vehicle shall retain a record of the PID for at least 800 days or 30 000 km of vehicle operation. The PID shall be made available via the serial port of a standard diagnostic connector upon request of a generic scan tool according to the provisions of point 6.5.3.1 of Appendix 1 to Annex 11 to UN/ECE Regulation No 83 and point 2.5 of Appendix 1 to Annex XI to this Regulation. From the dates referred to in Article 17, the information stored in the PID shall be linked to the period of cumulated vehicle operation, during which it has occurred, with an accuracy of not less than 300 days or 10 000 km.
7.2. Malfunctions in the reagent dosing system attributed to technical failures (e.g. mechanical or electrical faults) shall also be subject to the OBD requirements in Annex XI.

8. DRIVER INDUCEMENT SYSTEM
8.1. The vehicle shall include a driver inducement system to ensure that the vehicle operates with a functioning emissions control system at all times. The inducement system shall be designed so as to ensure that the vehicle can not operate with an empty reagent tank.
8.2. The inducement system shall activate at the latest when the level of reagent in the tank reaches a level equivalent to the average driving range of the vehicle with a complete tank of fuel. The system shall also activate when the failures in sections 4, 5 or 6 have occurred, depending on the NOx monitoring approach. The detection of an empty reagent tank and the failures mentioned in sections 4, 5 or 6 shall result in the failure information storage requirements of section 7 coming into effect.
8.3. The manufacturer shall select which type of inducement system to install. The options for a system are described in following points 8.3.1, 8.3.2, 8.3.3 and 8.3.4.
8.3.1. A ‘no engine restart after countdown’ approach allows a countdown of restarts or distance remaining once the inducement system activates. Engine starts initiated by the vehicle control system, such as start-stop systems, are not included in this countdown. Engine restarts shall be prevented immediately after the reagent tank becomes empty or a distance equivalent to a complete tank of fuel has been exceeded since the activation of the inducement system, whichever occurs earlier.
8.3.2. A ‘no start after refuelling’ system results in a vehicle being unable to start after re-fuelling if the inducement system has activated.
8.3.3. A ‘fuel-lockout’ approach prevents the vehicle from being refuelled by locking the fuel filler system after the inducement system activates. The lockout system shall be robust to prevent it being tampered with.
8.3.4. A ‘performance restriction’ approach restricts the speed of the vehicle after the inducement system activates. The level of speed limitation shall be noticeable to the driver and significantly reduce the maximum speed of the vehicle. Such limitation shall enter into operation gradually or after an engine start. Shortly before engine restarts are prevented, the speed of the vehicle shall not exceed 50 km/h. Engine restarts shall be prevented immediately after the reagent tank becomes empty or a distance equivalent to a complete tank of fuel has been exceeded since the activation of inducement system, whichever occurs earlier.
8.4. Once the inducement system has fully activated and disabled the vehicle, the inducement system shall only be deactivated if the quantity of reagent added to the vehicle is equivalent to 2 400 km average driving range, or the failures specified in sections 4, 5, or 6 have been rectified. After a repair has been carried out to correct a fault where the OBD system has been triggered under point 7.2, the inducement system may be reinitialised via the OBD serial port (e.g. by a generic scan tool) to enable the vehicle to be restarted for self-diagnosis purposes. The vehicle shall operate for a maximum of 50 km to enable the success of the repair to be validated. The inducement system shall be fully reactivated if the fault persists after this validation.
8.5. The driver warning system referred to in section 3 shall display a message indicating clearly:
(a) the number of remaining restarts and/or the remaining distance; and
(b) the conditions under which the vehicle can be restarted.
8.6. The driver inducement system shall be deactivated when the conditions for its activation have ceased to exist. The driver inducement system shall not be automatically deactivated without the reason for its activation having been remedied.
8.7. Detailed written information fully describing the functional operation characteristics of the driver inducement system shall be provided to the approval authority at the time of approval.
8.8. As part of the application for type-approval under this Regulation, the manufacturer shall demonstrate the operation of the driver warning and inducement systems.

9. INFORMATION REQUIREMENTS
9.1. The manufacturer shall provide all owners of new vehicles written information about the emission control system. This information shall state that if the vehicle emission control system is not functioning correctly, the driver shall be informed of a problem by the driver warning system and that the driver inducement system shall consequentially result in the vehicle being unable to start.
9.2. The instructions shall indicate requirements for the proper use and maintenance of vehicles, including the proper use of consumable reagents.
9.3. The instructions shall specify if consumable reagents have to be refilled by the vehicle operator between normal maintenance intervals. They shall indicate how the driver should refill the reagent tank. The information shall also indicate a likely rate of reagent consumption for that type of vehicle and how often it should be replenished.
9.4. The instructions shall specify that use of, and refilling of, a required reagent of the correct specifications is mandatory for the vehicle to comply with the certificate of conformity issued for that vehicle type.
9.5. The instructions shall state that it may be a criminal offence to use a vehicle that does not consume any reagent if it is required for the reduction of emissions.
9.6. The instructions shall explain how the warning system and driver inducement systems work. In addition, the consequences of ignoring the warning system and not replenishing the reagent shall be explained.

10. OPERATING CONDITIONS OF THE AFTERTREATMENT SYSTEM
Manufacturers shall ensure that the emission control system retains its emission control function during all ambient conditions regularly found in the European Union, especially at low ambient temperatures. This includes taking measures to prevent the complete freezing of the reagent during parking times of up to 7 days at 258 K (– 15 °C) with the reagent tank 50 % full. If the reagent has frozen, the manufacturer shall ensure that reagent shall be available for use within 20 minutes of the vehicle starting at 258 K (– 15 °C) measured inside the reagent tank, so as to ensure correct operation of the emission control system.

ANNEX XVII AMENDMENTS TO REGULATION (EC) No 715/2007
Regulation (EC) No 715/2007 is amended as follows:
1. The following paragraph 6 shall be added to Article 10:
