Commission Regulation (EU) 2018/1832

of 5 November 2018

amending Directive 2007/46/EC of the European Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) 2017/1151 for the purpose of improving the emission type approval tests and procedures for light passenger and commercial vehicles, including those for in-service conformity and real-driving emissions and introducing devices for monitoring the consumption of fuel and electric energy

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EC) No 715/2007 of the European Parliament and of the Council of 20 June 2007 on type approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information(1), and in particular Articles 5(3) and 14(3) thereof,

Having regard to Directive 2007/46/EC of the European Parliament and of the Council of 5 September 2007 establishing a framework for the approval of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles (Framework Directive)(2), and in particular Article 39(2) thereof,

Whereas:

(1) Regulation (EC) No 715/2007 is a separate act under the type-approval procedure laid down by Directive 2007/46/EC. It requires new light passenger and commercial vehicles to comply with certain emission limits and lays down additional requirements on access to vehicle repair and maintenance information. The specific technical provisions necessary to implement that Regulation are contained in Commission Regulation (EU) 2017/1151(3), which replaces and repeals Commission Regulation (EC) No 692/2008(4).

(2) Some of the effects of Commission Regulation (EC) No 692/2008 remain until it is repealed as from 1 January 2022. However, it is necessary to clarify that such effects include the possibility to request extensions of existing type-approvals granted under this Regulation.

(3) By Regulation (EU) 2017/1151, a new regulatory test procedure implementing the Worldwide Harmonised Light Vehicles Test Procedure (WLTP) was introduced into Union legislation. The WLTP contains stricter and more detailed conditions for the execution of the emissions tests at type approval.

(4) In addition, by Commission Regulations (EU) 2016/427(5), (EU) 2016/646(6) and (EU) 2017/1154(7) a new methodology for testing vehicle emissions in real-driving conditions, the RDE test procedure, was introduced.

(5) In order for the WLTP test to be possible, some margin of tolerance is necessary. However, the test tolerance should not be exploited to obtain results different from those associated with the execution of the test at set-point conditions. Therefore, in order to provide a level playing field among different vehicle manufacturers and to ensure that the measured CO₂ and fuel consumption values are more in line with real life, a method to normalise the impact of specific test tolerances on CO₂ and fuel consumption test results should be introduced.

(6) The fuel and/or electric energy consumption values resulting from the regulatory laboratory test procedures should be complemented by information on the vehicles' average real-world consumption when used on the road. Such information, once anonymised, collected and aggregated, is essential for assessing that the regulatory test procedures adequately reflect the average real world CO₂ emissions as well as the fuel and/or electric energy consumed. Moreover, the availability at the vehicle of instantaneous fuel consumption information should facilitate on-road testing.

(7) To ensure a timely assessment of the representativeness of the new regulatory test procedures, in particular for vehicles with large market shares, the scope of the new requirements for on-board fuel consumption monitoring should be in a first instance limited to conventional and hybrid vehicles running on liquid fuels and to plug-in hybrid vehicles, as these are to-date the only powertrains covered by corresponding technical standards.

(8) The quantity of fuel and/or electric energy used is already being determined and stored on board of most new vehicles; however, the devices presently used to monitor this information are not subject to standardised requirements. In order to ensure that the data provided by these devices are accessible and may serve as a harmonised basis for a comparison between different vehicle categories and manufacturers, basic type-approval requirements with regard to the devices should be laid down.

(9) Regulation (EU) 2016/646 introduced the requirement for the manufacturers to declare the use of auxiliary emission strategies. In addition, Regulation (EU) 2017/1154 increased the supervision of emission strategies by the type approval authorities. However, the application of those requirements has highlighted the need to harmonise the application of the rules on auxiliary emission strategies by the different type approval authorities. Therefore it is appropriate to lay down a common format for the extended documentation package and a common methodology for the assessment of auxiliary emission strategies.

(10) The decision to allow access, if requested, to the manufacturer's extended documentation package should be left to the national authorities and therefore the confidentiality clause linked to this document should be deleted from Regulation (EU) 2017/1151. This deletion should be without prejudice to the uniform application of the legislation throughout the Union, as well as the possibility for all parties to access all relevant information for conducting RDE testing.

(11) After the introduction of the RDE tests at the stage of type approval, it is now necessary to update the rules on in-service conformity checks in order to ensure that the real driving emissions are also effectively limited during the normal life of the vehicles under normal conditions of use.

(12) The application of the new RDE during in-service conformity checks will require more resources for the performance of the in-service conformity testing of a vehicle and the evaluation of its results. In order to balance the need to perform effective in-service conformity tests with the increased testing burden, the maximum number of vehicles in a statistical sample and the pass and fail criteria for the sample applicable to all in-service conformity testing should be adapted.

(13) In-service conformity checks currently cover only pollutant emissions measured through the Type 1 test. However, in order to ensure that the requirements of Regulation (EC) No 715/2007 are met, they should be extended to tailpipe and evaporative emissions. Therefore, Type 4 and Type 6 tests should be introduced for the purposes of in-service conformity tests. Due to the cost and complexity of such tests, they should remain optional.

(14) A review of the current in-service conformity tests, performed by the manufacturers, revealed that very few fails were reported to type approval authorities although recall campaigns and other voluntary actions related to emissions were implemented by the manufacturers. Therefore, it is necessary to introduce more transparency and control in the in-service conformity checks.

(15) In order to control the in-service conformity process more effectively, type approval authorities should be responsible for performing tests and checks on a percentage of the approved vehicle types each year.

(16) In order to facilitate the information flows generated by in-service conformity testing, as well as to assist type-approval authorities in the decision making process, an electronic platform should be developed by the Commission.

(17) In order to improve the vehicle selection process for the testing by type-approval authorities, information is needed that could identify potential problems and vehicle types with high emissions. Remote sensing, simplified on-board emissions monitoring systems (SEMS) and testing with portable emission measurement systems (PEMS) should be recognised as valid tools for providing information to the type-approval authorities that can guide the selection of vehicles to test.

(18) Ensuring the quality of the in-service conformity tests is essential. It is therefore necessary to lay down the rules on the accreditation of testing laboratories.

(19) In order to allow testing, all relevant information needs to be publicly accessible. In addition, some of the information needed for the performance of in-service conformity checks should be easily available and should therefore be indicated in the certificate of conformity.

(20) In order to increase the transparency of the in-service conformity process, type approval authorities should be required to publish an annual report with the results of their in-service conformity checks.

(21) The methodologies prescribed in order to ensure that only trips made under normal conditions be considered valid RDE tests led to too many invalid tests and should therefore be reviewed and simplified.

(22) A review of the methodologies for the evaluation of the pollutant emissions of a valid trip showed that the results of the two methods currently allowed are not consistent. A new simple and transparent methodology should therefore be laid down. The evaluation factors used in the new methodology should be kept under constant assessment by the Commission in order to reflect the actual state of the technology.

(23) The use of plug-in hybrids, which are used partly in electric mode and partly with the internal combustion engine, should be duly taken into account for the purposes of RDE testing and therefore the calculated RDE emissions should reflect that advantage.

(24) A new evaporative emissions test procedure has been developed at the level of the United Nations Economic Commission for Europe (UN/ECE) which takes into account the technological progress in the control of evaporative emissions from petrol (gasoline) vehicles, adapts that procedure to the WLTP test procedure and introduces new provisions for sealed tanks. It is therefore appropriate to update the current Union rules on evaporative emissions tests to reflect the changes at the level of the UN/ECE.

(25) Also under the auspices of the UN/ECE, the WLTP test procedure has been further improved and complemented with a series of new elements, including alternative ways to measure the road load parameters of a vehicle, more clear provisions for bi-fuel vehicles, improvements of the CO₂ interpolation method, updates related to dual-axis dynamometer requirements and tyre rolling resistances. Those new developments should now be incorporated into Union legislation.

(26) The practical experience with the application of the WLTP since its mandatory introduction for new vehicle types in the Union on 1 September 2017 has shown that this procedure should be further adapted to the Union type-approval system, in particular as regards the information to be included in the relevant documentation.

(27) The changes in the type-approval documentation resulting from the amendments in this Regulation need to be reflected also in the certificate of conformity and the whole vehicle type-approval documentation in Directive 2007/46/EC.

(28) It is therefore appropriate to amend Regulation (EU) 2017/1151, Regulation (EC) No 692/2008 and Directive 2007/46/EC accordingly.

(29) The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee — Motor Vehicles,

The following Appendix 3b is inserted:

‘Appendix 3bU.K. Methodology for the assessment of AES

The assessment of the AES by the type-approval authority shall include at least the following verifications:

(1)

The increase of emissions induced by the AES shall be kept at the lowest possible level:

(a)

The increase of total emissions when using an AES shall be kept at the lowest possible level throughout the normal use and life of the vehicles;

(b)

Whenever a technology or design that would allow for improved emission control is available on the market at the time of the AES preliminary assessment it shall be used with no unjustified modulation

(2)

When used to justify an AES, the risk of sudden and irreparable damage to the “propulsion energy converter and the drivetrain”, as defined in Mutual Resolution No. 2 (M.R.2) of the 1958 and 1998 Agreements of UNECE containing Vehicle Propulsion System Definitions(9), shall be appropriately demonstrated and documented, including the following information:

(a)

Proof of catastrophic (i.e. sudden and irreparable) engine damage shall be provided by the manufacturer, along with a risk assessment which includes an evaluation of the likelihood of the risk occurring and severity of the possible consequences, including results of tests carried out to this effect;

(b)

When a technology or design is available on the market at the time of the AES application that eliminates or reduces that risk, it shall be used to the largest extent technically possible (i.e. with no unjustified modulation);

(c)

Durability and the long-term protection of the engine or components of the emission control system from wear and malfunctioning shall not be considered an acceptable reason to grant an exemption from the defeat device prohibition.

(3)

An adequate technical description shall document why it is necessary to use an AES for the safe operation of the vehicle:

(a)

Proof of an increased risk to the safe operation of the vehicle should be provided by the manufacturer along with a risk assessment which includes an evaluation of the likelihood of the risk occurring and severity of the possible consequences, including results of tests carried out to this effect;

(b)

When a different technology or design is available on the market at the time of the AES application that would allow for lowering the safety risk, it shall be used to the largest extent technically possible (i.e. with no unjustified modulation).

(4)

An adequate technical description shall document why it is necessary to use an AES during engine start:

(a)

Proof of the need to use an AES during engine start shall be provided by the manufacturer along with a risk assessment which includes an evaluation of the likelihood of the risk occurring and severity of the possible consequences, including results of tests carried out to this effect;

(b)

Where a different technology or design is available on the market at the time of the AES application that would allow for improved emission control upon engine start, it shall be used to the largest extent technically possible.’

1.Introduction

This Part shall apply to M and N1 class I vehicles based on types approved after 1 January 2019 and to all vehicles registered after 1 September 2019 and to N1 classes II and III and N2 vehicles based on types approved after 1 September 2019 and registered after 1 September 2020.

It sets out the in-service conformity (ISC) requirements for checking compliance against the emission limits for tailpipe (including low temperature) and evaporative emissions throughout the normal life of the vehicle up to five years or 100 000 km, whichever is sooner.

2.Process description

Figure B.1 Illustration of the in-service conformity process (where GTAA refers to the granting type approval authority and OEM refers to the manufacturer)

3.ISC family definition

An ISC family shall be composed of the following vehicles:

(a)

For tailpipe emissions (Type 1 and Type 6 tests), the vehicles covered by the PEMS test family, as described in Appendix 7 of Annex IIIA,

(b)

For evaporative emissions (Type 4 test), the vehicles included in the evaporative emission family, as described in Point 5.5 of Annex VI.

4.Information gathering and initial risk assessment

The granting type approval authority shall gather all relevant information on possible emission non-compliances relevant for deciding which ISC families to check in a particular year. The granting type-approval authority shall take into account in particular information indicating vehicle types with high emissions in real driving conditions. That information shall be obtained through the use of appropriate methods, which may include remote sensing, simplified on-board emissions monitoring systems (SEMS) and testing with PEMS. The number and importance of exceedances observed during such testing may be used to prioritise ISC testing.

As part of the information provided for the ISC checks, each manufacturer shall report to the granting type approval authority on emission-related warranty claims, and any emission-related warranty repair works performed or recorded during servicing, in accordance with a format agreed between the granting type approval authority and the manufacturer at type approval. The information shall detail the frequency and nature of faults for emissions-related components and systems by ISC family. The reports shall be filed at least once a year for each vehicle ISC family for the duration of the period during which in-service conformity checks are to be performed in accordance with Article 9(3).

On the basis of the information referred to in the first and second paragraphs, the granting type approval authority shall make an initial assessment of the risk of an ISC family to not comply with the in-service conformity rules and on that basis shall take a decision on which families to test and which types of tests to perform under the ISC provisions. Additionally, the granting type approval authority may randomly choose ISC families to test.

5.ISC testing

The manufacturer shall perform ISC testing for tailpipe emissions comprising at least the Type 1 test for all ISC families. The manufacturer may also perform RDE, Type 4 and Type 6 tests for all or part of the ISC families. The manufacturer shall report to the granting type approval authority all results of the ISC testing using the Electronic Platform for in-service conformity described in point 5.9.

The granting type approval authority shall check an appropriate number of ISC families each year, as set out in point 5.4. The granting type approval authority shall include all results of the ISC testing in the Electronic Platform for in-service conformity described in point 5.9.

Accredited laboratories or technical services may perform checks on any number of ISC families each year. The accredited laboratories or technical services shall report to the granting type approval authority all results of the ISC testing using the Electronic Platform for in-service conformity described in point 5.9.

5.1.Quality assurance of testing

Inspection bodies and laboratories performing ISC checks, that are not a designated technical service, shall be accredited according to EN ISO/IEC 17020:2012 for the ISC procedure. Laboratories performing ISC tests and which are not designated technical services within the meaning of Article 41 of Directive 2007/46, may only undertake ISC testing if they are accredited according to EN ISO/IEC 17025:2017.

The granting type approval authority shall annually audit the ISC checks performed by the manufacturer. The granting type approval authority may also audit the ISC checks performed by accredited laboratories and technical services. The audit shall be based on the information provided by the manufacturers, accredited laboratory or technical service which shall include at least the detailed ISC report in accordance with Appendix 3. The granting type approval authority may require the manufacturers, accredited laboratories or technical services to provide additional information.

5.2.Disclosure of tests results by accredited laboratories and technical services

The granting type approval authority shall communicate the results of the compliance assessment and remedial measures for a particular ISC family to the accredited laboratories or technical services which provided test results for that family as soon as they become available.

The results of the tests, including the detailed data for all vehicles tested, may only be disclosed to the public after the publication by the granting type approval authority of the annual report or the results of an individual ISC procedure or after the closure of the statistical procedure (see point 5.10.) without a result. If the results of the ISC tests are published, reference shall be made to the annual report by the granting type approval authority which included them.

5.3.Types of tests

ISC testing shall only be performed on vehicles selected in accordance with Appendix 1.

ISC testing with the Type 1 test shall be performed in accordance with Annex XXI.

ISC testing with the RDE tests shall be performed in accordance with Annex IIIA, Type 4 tests shall be performed in accordance with Appendix 2 to this Annex and Type 6 tests shall be performed in accordance with Annex VIII.

5.4.Frequency and scope of ISC testing

The time period between commencing two in-service conformity checks by the manufacturer for a given ISC family shall not exceed 24 months.

The frequency of ISC testing performed by the granting type approval authority shall be based on a risk assessment methodology consistent with the international standard ISO 31000:2018 — Risk Management — Principles and guidelines which shall include the results of the initial assessment made according to point 4.

As of 1 January 2020, granting type approval authorities shall perform the Type 1 and RDE tests on a minimum of 5 % of the ISC families per manufacturer per year or at least two ISC families per manufacturer per year, where available. The requirement for testing a minimum of 5 % or at least two ISC families per manufacturer per year shall not apply to small volume manufacturers. The granting type approval authority shall ensure the widest possible coverage of ISC families and vehicle age in a particular in-service conformity family in order to ensure compliance according to Article 8, paragraph 3. The granting type approval authority shall complete the statistical procedure for each ISC family it has started within 12 months.

Type 4 or Type 6 ISC tests shall have no minimum frequency requirements.

5.5.Funding for ISC testing by the granting type approval authorities

The granting type approval authority shall ensure that sufficient resources are available to cover the costs for in-service conformity testing. Without prejudice to national law, those costs shall be recovered by fees that can be levied on the manufacturer by the granting type approval authority. Such fees shall cover ISC testing of up to 5 % of the in-service conformity families per manufacturer per year or at least two ISC families per manufacturer per year.

5.6.Testing plan

When performing RDE testing for ISC, the granting type approval authority shall draft a testing plan. That plan shall include testing to check ISC compliance under a wide range of conditions in accordance with Annex IIIA.

5.7.Selection of vehicles for ISC testing

The information gathered shall be sufficiently comprehensive to ensure that in-service performance can be assessed for vehicles that are properly maintained and used. The tables in Appendix 1 shall be used to decide whether the vehicle can be selected for the purposes of ISC testing. During the check against the tables in Appendix 1, some vehicles may be declared as faulty and not tested during ISC, when there is evidence that parts of the emission control system were damaged.

The same vehicle may be used to perform and establish reports from more than one type of tests (Type 1, RDE, Type 4, Type 6) but only the first valid test of each type shall be taken into account for the statistical procedure.

5.7.1.General requirements

The vehicle shall belong to an ISC family as described in point 3 and shall comply with the checks set out in the table in Appendix 1. It shall be registered in the Union and have been driven in the Union for at least 90 % of its driving time. The emissions testing may be done in a different geographical region from that where the vehicles have been selected.

The vehicles selected shall be accompanied by a maintenance record which shows that the vehicle has been properly maintained and has been serviced in accordance with the manufacturer's recommendations with only original parts used for the replacement of emissions related parts.

Vehicles exhibiting indications of abuse, improper use that could affect its emissions performance, tampering or conditions that may lead to unsafe operation shall be excluded from ISC.

The vehicles shall not have undergone aerodynamic modifications that cannot be removed prior to testing.

A vehicle shall be excluded from ISC testing if the information stored in the on-board computer shows that the vehicle was operated after a fault code was displayed and a repair was not carried out in accordance with manufacturer specifications.

A vehicle shall be excluded from ISC testing if the fuel from the vehicle tank does not meet the applicable standards laid down in Directive 98/70/EC of the European Parliament and of the Council(10) or if there is evidence or record of fuelling with the wrong type of fuel.

5.7.2.Vehicle Examination and Maintenance

Diagnosis of faults and any normal maintenance necessary in accordance with Appendix 1 shall be performed on vehicles accepted for testing, prior to or after proceeding with ISC testing.

The following checks shall be carried out: OBD checks (performed before or after the test), visual checks for lit malfunction indicator lamps, checks on air filter, all drive belts, all fluid levels, radiator and fuel filler cap, all vacuum and fuel system hoses and electrical wiring related to the after-treatment system for integrity; checks on ignition, fuel metering and pollution control device components for maladjustments and/or tampering.

If the vehicle is within 800 km of a scheduled maintenance service, that service shall be performed.

The window washer fluid shall be removed before the Type 4 test and replaced with hot water.

A fuel sample shall be collected and kept in accordance with the requirements of Annex IIIA for further analysis in case of fail.

All faults shall be recorded. When the fault is on the pollution control devices then the vehicle shall be reported as faulty and not be used further for testing, but the fault shall be taken into account for the purposes of the compliance assessment performed in accordance with point 6.1.

5.8.Sample size

When manufacturers apply the statistical procedure set out in point 5.10 for the Type 1 test, the number of sample lots shall be set on the basis of the annual sales volume of an in-service family in the Union, as described in the following table:

Table B.1

Number of sample lots for ISC testing with Type 1 tests

EU Registrations per calendar year of vehicles in the sampling period	Number of sample lots(for Type 1 tests)
up to 100 000	1
100 001 to 200 000	2
above 200 000	3

Each sample lot shall include enough vehicle types, in order to ensure that at least 20 % of the total family sales are covered. When a family requires more than one sample lot to be tested, the vehicles in the second and third sample lots shall reflect different vehicle use conditions from those selected for the first sample.

5.9.Use of the Electronic Platform for in-service conformity and access to data required for testing

The Commission shall set up an electronic platform in order to facilitate the exchange of data between on the one side, the manufacturers, accredited labs or technical services and on the other side the granting type approval authority and the taking of the decision on the sample fail or pass.

The manufacturer shall complete the package on Testing Transparency referred to in Article 5 (12) in the format specified in Tables 1 and 2 of Appendix 5 and in the Table in this point and transmit it to the type-approval authority which grants the emission type-approval. Table 2 of Appendix 5 shall be used in order to allow the selection of vehicles from the same family for testing and along with the Table 1 provide sufficient information for vehicles to be tested.

Once the electronic platform referred to in the first paragraph becomes available, the type-approval authority which grants the emission type-approval shall upload the information in Tables 1 and 2 of Appendix 5 to this platform within 5 working days of receiving it.

All information in Tables 1 and 2 of Appendix 5 shall be accessible to the public in an electronic form free of charge.

The following information shall also be part of the package on Testing Transparency and shall be provided by the manufacturer free-of-charge within 5 working days of the request by an accredited laboratory or technical service.

5.10.Statistical Procedure

5.10.1.General

The verification of in-service conformity shall rely on a statistical method following the general principles of sequential sampling for inspection by attributes. The minimum sample size for a pass result is three vehicles, and the maximum cumulative sample size is ten vehicles for the Type 1 and RDE tests.

For the Type 4 and Type 6 tests a simplified method may be used, where the sample shall consist of three vehicles and shall be considered a fail if all three vehicles fail to pass the test, and a pass if all three vehicles pass the test. In cases where two out of three passed or failed, the type approval authority may decide to conduct further tests or proceed with accessing the compliance in accordance with point 6.1.

Test results shall not be multiplied by deterioration factors.

For vehicles that have a Declared Maximum RDE Values reported in point 48.2 of the Certificate of Conformity, as described in Annex IX of Directive 2007/46/EC which is lower than the emission limits set out in Annex I to Regulation (EC) No 715/2007, the conformity shall be checked both against the Declared Maximum RDE Value increased by the margin set out in point 2.1.1 of Annex IIIA and the not-to-exceed limit set out in in section 2.1. of that Annex. If the sample is found not to conform with the Declared Maximum RDE Values increased by the applicable measurement uncertainty margin, but pass with the not-to-exceed limit, the granting type approval authority shall require the manufacturer to take corrective actions.

Prior to the performance of the first ISC test, the manufacturer, accredited laboratory or technical service (“party”) shall notify the intent of performing in-service conformity testing of a given vehicle family to the granting type approval authority. Upon this notification, the granting type approval authority shall open a new statistical folder to process the results for each relevant combination of the following parameters for that particular party/or that pool of parties: vehicle family, emissions test type and pollutant. Separate statistical procedures shall be opened for each relevant combination of those parameters.

The granting type approval authority shall incorporate in each statistical folder only the results provided by the relevant party. The granting type approval authority shall keep a record of the number of tests performed, the number of failed and passed tests and other necessary data to support the statistical procedure.

Whereas more than one statistical procedure can be open at the same time for a given combination of test type and vehicle family, a party shall only be allowed to provide test results to one open statistical procedure for a given combination of test type and vehicle family. Each test shall be reported only once and all tests (valid, not valid, fail or pass, etc.) shall be reported.

Each ISC statistical procedure shall remain open until an outcome is reached when the statistical procedure arrives to a pass or fail decision for the sample in accordance point 5.10.5. However, if an outcome is not reached within 12 months of the opening of a statistical folder, the granting type approval authority shall close the statistical folder unless it decides to complete testing for that statistical folder within the following 6 months.

5.10.2.Pooling of ISC results

Test results from two or more accredited laboratories or technical services may be pooled for the purposes of a common statistical procedure. The pooling of test results shall require the written consent from all the interested parties providing test results to a pool of results, and a notification to the granting type approval authority prior to the start of testing. One of the parties pooling test results shall be designated as leader of the pool and be responsible for data reporting and communication with the granting type approval authority.

5.10.3.Pass/Fail/Invalid outcome for a single test

An ISC emissions test shall be considered as ‘passed’ for one or more pollutants when the emissions result is equal or below the emission limit set out in Annex I of Regulation (EC) No 715/2007 for that type of test.

An emissions test shall be considered as ‘failed’ for one or more pollutants when the emissions result is greater than the corresponding emission limit for that type of test. Each failed test result shall increase the ‘f’ count (see point 5.10.5) by 1 for that statistical instance.

An ISC emissions test shall be considered invalid if it does not respect the test requirements referred to in point 5.3. Invalid test results shall be excluded from the statistical procedure.

The results of all ISC tests shall be submitted to the granting type approval authority within ten working days from the execution of each test. The test results shall be accompanied by a comprehensive test report at the end of the tests. The results shall be incorporated in the sample in chronological order of execution.

The granting type approval authority shall incorporate all valid emission test results to the relevant open statistical procedure until a ‘sample fail’ or a ‘sample pass’ outcome is reached in accordance with point 5.10.5.

5.10.4.Treatment of Outliers

The presence of outlying results in the sample statistical procedure may lead to a ‘fail’ outcome in accordance with the procedures described below:

Outliers shall be categorised as intermediate or extreme.

An emissions test result shall be considered as an intermediate outlier if it is equal or greater than 1,3 times the applicable emission limit. The presence of two such outliers in a sample shall lead to a fail of the sample.

An emissions result shall be considered as an extreme outlier if it is equal or greater than 2,5 times the applicable emission limit. The presence of one such outlier in a sample shall lead to a fail of the sample. In such case, the plate number of the vehicle shall be communicated to the manufacturer and to the granting type approval authority. This possibility shall be communicated to the vehicle owners before testing.

5.10.5.Pass/Fail decision for a sample

For the purposes of deciding on a pass/fail result for the sample, ‘p’ is the count of passed results, and ‘f’ is the count of failed results. Each passed test result shall increase the ‘p’ count by 1 and each failed test result shall increase the ‘f’ count by 1 for the relevant open statistical procedure.

Upon the incorporation of valid emission test results to an open instance of the statistical procedure, the type approval authority shall perform the following actions:

update the cumulative sample size ‘n’ for that instance to reflect the total number of valid emissions tests incorporated to the statistical procedure;
following an evaluation of the results, update the count of passed results ‘p’ and the count of failed results ‘f’;
compute the number of extreme and intermediate outliers in the sample in accordance with point 5.10.4.
check whether a decision is reached with the procedure described below.

The decision depends on the cumulative sample size ‘n’, the passed and failed result counts ‘p’ and ‘f’, as well as the number of intermediate and/or extreme outliers in the sample. For the decision on a pass/fail of an ISC sample the granting type approval authority shall use the decision chart in Figure B.2 for vehicles based on types approved as of 1 January 2020 and the decision chart in Figure B.2.a for vehicles based on types approved until 31 December 2019. The charts indicate the decision to be taken for a given cumulative sample size ‘n’ and failed count result ‘f’.

Two decisions are possible for a statistical procedure for a given combination of vehicle family, emissions test type and pollutant:

‘Sample pass’ outcome shall be reached when the applicable decision chart from Figure B.2 or Figure B.2.a gives a “PASS” outcome for the current cumulative sample size ‘n’ and the count of failed results ‘f’.

‘Sample fail’ decision shall be reached when, for a given cumulative sample size ‘n’, when at least one of the following conditions is fulfilled:

the applicable decision chart from Figure B.2 or Figure B.2.a gives a “FAIL” decision for the current cumulative sample size ‘n’ and the count of failed results ‘f’.
there are two intermediate outliers;
there is one extreme outlier.

If no decision is reached, the statistical procedure shall remain open and further results shall be incorporated into it until a decision is reached or the procedure is closed in accordance with point 5.10.1.

5.10.6.ISC for completed vehicles and special purpose vehicles

The manufacturer of the base vehicle shall determine the allowed values for the parameters listed in Table B.3. The allowed Parameter Values for each family shall be recorded in the information document of the emissions type approval (see Appendix 3 to Annex I) and in the Transparency list 1 of Appendix 5 (rows 45 to 48). The second-stage manufacturer shall only be allowed to use the base vehicle emission values if the completed vehicle remains within the allowed Parameter Values. The parameter values for each completed vehicle shall be recorded in its Certificate of Conformity.

Table B.3

Allowed Parameter Values for multistage and special purpose vehicles to use the base vehicle emission type approval

Parameter Values:	Allowed values from - to:
Final Vehicle mass in running order (in kg)
Frontal area for final vehicle (in cm²)
Rolling resistance (kg/t)
Projected frontal area of air entrance of the front grille (in cm²)

If a completed or special purpose vehicle is tested and the result of the test is below the applicable emission limit, the vehicle shall be considered as a pass for the ISC family for the purposes of point 5.10.3.

If the result of the test on a completed or special purpose vehicle exceeds the applicable emission limits but is not higher than 1,3 times the applicable emission limits, the tester shall examine whether that vehicle complies with the values in table B.3. Any non-compliance with these values shall be reported to the granting type approval authority. If the vehicle does not comply with those values, the granting type approval authority shall investigate the reasons for the non-compliance and take the appropriate measures regarding the manufacturer of the completed or special purpose vehicle to restore conformity, including the withdrawal of the type-approval. If the vehicle complies with the values in table B.3, it shall be considered as a flagged vehicle for the in-service conformity family for the purposes of point 6.1.

If the result of the test exceeds 1,3 times the applicable emission limits, shall be considered as a fail for the in-service conformity family for the purposes of point 6.1., but not as an outlier for the relevant ISC family. If the completed or special purpose vehicle does not comply with the values in table B.3, this shall be reported to the granting type approval authority, who shall investigate the reasons for the non-compliance and take the appropriate measures regarding the manufacturer of the completed or special purpose vehicle to restore conformity, including the withdrawal of the type-approval.

6.Compliance Assessment

6.1.Within 10 days of the end of the ISC testing for the sample as referred to in point 5.10.5, the granting type approval authority shall start detailed investigations with the manufacturer in order to decide whether the ISC family (or part of it) complies with the ISC rules and whether it requires remedial measures. For multistage or special purpose vehicles the granting type approval authority shall also perform detailed investigations when there are at least three faulty vehicles with the same fault or five flagged vehicles in the same ISC family, as set out in point 5.10.6.

6.2.The granting type approval authority shall ensure that sufficient resources are available to cover the costs for compliance assessment. Without prejudice to national law, those costs shall be recovered by fees that can be levied on the manufacturer by the granting type approval authority.

The wide variety of exhaust pipe configurations, dimensions and exhaust mass flow rates may require compromises, guided by good engineering judgement, when selecting and installing the EFM(s). It is permissible to install an EFM with a diameter smaller than that of the exhaust outlet or the total projected frontal area of multiple outlets, providing it improves measurement accuracy and does not adversely affect the operation or the exhaust after-treatment as specified in point 3.4.2.

In multi-cylinder engines having distinct groups of manifolds, such as in a ‘V’ engine configuration, the sampling probe shall be positioned downstream of the point where the manifolds combine. If this is technically not feasible, multi-point sampling at locations of well-mixed exhaust may be used. In this case, the number and location of sampling probes shall match as far as possible those of the exhaust mass flow meters. In case of unequal exhaust flows, proportional sampling or sampling with multiple analysers shall be considered.’

3. Moving Averaging Windows

3.1. Definition of averaging windows

The instantaneous emissions calculated in accordance with Appendix 4 shall be integrated using a moving averaging window method, based on the reference CO₂ mass.

The principle of the calculation is as follows: The RDE distance-specific CO₂ 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 always the same fraction of the CO₂ mass emitted by the vehicle over the WLTP cycle. The moving window calculations are conducted with a time increment Δt corresponding to the data sampling frequency. These sub-sets used to calculate the vehicle on-road CO₂ emissions and its average speed are referred to as “averaging windows” in the following sections.

The calculation described in the present point shall be run from the first data point (forward).

The following data shall not be considered for the calculation of the CO₂ mass, the distance and the vehicle average speed in the averaging windows:

The periodic verification of the instruments and/or after the zero drift verifications;
Vehicle ground speed is smaller than 1 km/h.

The calculation shall start from when vehicle ground speed is higher than or equal to 1 km/h and include driving events during which no CO₂ is emitted and where the vehicle ground speed is higher than or equal to 1 km/h.

The mass emissions shall be determined by integrating the instantaneous emissions in g/s as specified in Appendix 4 to this Annex.

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

Figure 2 Definition of CO₂ mass based averaging windows

The duration (t ₂ _,j – t ₁ _,j ) of the j^th averaging window is determined by:

Where:

is the CO₂ mass measured between the test start and time t_i,j , [g];

is the half of the CO₂ mass emitted by the vehicle over the WLTP test conducted in accordance with Sub-Annex 6 to Annex XXI of this Regulation.

During type approval the CO₂ reference value shall be taken from the WLTP performed during type approval testing of the individual vehicle.

For ISC testing purposes, the reference CO₂ mass shall be obtained from point 12 of the Transparency list 1 of Appendix 5 of Annex II with interpolation between vehicle H and vehicle L (if relevant) as defined in Sub-Annex 7 of Annex XXI, using Test mass and Road load coefficients (f0, f1 & f2) obtained from the Certificate of Conformity for the individual vehicle as defined in Annex IX. The value for OVC-HEV vehicles is to be obtained from the WLTP test conducted using the Charge Sustaining mode.

t ₂ _,j shall be selected such as:

Where Δt is the data sampling period.

The CO₂ masses in the windows are calculated by integrating the instantaneous emissions calculated as specified in Appendix 4 to this Annex.

3.2. Calculation of window parameters

The following shall be calculated for each window determined in accordance with point 3.1.

The distance-specific CO₂ emissions ;
The average vehicle speed .

4. Evaluation of windows

4.1. Introduction

The reference dynamic conditions of the test vehicle are defined from the vehicle CO₂ emissions versus average speed measured at type approval on the Type 1 test and referred to as “vehicle CO₂ characteristic curve”. To obtain the distance specific CO₂ emissions, the vehicle shall be tested on the WLTP cycle in accordance with Annex XXI to this Regulation.

4.2. CO₂ Characteristic curve reference points

The distance-specific CO₂ emissions to be considered in this paragraph for the definition of the reference curve shall be obtained from point 12 of the Transparency list 1 of Appendix 5 of Annex II with interpolation between vehicle H and vehicle L (if relevant) as defined in Sub-Annex 7 of Annex XXI, using Test mass and Road load coefficients (f0, f1 & f2) obtained from the Certificate of Conformity for the individual vehicle as defined in Annex IX. The value for OVC-HEV vehicles is to be that obtained from the WLTP test conducted using the Charge Sustaining mode.

During type approval, the values shall be taken from the WLTP performed during type approval testing of the individual vehicle.

The reference points P ₁, P ₂ and P ₃ required to define the vehicle CO₂ characteristic curve shall be established as follows:

4.2.1. Point P ₁

= 18,882 km/h (Average Speed of the Low Speed phase of the WLTP cycle)

= Vehicle CO₂ emissions over the Low Speed phase of the WLTP cycle [g/km]

4.2.2. Point P ₂

= 56,664 km/h (Average Speed of the High Speed phase of the WLTP cycle)

= Vehicle CO₂ emissions over the High Speed phase of the WLTP cycle [g/km]

4.2.3. Point P ₃

= 91,997 km/h (Average Speed of the Extra High Speed phase of the WLTP cycle)

= Vehicle CO₂ emissions over the Extra High Speed phase of the WLTP cycle [g/km]

4.3. CO₂ Characteristic curve definition

Using the reference points defined in point 4.2, the characteristic curve CO₂ 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:

4.5. Verification of trip validity

4.5.1. Tolerances around the vehicle CO₂ characteristic curve

The upper tolerance of the vehicle CO₂ characteristic curve is tol _1H = 45 % for urban driving and tol _1H = 40 % for rural and motorway driving.

The lower tolerance of the vehicle CO₂ characteristic curve is tol _1L = 25 % for ICE and NOVC-HEV vehicles and tol _1L = 100 % for OVC-HEV vehicles.

4.5.2. Verification of test validity

The test is valid when it comprises at least 50 % of the urban, rural and motorway windows that are within the tolerances defined for the CO₂ characteristic curve.

For NOVC-HEVs and OVC-HEVs, if the minimum requirement of 50 % between tol_1H and tol_1L is not met, the upper positive tolerance tol_1H may be increased by steps of 1 % until the 50 % target is reached. When using this mechanism, the value of tol_1H shall never exceed 50 %.’

The trip validity shall be verified in accordance with point 9.2. of Annex IIIA. For the valid trips, the final RDE results are calculated as follows for vehicles with ICE, NOVC-HEV and OVC-HEV.

For the complete RDE trip and for the urban part of the RDE trip (k = t = total, k = u = urban):

M_RDE,k = m_RDE,k · RF_k

Upon the request of the manufacturer and only for type approvals granted before 1 January 2020,

RF_L ₁ = 1,20 and RF_L ₂ = 1,25;

in all other cases:

RF_L ₁ = 1,30 and RF_L ₂ = 1,50;

The RDE result evaluation factors RF_k (k = t = total, k = u = urban) shall be obtained using the functions laid down in point 2.2. for vehicles with ICE and NOVC-HEV, and in point 2.3. for OVC-HEV.

For the urban emissions, the relevant phases of the WLTP driving cycle shall be:

for ICE vehicles the first two WLTP phases, i.e. the Low and the Medium speed phases,

for NOVC-HEVs the whole WLTP driving cycle.

2.3. RDE result evaluation factor for OVC-HEV

The value of the RDE result evaluation factor depends on the ratio r_k between the distance-specific CO₂ emissions measured during the RDE test and the distance-specific CO₂ emitted by the vehicle over the WLTP test conducted using the Charge Sustaining mode in accordance with Sub-Annex 6 to Annex XXI of this Regulation, obtained from point 12 of the Transparency list 1 of Appendix 5 of Annex II with interpolation between vehicle H and vehicle L (if relevant) as defined in Sub-Annex 7 of Annex XXI, using Test mass and Road load coefficients (F0, F1 & F2) obtained from the Certificate of Conformity for the individual vehicle as defined in Annex IX. The ratio r_k is corrected by a ratio reflecting the respective usage of the internal combustion engine during the RDE trip and on the WLTP test, to be conducted using the charge sustaining mode. The formula below shall be subject to review by the Commission and shall be revised as a result of technical progress.

For either the urban or the total driving:

‘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 % for all speed values above 3 km/h and a sampling frequency of 1 Hz. This accuracy requirement is generally fulfilled by distance calibrated signals obtained from a wheel (rotational) speed sensor. Otherwise, acceleration shall be determined with an accuracy of 0,01 m/s² and a sampling frequency of 1 Hz. In this case the separate speed signal, in (v · a_pos ), shall have an accuracy of at least 0,1 km/h.

For N2 category vehicles that are equipped with a device limiting vehicle speed to 90 km/h, all datasets with v_i ≤ 60 km/h belong to the “urban” speed bin, all datasets with 60 km/h < v_i ≤ 80 km/h belong to the “rural” speed bin and all datasets with v_i > 80 km/h belong to the “motorway” speed bin.

The number of datasets with acceleration values a_i > 0,1 m/s² shall be greater or equal to 100 in each speed bin.

For each speed bin the average vehicle speed shall be calculated as follows:

, i = 1 to N_k, k= u, r, m

The positive cumulative elevation gain of a total trip shall be calculated by integrating all positive interpolated and smoothed road grades, i.e. road _grade,2(d). The result should be normalized by the total test distance dtot and expressed in metres of cumulative elevation gain per one hundred kilometres of distance.

The positive cumulative elevation gain of the urban part of a trip shall then be calculated based on the vehicle speed over each discrete way point:

v_w = 1 / (t_w,i – t_{w,i – 1}) · 60² / 1 000

Where:

v_w - waypoint vehicle speed [km/h]

All datasets with v_w =< 60 km/h belong to the urban part of the trip.

Integrate all of the positive interpolated and smoothed road grades that correspond to urban datasets.

Integrate the number of 1m waypoints which correspond to urban datasets and divide by 1 000 to calculate urban test distance d _urban [km].

5.1.2.For vehicles with a sealed fuel tank system, this shall also include having a system which, just before refuelling, releases the tank pressure exclusively through a vapour storage unit which has the sole function of storing fuel vapour. This ventilation route shall also be the only one used when the tank pressure exceeds its safe working pressure.

5.2.The test vehicle shall be selected in accordance with paragraph 5.5.2.

5.3.Vehicle testing condition

5.3.1.The types and amounts of lubricants and coolant for emissions testing shall be as specified for normal vehicle operation by the manufacturer.

5.3.2.The type of fuel for testing shall be as specified in Section A.1 of Annex IX.

5.3.3.All evaporative emissions controlling systems shall be in working order.

5.3.4.The use of any defeat device is prohibited in accordance with the provisions of Article 5(2) of Regulation (EC) No 715/2007.

Figure VI.3 Determination of the PF

5.2.1.The fuel tank system representative of a family shall be selected and mounted on a rig in a similar orientation as in the vehicle. The tank shall be filled to 40 ± 2 per cent of its nominal capacity with reference fuel at a temperature of 18 °C ± 2 °C. The rig with the fuel tank system shall be placed in a room with a controlled temperature of 40 °C ± 2 °C for 3 weeks.

5.2.2.At the end of the third week, the tank shall be drained and refilled with reference fuel at a temperature of 18 °C ± 2 °C to 40 ± 2 per cent of its nominal tank capacity.

Within 6 to 36 hours, the rig with the fuel tank system shall be placed in an enclosure. The last 6 hours of this period shall be at an ambient temperature of 20 °C ± 2 °C. In the enclosure, a diurnal procedure shall be performed over the first 24-hour period of the procedure described in paragraph 6.5.9. of this Appendix. The fuel vapour in the tank shall be vented to the outside of the enclosure to eliminate the possibility of the tank venting emissions being counted as permeation. The HC emissions shall be measured and the value shall be included in all relevant test reports as HC_3W.

5.2.3.The rig with the fuel tank system shall be placed again in a room with a controlled temperature of 40 °C ± 2 °C for the remaining 17 weeks.

5.2.4.At the end of the seventeenth week, the tank shall be drained and refilled with reference fuel at a temperature of 18 °C ± 2 °C to 40 ± 2 per cent of its nominal tank capacity.

Within 6 to 36 hours, the rig with the fuel tank system shall be placed in an enclosure. The last 6 hours of this period shall be at an ambient temperature of 20 °C ± 2 °C. In the enclosure, a diurnal procedure shall be performed over a first period of 24 hours of the procedure described in accordance with paragraph 6.5.9. of this Appendix. The fuel tank system shall be vented to the outside of the enclosure to eliminate the possibility of the tank venting emissions being counted as permeation. The HC emissions shall be measured and the value shall be included in all relevant test reports in this case as HC_20W.

5.2.5.The PF is the difference between HC_20W and HC_3W in g/24h calculated to 3 significant digits using the following equation:

PF = HC_20w – HC_3W

5.2.6.If the PF is determined by a supplier, the vehicle manufacturer shall inform the approval authority in advance of the determination to allow witness check in the supplier's facility.

5.2.7.The manufacturer shall provide the approval authority with a test report containing at least the following:

(a)

A full description of the fuel tank system tested, including information on the type of tank tested, whether the tank is metal, monolayer non-metal or multilayer, and which types of materials are used for the tank and other parts of the fuel tank system;

(b)

The weekly mean temperatures at which the ageing was performed;

(c)

The HC measured at week 3 (HC_3W);

(d)

The HC measured at week 20 (HC_20W);

(e)

The resulting permeability factor (PF).

5.2.8.As an alternative to paragraphs 5.2.1. to 5.2.7. of this Appendix, a manufacturer using multilayer tanks or metal tanks may choose to use an Assigned Permeability Factor (APF) instead of performing the complete measurement procedure mentioned above:

APF multilayer/metal tank = 120 mg /24 h

Where the manufacturer chooses to use an APF, the manufacturer shall provide the approval authority with a declaration in which the type of tank is clearly specified as well as a declaration of the type of materials used.

6. Test procedure for the measurement of hot soak and diurnal losses

6.1.Vehicle preparation

The vehicle shall be prepared in accordance to paragraphs 5.1.1. and 5.1.2. of Annex 7 of UN/ECE Regulation No 83. At the request of the manufacturer and with approval of the approval authority, non-fuel background emission sources (e.g. paint, adhesives, plastics, fuel/vapour lines, tyres, and other rubber or polymer components) may be reduced to typical vehicle background levels before testing (e.g. baking of tyres at temperatures of 50 °C or higher for appropriate periods, baking of the vehicle, draining washer fluid).

For a sealed fuel tank system, the vehicle canisters shall be installed so that access to canisters and connection/disconnection of canisters can be done easily.

6.2.Mode selections and gear shift prescriptions

6.2.1.For vehicles with manual shift transmissions, the gear shift prescriptions specified in Sub-Annex 2 of Annex XXI shall apply.

6.3.Test conditions

The tests included in this Annex shall be performed using the test conditions specific to interpolation family vehicle H with the highest cycle energy demand of all the interpolation families included in the evaporative emission family being considered.

Alternatively, at the request of the approval authority, any cycle energy representative of a vehicle in the family may be used for the test.

6.4.Flow of the test procedure

The test procedure for non-sealed and sealed tank systems shall be followed in accordance with the flow chart described in Figure VI.4.

The sealed fuel tank systems shall be tested with one of 2 options. One option is to test the vehicle with one continuous procedure. Another option, called the stand-alone procedure, is to test the vehicle with two separate procedures which will allow repeating the dynamometer test and the diurnal tests without repeating the tank depressurisation puff loss overflow test and the depressurisation puff loss measurement.

6.6.1.5.Canister loading and purge

The canister aged in accordance with the sequence described in paragraph 5.1. of this Appendix shall be loaded to 2 gram breakthrough in accordance with the procedure described in paragraph 5.1.6. of Annex 7 of UN/ECE Regulation No 83, and shall be subsequently purged with 25 ± 5 litres per minute with emission laboratory air. The volume of purge air shall not exceed the volume determined in paragraph 6.6.1.5.1. This loading and purging can be done either (a) using an on-board canister at a temperature of 20 °C or optionally 23 °C, or (b) by disconnecting the canister. In both cases, no further relief of the tank pressure is allowed.

6.6.1.5.1.Determination of maximum purge volume

The maximum purge amount Vol_max shall be determined by the following equation. In the case of OVC-HEVs, the vehicle shall be operated in charge-sustaining operating condition. This determination can also be done at a separate test or during the preconditioning drive.

3.IN-USE PERFORMANCE

3.1. General Requirements

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.

3.1.1.The requirements of paragraph 7.1.5. of Appendix 1 to Annex 11 to UN/ECE Regulation No 83 shall be understood as being as follows.

For new type approvals and new vehicles the monitor required by paragraph 3.3.4.7. of Annex 11 to UN/ECE Regulation No 83 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.

3.1.2.The requirements of paragraph 7.1.7. of Appendix 1 to Annex 11 to UN/ECE Regulation No 83 shall be understood as being as follows.

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 in accordance with paragraph 7.6. of Appendix 1 to Annex 11 to Regulation No 83 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 paragraph 7.1.9. of Appendix 1 to Annex 11 to Regulation No 83.

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.

3.1.3.Non-compliance with the requirements of paragraph 7.1.6. of Appendix 1 to Annex 11 to Regulation No 83 established by tests described in point 3.1.2 of this Appendix or paragraph 7.1.9 of Appendix 1 to Annex 11 to Regulation No 83 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 not explicitly refer to Article 13 of Regulation (EC) No 715/2007.

3.1.4.Paragraph 7.6.1. of Appendix 1 to Annex 11 of UN/ECE Regulation No 83 shall be replaced with the following:

‘7.6.1.The OBD system shall report, in accordance with the standard listed in paragraph 6.5.3.2.(a) of this Appendix, 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:

ANNEX VIIIU.K.

‘ANNEX XVIU.K. REQUIREMENTS FOR VEHICLES THAT USE A REAGENT FOR THE EXHAUST AFTER-TREATMENT SYSTEM

1.Introduction

This Annex sets out the requirements for vehicles that rely on the use of a reagent for the after-treatment system in order to reduce emissions. Every reference in this Annex to ‘reagent tank’ shall be understood as also applying to other containers in which a reagent is stored.

1.1.The capacity of the reagent tank shall be such that a full reagent tank does not need to be replenished over an average driving range of 5 full fuel tanks providing the reagent tank can be easily replenished (e.g. without the use of tools and without removing vehicle interior trim. The opening of an interior flap, in order to gain access for the purpose of reagent replenishment, shall not be understood as the removal of interior trim). If the reagent tank is not considered to be easy to replenish as described above, the minimum reagent tank capacity shall be at least equivalent to an average driving distance of 15 full fuel tanks. However, in the case of the option in paragraph 3.5., where the manufacturer chooses to start the warning system at a distance which may not be less than 2 400 km before the reagent tank becomes empty, the above restrictions on a minimum reagent tank capacity shall not apply.

1.2.In the context of this Annex, the term “average driving distance” shall be taken to be derived from the fuel or reagent consumption during a Type 1 test for the driving distance of a fuel tank and the driving distance of a reagent tank respectively.

2.Reagent indication

2.1.The vehicle shall include a specific indicator on the dashboard that informs the driver when reagent levels are below the threshold values specified in paragraph 3.5.

3.Driver warning system

3.1.The vehicle shall include a warning system consisting of visual alarms that informs the driver when an abnormality is detected in the reagent dosing, e.g. when emissions are too high, the reagent level is low, reagent dosing is interrupted, 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 cannot 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 paragraph 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 that they are 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 of the reagent tank becoming empty, or at the choice of the manufacturer at the latest when the level of reagent in the tank reaches one of the following levels:

(a)

a level expected to be sufficient for driving 150 % of an average driving range with a complete tank of fuel; or

(b)

10 % of the capacity of the reagent tank,

whichever occurs earlier.

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 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 paragraph 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 paragraph 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; and

(b)

The flow of reagent or injection of reagent as close as technically possible to the point of injection into an exhaust after-treatment 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 paragraph 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 paragraph 8. shall apply.

5.5.In the case of interruption in reagent dosing activity the driver warning system as referred to in paragraph 3. shall be activated, which shall display a message indicating an appropriate warning. Where the reagent dosing interruption is initiated by the engine system because the vehicle operating conditions are such that the vehicle's emission performance does not require reagent dosing, the activation of the driver warning system as referred to in paragraph 3. may be omitted, 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 paragraph 8. shall apply.

6.Monitoring NO_x emissions

6.1.As an alternative to the monitoring requirements referred to in paragraphs 4. and 5., manufacturers may use exhaust gas sensors directly to sense excess NO_x levels in the exhaust.

6.2.The manufacturer shall demonstrate that use of the sensors referred to in paragraph 6.1. above and any other sensors on the vehicle, results in the activation of the driver warning system as referred to in paragraph 3. above, 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 activation of the driver inducement system as referred to in paragraph 8.3., when the situations referred to in paragraphs 4.2., 5.4., or 5.5. occur.

For the purposes of this paragraph these situations are presumed to occur if the applicable NO_x OBD threshold limit of the tables set out in paragraph 2.3. 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 OBD threshold limits.

7.Storage of failure information

7.1.Where reference is made to this paragraph, 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 in accordance with the provisions of paragraph 2.3. of Appendix 1 to Annex XI. 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 cannot 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)

In the case that the warning system was activated at least 2 400 km before the reagent tank was expected to become empty, a level expected to be sufficient for driving the average driving range of the vehicle with a complete tank of fuel.

(b)

In the case that the warning system was activated at the level described in paragraph 3.5.(a), a level expected to be sufficient for driving 75 % of the average driving range of the vehicle with a complete tank of fuel; or

(c)

In the case that the warning system was activated at the level described in paragraph 3.5.(b), 5 % of the capacity of the reagent tank.

(d)

In the case that the warning system was activated ahead of the levels described in both paragraph 3.5.(a) and 3.5.(b) but less than 2 400 km in advance of the reagent tank becoming empty, whichever level described in (b) or (c) of this paragraph occurs earlier.

Where the alternative described in paragraph 6.1. is utilised, the system shall activate when the irregularities described in paragraphs 4. or 5. or the NO_x levels described in paragraph 6.2. have occurred.

The detection of an empty reagent tank and the irregularities mentioned in paragraphs 4., 5., or 6. shall result in the failure information storage requirements of paragraph 7. taking effect.

8.3.The manufacturer shall select which type of inducement system to install. The options for a system are described in paragraphs 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.

8.3.1.1.In the case that the warning system was activated at least 2 400 km before the reagent tank was expected to become empty, or the irregularities described in paragraphs 4. or 5. or the NO_x levels described in paragraph 6.2. have occurred, engine restarts shall be prevented immediately after the vehicle has travelled a distance expected to be sufficient for driving the average driving range of the vehicle with a complete tank of fuel since the activation of the inducement system.

8.3.1.2.In the case that the inducement system was activated at the level described in paragraph 8.2.(b), engine restarts shall be prevented immediately after the vehicle has travelled a distance expected to be sufficient for driving 75 % of the average driving range of the vehicle with a complete tank of fuel since the activation of the inducement system.

8.3.1.3.In the case that the inducement system was activated at the level described in paragraph 8.2.(c), engine restarts shall be prevented immediately after the vehicle has travelled a distance expected to be sufficient for driving the average driving range of the vehicle with 5 % of the capacity of the reagent tank, since the activation of the inducement system.

8.3.1.4.In addition, engine restarts shall be prevented immediately after the reagent tank becomes empty, should this situation occur earlier than the situations specified in paragraphs 8.3.1.1, 8.3.1.2., or 8.3.1.3.

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.

8.3.4.1.In the case that the warning system was activated at least 2 400 km before the reagent tank was expected to become empty, or the irregularities described in paragraphs 4. or 5. or the NO_x levels described in paragraph 6.2. have occurred, engine restarts shall be prevented immediately after the vehicle has travelled a distance expected to be sufficient for driving the average driving range of the vehicle with a complete tank of fuel since the activation of the inducement system.

8.3.4.2.In the case that the inducement system was activated at the level described in paragraph 8.2.(b), engine restarts shall be prevented immediately after the vehicle has travelled a distance expected to be sufficient for driving 75 % of the average driving range of the vehicle with a complete tank of fuel since the activation of the inducement system.

8.3.4.3.In the case that the inducement system was activated at the level described in paragraph 8.2.(c), engine restarts shall be prevented immediately after the vehicle has travelled a distance expected to be sufficient for driving the average driving range of the vehicle with 5 % of the capacity of the reagent tank, since the activation of the inducement system.

8.3.4.4.In addition, engine restarts shall be prevented immediately after the reagent tank becomes empty, should this situation occur earlier than the situations specified in paragraphs 8.3.4.1, 8.3.4.2. or 8.3.4.3.

8.4.Once the inducement system has prevented engine restarts, the inducement system shall only be deactivated if the irregularities specified in paragraphs 4., 5., or 6. have been rectified or if the quantity of reagent added to the vehicle meets at least one of the following criteria:

(a)

expected to be sufficient for driving 150 % of an average driving range with a complete tank of fuel; or

(b)

at least 10 % of the capacity of the reagent tank.

After a repair has been carried out to correct a fault where the OBD system has been triggered under paragraph 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 paragraph 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 Type 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 with clear 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 replenished by the vehicle driver between normal maintenance intervals. They shall indicate how the vehicle driver should replenish 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 replenishing 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 after-treatment system

Manufacturers shall ensure that the emission control system retains its emission control function during all ambient conditions, 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 is frozen, the manufacturer shall ensure that the reagent shall be liquefied and ready for use within 20 minutes of the vehicle being started at 258 K (– 15 °C) measured inside the reagent tank.’

1.General approach

1.1.The shifting procedures described in this Sub-Annex shall apply to vehicles equipped with manual shift transmissions.

1.2.The prescribed gears and shifting points are based on the balance between the power required to overcome driving resistance and acceleration, and the power provided by the engine in all possible gears at a specific cycle phase.

1.3.The calculation to determine the gears to use shall be based on engine speeds and full load power curves versus engine speed.

1.4.For vehicles equipped with a dual-range transmission (low and high), only the range designed for normal on-road operation shall be considered for gear use determination.

1.5.The prescriptions for the clutch operation shall not be applied if the clutch is operated automatically without the need of an engagement or disengagement of the driver.

1.6.This Sub-Annex shall not apply to vehicles tested in accordance with Sub-Annex 8.

2.Required data and precalculations

The following data are required and calculations shall be performed in order to determine the gears to be used when driving the cycle on a chassis dynamometer:

(a)

P_rated, the maximum rated engine power as declared by the manufacturer, kW;

(b)

n_rated, the rated engine speed declared by the manufacturer as the engine speed at which the engine develops its maximum power, min^{– 1};

(c)

n_idle, idling speed, min^{– 1}.

n_idle shall be measured over a period of at least 1 minute at a sampling rate of at least 1 Hz with the engine running in warm condition, the gear lever placed in neutral, and the clutch engaged. The conditions for temperature, peripheral and auxiliary devices, etc. shall be the same as described in Sub-Annex 6 for the Type 1 test.

The value to be used in this Sub-Annex shall be the arithmetic average over the measuring period, rounded or truncated to the nearest 10 min^{– 1};

(d)

ng, the number of forward gears.

The forward gears in the transmission range designed for normal on-road operation shall be numbered in descending order of the ratio between engine speed in min^{– 1} and vehicle speed in km/h. Gear 1 is the gear with the highest ratio, gear ng is the gear with the lowest ratio. ng determines the number of forward gears;

(e)

(n/v)_i, the ratio obtained by dividing the engine speed n by the vehicle speed v for each gear i, for i to ng_max, min^{– 1}/(km/h). (n/v)_i shall be calculated using the equations in paragraph 8. of Sub-Annex 7;

(f)

f₀, f₁, f₂, road load coefficients selected for testing, N, N/(km/h), and N/(km/h)² respectively;

(g)

n_max

n_max1 = n_{95_high}, the maximum engine speed where 95 per cent of rated power is reached, min^{– 1};

If n_{95_high} cannot be determined because the engine speed is limited to a lower value n_lim for all gears and the corresponding full load power is higher than 95 per cent of rated power, n_{95_high} shall be set to n_lim.

n_max2 = (n/v)(ng_max) × v_max,cycle

n_max3 = (n/v)(ng_max) × v_max,vehicle

where:

ng_vmax

is defined in paragraph 2.(i);

v_max,cycle

is the maximum speed of the vehicle speed trace in accordance with Sub-Annex 1, km/h;

v_max,vehicle

is the maximum speed of the vehicle in accordance with paragraph 2.(i), km/h;

(n/v)(ng_vmax)

is the ratio obtained by dividing engine speed n by the vehicle speed v for the gear ng_vmax, min^{– 1}/(km/h);

n_max

is the maximum of n_max1, n_max2 and n_max3, min^{– 1}.

(h)

P_wot(n), the full load power curve over the engine speed range

The power curve shall consist of a sufficient number of data sets (n, P_wot) so that the calculation of interim points between consecutive data sets can be performed by linear interpolation. Deviation of the linear interpolation from the full load power curve in accordance with Annex XX shall not exceed 2 per cent. The first data set shall be at n_{min_drive_set} (see point (k)(3)) or lower. The last data set shall be at n_max or higher engine speed. Data sets need not be spaced equally but all data sets shall be reported.

The data sets and the values P_rated and n_rated shall be taken from the power curve as declared by the manufacturer.

The full load power at engine speeds not covered by Annex XX shall be determined in accordance with the method described in Annex XX;

(i)

Determination of ng_vmax and v_max

ng_vmax, the gear in which the maximum vehicle speed is reached and shall be determined as follows:

If v_max(ng) ≥ v_max(ng – 1) and v_max(ng – 1) ≥ v_max(ng – 2), then:

ng_vmax = ng and v_max = v_max(ng).

If v_max(ng) < v_max(ng – 1) and v_max(ng – 1) ≥ v_max(ng – 2), then:

ng_vmax = ng – 1 and v_max = v_max(ng – 1),

otherwise, ng_vmax = ng -2 and v_max = v_max(ng – 2)

where:

v_max(ng)

is the vehicle speed at which the required road load power equals the available power P_wot in gear ng (see Figure A2/1a).

v_max(ng – 1)

is the vehicle speed at which the required road load power equals the available power P_wot in the next lower gear (gear ng – 1). See Figure A2/1b.

v_max(ng – 2)

is the vehicle speed at which the required road load power equals the available power P_wot in the gear ng – 2.

Vehicle speed values rounded to one place of decimal shall be used for the determination of v_max and ng_vmax.

The required road load power, kW, shall be calculated using the following equation:

where:

is the vehicle speed specified above, km/h.

The available power at vehicle speed v_max in gear ng, gear ng – 1 or gear ng – 2 may be determined from the full load power curve, P_wot(n), by using the following equations:

n_ng = (n/v)_ng × v_max(ng);

n_{ng – 1} = (n/v)_{ng – 1} × v_max(ng – 1);

n_{ng – 2} = (n/v)_{ng – 2} × v_max(ng – 2),

and by reducing the power values of the full load power curve by 10 per cent.

The method described above shall be extended to even lower gears, i.e. ng – 3, ng – 4, etc. if necessary.

If, for the purpose of limiting maximum vehicle speed, the maximum engine speed is limited to n_lim which is lower than the engine speed corresponding to the intersection of the road load power curve and the available power curve, then:

ng_vmax = ng_max and v_max = n_lim / (n/v)(ng_max).

Exclusion of a crawler gear

Gear 1 may be excluded at the request of the manufacturer if all of the following conditions are fulfilled:

(1)

The vehicle family is homologated to tow a trailer;

(2)

(n/v)₁ × (v_max / n_{95_high}) > 6,74;

(3)

(n/v)₂ × (v_max / n_{95_high}) > 3,85;

(4)

The vehicle, having a mass m_t as defined in the equation below, is able to pull away from standstill within 4 seconds, on an uphill gradient of at least 12 per cent, on five separate occasions within a period of 5 minutes.

m_t = m_r0 + 25 kg + (MC – m_r0 – 25 kg) × 0,28

(factor 0,28 in the above equation shall be used for category N vehicles with a gross vehicle mass up to 3,5 tonnes and shall be replaced by factor 0,15 in the case of category M vehicles),

where:

v_max

is the maximum vehicle speed as specified in paragraph 2. (i). Only the v_max value resulting from the intersection of the required road load power curve and the available power curve of the relevant gear shall be used for the conditions in (3) and (4) above. A v_max value resulting from a limitation of the engine speed which prevents this intersection of curves shall not be used;

(n/v)(ng_vmax)

is the ratio obtained by dividing the engine speed n by the vehicle speed v for gear ng_vmax, min^{– 1}/(km/h);

m_r0

is the mass in running order, kg;

is the gross train mass (gross vehicle mass + max. trailer mass), kg.

In this case, gear 1 shall not be used when driving the cycle on a chassis dynamometer and the gears shall be renumbered starting with the second gear as gear 1.

(k)

Definition of n_{min_drive}

n_{min_drive} is the minimum engine speed when the vehicle is in motion, min^{– 1};

(1)

For n_gear = 1, n_{min_drive} = n_idle,

(2)

For n_gear = 2,

(i)

for transitions from first to second gear:

n_{min_drive} = 1,15 × n_idle,

(ii)

for decelerations to standstill:

n_{min_drive} = n_idle.

(iii)

for all other driving conditions:

n_{min_drive} = 0,9 × n_idle.

(3)

For n_gear > 2, n_{min_drive} shall be determined by:

n_{min_drive} = n_idle + 0,125 ×( n_rated – n_idle ).

This value shall be referred to as n_{min_drive_set}.

The final results for n_{min_drive} shall be rounded to the nearest integer. Example:1 199,5 becomes 1 200, 1 199,4 becomes 1 199.

Values higher than n_{min_drive_set} may be used for n_gear > 2 if requested by the manufacturer. In this case, the manufacturer may specify one value for acceleration/constant speed phases (n_{min_drive_up}) and a different value for deceleration phases (n_{min_drive_down}).

Samples which have acceleration values ≥ – 0,1389 m/s² shall belong to the acceleration/constant speed phases.

In addition, for an initial period of time (t_{start_phase}), the manufacturer may specify higher values (n_{min_drive_start} and/or n_{min_drive_up_start}) for the values n_{min_drive} and/or n_{min_drive_up} for n_gear > 2 than specified above.

The initial time period shall be specified by the manufacturer but shall not exceed the low speed phase of the cycle and shall end in a stop phase so that there is no change of n_{min_drive} within a short trip.

All individually chosen n_{min_drive} values shall be equal to or higher than n_{min_drive_set} but shall not exceed (2 × n_{min_drive_set}).

All individually chosen n_{min_drive} values and t_{start_phase} shall be included in all relevant test reports.

Only n_{min_drive_set} shall be used as the lower limit for the full load power curve in accordance with paragraph 2(h).

3.Calculations of required power, engine speeds, available power, and possible gear to be used

3.1.Calculation of required power

For each second j of the cycle trace, the power required to overcome driving resistance and to accelerate shall be calculated using the following equation:

where:

P_required,j

is the required power at second j, kW;

a_j

is the vehicle acceleration at second j, m/s², and is calculated as follows:

;

is a factor taking the inertial resistances of the drivetrain during acceleration into account and is set to 1,03.

3.2.Determination of engine speeds

For any v_j < 1 km/h, it shall be assumed that the vehicle is standing still and the engine speed shall be set to n_idle. The gear lever shall be placed in neutral with the clutch engaged except 1 second before beginning an acceleration from standstill where first gear shall be selected with the clutch disengaged.

For each v_j ≥ 1 km/h of the cycle trace and each gear i, i = 1 to ng_max, the engine speed, n_i,j, shall be calculated using the following equation:

n_i,j = (n/v)_i × v_j

The calculation shall be performed with floating point numbers, the results shall not be rounded.

3.3.Selection of possible gears with respect to engine speed

The following gears may be selected for driving the speed trace at v_j:

(a)

All gears i < ng_vmax where n_{min_drive} ≤ n_i,j ≤ n_max1;

(b)

All gears i ≥ ng_vmax where n_{min_drive} ≤ n_i,j ≤ n_max2;

(c)

Gear 1, if n_1,j < n_{min_drive}.

If a_j < 0 and n_i,j ≤ n_idle, n_i,j shall be set to n_idle and the clutch shall be disengaged.

If a_j ≥ 0 and n_i,j < max(1,15 × n_idle; min. engine speed of the P_wot(n) curve), n_i,j shall be set to the maximum of 1,15 × n_idle or (n/v)_i × v_j and the clutch shall be set to “undefined”.

“undefined” covers any status of the clutch between disengaged and engaged, depending on the individual engine and transmission design. In this case the real engine speed may deviate from the calculated engine speed.

3.4.Calculation of available power

The available power for each possible gear i and each vehicle speed value of the cycle trace v_i shall be calculated using the following equation:

P_{available_i,j} = P_wot (n_i,j) × (1 – (SM + ASM))

where:

P_rated

is the rated power, kW;

P_wot

is the power available at n_i,j at full load condition from the full load power curve;

is a safety margin accounting for the difference between the stationary full load condition power curve and the power available during transition conditions. SM is set to 10 per cent;

ASM

is an additional power safety margin which may be applied at the request of the manufacturer.

When requested, the manufacturer shall provide the ASM values (in per cent reduction of the wot power) together with data sets for P_wot(n) as shown by the example in Table A2/1. Linear interpolation shall be used between consecutive data points. ASM is limited to 50 per cent.

The application of an ASM requires the approval of the approval authority.

Table A2/1

n	Pwot	SM per cent	ASM per cent	P_available
min^{– 1}	kW	SM per cent	ASM per cent	kW
700	6,3	10,0	20,0	4,4

6 400	164,3	10,0	0,0	147,8
6 600	156,4	10,0	0,0	140,8

3.5.Determination of possible gears to be used

The possible gears to be used shall be determined by the following conditions:

(a)

The conditions of paragraph 3.3. are fulfilled, and

(b)

For n_gear > 2, if P_{available_i,j} ≥ P_required,j.

The initial gear to be used for each second j of the cycle trace is the highest final possible gear, i_max. When starting from standstill, only the first gear shall be used.

The lowest final possible gear is i_min.

4.Additional requirements for corrections and/or modifications of gear use

The initial gear selection shall be checked and modified in order to avoid too frequent gearshifts and to ensure driveability and practicality.

An acceleration phase is a time period of more than 2 seconds with a vehicle speed ≥ 1 km/h and with monotonic increase of vehicle speed. A deceleration phase is a time period of more than 2 seconds with a vehicle speed ≥ 1 km/h and with monotonic decrease of vehicle speed.

Corrections and/or modifications shall be made in accordance with the following requirements:

(a)

If a one step higher gear (n + 1) is required for only 1 second and the gears before and after are the same (n) or one of them is one step lower (n – 1), gear (n + 1) shall be corrected to gear n.

Examples:

Gear sequence i – 1, i, i – 1 shall be replaced by:

i – 1, i – 1, i – 1;

Gear sequence i – 1, i, i – 2 shall be replaced by:

i – 1, i – 1, i – 2;

Gear sequence i – 2, i, i – 1 shall be replaced by:

i – 2, i – 1, i – 1.

Gears used during accelerations at vehicle speeds ≥ 1 km/h shall be used for a period of at least 2 seconds (e.g. a gear sequence 1, 2, 3, 3, 3, 3, 3 shall be replaced by 1, 1, 2, 2, 3, 3, 3). This requirement shall not be applied on downshifts during an acceleration phase. Such downshifts shall be corrected in accordance with paragraph 4(b). Gears shall not be skipped during acceleration phases.

However an upshift by two gears is permitted at the transition from an acceleration phase to a constant speed phase if the duration of the constant speed phase exceeds 5 seconds.

(b)

If a downshift is required during an acceleration phase the gear which is required during this downshift is noted (i_DS). The start point of a correction procedure is defined by either the last previous second when i_DS was identified, or the start point of the acceleration phase if all time samples before have gears > i_DS. The following check shall then be applied.

Working backwards from the end of the acceleration phase, the latest occurrence of a 10 second window containing i_DS for either 2 or more consecutive seconds, or 2 or more individual seconds shall be identified. The last usage of i_DS in this window defines the end point of the correction procedure. Between the start and end of the correction period, all requirements for gears greater than i_DS shall be corrected to a requirement of i_DS.

From the end of the correction period to the end of the acceleration phase, all downshifts with a duration of only one second shall be removed, if the downshift was a one step downshift. If the downshift was a two step downshift, all requirements for gears greater than or equal to i_DS up to the latest occurrence of i_DS shall be corrected to (i_DS + 1).

This final correction shall also be applied from the start point to the end of the acceleration phase, if no 10 second window containing i_DS for either 2 or more consecutive seconds or 2 or more individual seconds was identified.

Examples:

(i)

If the initially calculated gear use is:

2, 2, 3, [3, 4, 4, 4, 4, 3, 4, 4, 4, 4], 4, 4, 3, 4, 4, 4,

the gear use shall be corrected to:

2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4.

(ii)

If the initially calculated gear use is:

2, 2, 3, [3, 4, 4, 3, 4, 4, 4, 4, 4, 4], 4, 4, 4, 4, 3, 4,

the gear use shall be corrected to:

2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4.

(iii)

If the initially calculated gear use is:

2, 2, 3, [3, 4, 4, 4, 4, 4, 4, 4, 4, 4], 4, 4, 4, 3, 3, 4,

the gear use shall be corrected to:

2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4.

The first 10 second windows are indicated by square brackets in the examples above.

The underlined gears (e.g. 3) indicate those cases which could lead to a correction of the gear before it.

This correction shall not be performed for gear 1.

(c)

If gear i is used for a time sequence of 1 to 5 seconds and the gear prior to this sequence is one step lower and the gear after this sequence is one or two steps lower than within this sequence or the gear prior to this sequence is two steps lower and the gear after this sequence is one step lower than within the sequence, the gear for the sequence shall be corrected to the maximum of the gears before and after the sequence.

Examples:

(i)

Gear sequence i – 1, i, i – 1 shall be replaced by:

i – 1, i – 1, i – 1;

Gear sequence i – 1, i, i – 2 shall be replaced by:

i – 1, i – 1, i – 2;

Gear sequence i – 2, i, i – 1 shall be replaced by:

i – 2, i – 1, i – 1.

(ii)

Gear sequence i – 1, i, i, i – 1 shall be replaced by:

i – 1, i – 1, i – 1, i – 1;

Gear sequence i – 1, i, i, i – 2 shall be replaced by:

i – 1, i – 1, i – 1, i – 2;

Gear sequence i – 2, i, i, i – 1 shall be replaced by:

i – 2, i – 1, i – 1, i – 1.

(iii)

Gear sequence i – 1, i, i, i, i – 1 shall be replaced by:

i – 1, i – 1, i – 1, i – 1, i – 1;

Gear sequence i – 1, i, i, i, i – 2 shall be replaced by:

i – 1, i – 1, i – 1, i – 1, i – 2;

Gear sequence i – 2, i, i, i, i – 1 shall be replaced by:

i – 2, i – 1, i – 1, i – 1, i – 1.

(iv)

Gear sequence i – 1, i, i, i, i, i – 1 shall be replaced by:

i – 1, i – 1, i – 1, i – 1, i – 1, i – 1;

Gear sequence i – 1, i, i, i, i, i – 2 shall be replaced by:

i – 1, i – 1, i – 1, i – 1, i – 1, i – 2;

Gear sequence i – 2, i, i, i, i, i – 1 shall be replaced by:

i – 2, i – 1, i – 1, i – 1, i – 1, i – 1.

(v)

Gear sequence i – 1, i, i, i, i, i, i – 1 shall be replaced by:

i – 1, i – 1, i – 1, i – 1, i – 1, i – 1, i – 1.

Gear sequence i – 1, i, i, i, i, i, i – 2 shall be replaced by:

i – 1, i – 1, i – 1, i – 1, i – 1, i – 1, i – 2;

Gear sequence i – 2, i, i, i, i, i, i – 1 shall be replaced by:

i – 2, i – 1, i – 1, i – 1, i – 1, i – 1, i – 1.

In all cases (i) to (v), i – 1 ≥ i_min shall be fulfilled.

(d)

No upshift to a higher gear at the transition from an acceleration or constant speed phase to a deceleration phase shall be performed if the gear in the phase following the deceleration phase is lower than the upshifted gear.

Example:

If v_i ≤ v_{i + 1} and v_{i + 2} < v_{i + 1} and gear i = 4 and gear (i + 1 = 5) and gear (i + 2 = 5), then gear (i + 1) and gear (i + 2) shall be set to 4 if the gear for the phase following the deceleration phase is gear 4 or lower. For all following cycle trace points with gear 5 within the deceleration phase, the gear shall also be set to 4. If the gear following the deceleration phase is gear 5, an upshift shall be performed.

If there is an upshift during the transition and the initial deceleration phase by 2 gears, an upshift by 1 gear shall be performed.

No upshift to a higher gear shall be performed within a deceleration phase.

(e)

During a deceleration phase, gears with n_gear > 2 shall be used as long as the engine speed does not drop below n_{min_drive}.

Gear 2 shall be used during a deceleration phase within a short trip of the cycle (not at the end of a short trip) as long as the engine speed does not drop below (0,9 × n_idle).

If the engine speed drops below n_idle, the clutch shall be disengaged.

If the deceleration phase is the last part of a short trip shortly before a stop phase, the second gear shall be used as long as the engine speed does not drop below n_idle.

(f)

If during a deceleration phase the duration of a gear sequence between two gear sequences of 3 seconds or more is only 1 second, it shall be replaced by gear 0 and the clutch shall be disengaged.

If during a deceleration phase the duration of a gear sequence between two gear sequences of 3 seconds or more is 2 seconds, it shall be replaced by gear 0 for the 1st second and for the 2nd second with the gear that follows after the 2 second period. The clutch shall be disengaged for the 1st second.

Example: A gear sequence 5, 4, 4, 2 shall be replaced by 5, 0, 2, 2.

This requirement shall only be applied if the gear that follows after the 2 second period is > 0.

If several gear sequences with durations of 1 or 2 seconds follow one another, corrections shall be performed as follows:

A gear sequence i, i, i, i – 1, i – 1, i – 2 or i, i, i, i – 1, i – 2, i – 2 shall be changed to i, i, i, 0, i – 2, i – 2.

A gear sequence such as i, i, i, i – 1, i – 2, i – 3 or i, i, i, i – 2, i – 2, i – 3 or other possible combinations shall be changed to i, i, i, 0, i – 3, i – 3.

This change shall also be applied to gear sequences where the acceleration is ≥ 0 for the first 2 seconds and < 0 for the 3rd second or where the acceleration is ≥ 0 for the last 2 seconds.

For extreme transmission designs, it is possible that gear sequences with durations of 1 or 2 seconds following one another may last up to 7 seconds. In such cases, the correction above shall be complemented by the following correction requirements in a second step:

A gear sequence j, 0, i, i, i – 1, k with j > (i + 1) and k ≤ (i – 1) shall be changed to j, 0, i – 1, i – 1, i – 1, k, if gear (i – 1) is one or two steps below i_max for second 3 of this sequence (one after gear 0).

If gear (i – 1) is more than two steps below i_max for second 3 of this sequence, a gear sequence j, 0, i, i, i – 1, k with j > (i + 1) and k ≤ (i – 1) shall be changed to j, 0, 0, k, k, k.

A gear sequence j, 0, i, i, i-2, k with j > (i + 1) and k ≤ (i – 2) shall be changed to j, 0, i – 2, i – 2, i – 2, k, if gear (i – 2) is one or two steps below i_max for second 3 of this sequence (one after gear 0).

If gear (i – 2) is more than two steps below i_max for second 3 of this sequence, a gear sequence j, 0, i, i, i – 2, k with j > (i + 1) and k ≤ (i – 2) shall be changed to j, 0, 0, k, k, k.

In all cases specified above in this sub-paragraph, the clutch disengagement (gear 0) for 1 second is used in order to avoid too high engine speeds for this second. If this is not an issue and, if requested by the manufacturer, it is allowed to use the lower gear of the following second directly instead of gear 0 for downshifts of up to 3 steps. The use of this option shall be recorded.

If the deceleration phase is the last part of a short trip shortly before a stop phase and the last gear > 0 before the stop phase is used only for a period of up to 2 seconds, gear 0 shall be used instead and the gear lever shall be placed in neutral and the clutch shall be engaged.

Examples: A gear sequence of 4, 0, 2, 2, 0 for the last 5 seconds before a stop phase shall be replaced by 4, 0, 0, 0, 0. A gear sequence of 4, 3, 3, 0 for the last 4 seconds before a stop phase shall be replaced by 4, 0, 0, 0.

A downshift to first gear is not permitted during those deceleration phases.

5.Paragraphs 4.(a) to 4.(f) shall be applied sequentially, scanning the complete cycle trace in each case. Since modifications to paragraphs 4.(a) to 4.(f) may create new gear use sequences, these new gear sequences shall be checked three times and modified if necessary.

In order to enable the assessment of the correctness of the calculation, the average gear for v ≥ 1 km/h, rounded to four places of decimal, shall be calculated and included in all relevant test reports.’

The weight distribution of the vehicle shall be included in all relevant test reports and shall be used for any subsequent road load determination testing.’;

(d)

points 3. and 3.1. are replaced by the following:

‘3.General requirements

The manufacturer shall be responsible for the accuracy of the road load coefficients and shall ensure this for each production vehicle within the road load family. Tolerances within the road load determination, simulation and calculation methods shall not be used to underestimate the road load of production vehicles.

‘4.1.1.1.Permissible wind conditions

The maximum permissible wind conditions for road load determination are described in paragraphs 4.1.1.1.1. and 4.1.1.1.2.

In order to determine the applicability of the type of anemometry to be used, the arithmetic average of the wind speed shall be determined by continuous wind speed measurement, using a recognized meteorological instrument, at a location and height above the road level alongside the test road where the most representative wind conditions will be experienced.

If tests in opposite directions cannot be performed at the same part of the test track (e.g. on an oval test track with an obligatory driving direction), wind speed and direction at each part of the test track shall be measured. In this case the higher measured arithmetic average wind speed determines the type of anemometry to be used and the lower arithmetic average wind speed the criterion for the allowance of waiving of a wind correction.

4.1.1.1.1.Permissible wind conditions when using stationary anemometry

Stationary anemometry shall be used only when wind speeds over a period of 5 seconds average less than 5 m/s and peak wind speeds are less than 8 m/s for less than 2 seconds. In addition, the average vector component of the wind speed across the test road shall be less than 2 m/s during each valid run pair. Run pairs that do not meet the above criteria shall be excluded from the analysis. Any wind correction shall be calculated as given in paragraph 4.5.3. Wind correction may be waived when the lowest arithmetic average wind speed is 2 m/s or less.

4.1.1.1.2.Permissible wind conditions when using on-board anemometry

The arithmetic average of the wind speed during each valid run pair over the test road shall be less than 7 m/s with peak wind speeds of less than 10 m/s for more than 2 seconds. In addition, the average vector component of the wind speed across the road shall be less than 4 m/s during each valid run pair.

‘4.2.1.1.1.Without using the interpolation method

A test vehicle (vehicle H) with the combination of road load relevant characteristics (i.e. mass, aerodynamic drag and tyre rolling resistance) producing the highest cycle energy demand shall be selected from the family (see paragraphs 5.6. and 5.7. of this Annex).

If the aerodynamic influence of the different wheels within one interpolation family is not known, the selection shall be based on the highest expected aerodynamic drag. As a guideline, the highest aerodynamic drag may be expected for wheels with (a) the largest width, (b) the largest diameter, and (c) the most open structure design (in that order of importance).

The wheel selection shall be performed additional to the requirement of the highest cycle energy demand.

4.2.1.1.2.Using an interpolation method

At the request of the manufacturer, an interpolation method may be applied.

In this case, two test vehicles shall be selected from the family complying with the respective family requirement.

Test vehicle H shall be the vehicle producing the higher, and preferably highest, cycle energy demand of that selection, test vehicle L the one producing the lower, and preferably lowest, cycle energy demand of that selection.

All items of optional equipment and/or body shapes that are chosen not to be considered when applying the interpolation method shall be identical for both test vehicles H and L such that these items of optional equipment produce the highest combination of the cycle energy demand due to their road load relevant characteristics (i.e. mass, aerodynamic drag and tyre rolling resistance).

In the case where individual vehicles may be supplied with a complete set of standard wheels and tyres and a complete set of snow tyres (marked with 3 Peaked Mountain and Snowflake – 3PMS) with or without wheels, the additional wheels/tyres shall not be considered as optional equipment.

As a guidance, the following minimum deltas between vehicles H and L should be fulfilled for that road load relevant characteristic:

(i)

mass at least 30 kg;

(ii)

rolling resistance at least 1,0 kg/t;

(iii)

aerodynamic drag C_D × A at least 0,05 m².

To achieve a sufficient delta between vehicle H and L on a particular road load relevant characteristic, the manufacturer may artificially worsen vehicle H, e.g. by applying a higher test mass.’;

2.1.3.Background concentrations shall be measured for all compounds for which dilute mass emissions measurements are conducted. For exhaust emissions testing, this requires sampling and analysis of the dilution air.

2.1.3.1.Background particulate measurement

2.1.3.1.1.Where the manufacturer requests subtraction of either dilution air or dilution tunnel background particulate mass from emissions measurements, these background levels shall be determined in accordance with the procedures listed in paragraphs 2.1.3.1.1.1. to 2.1.3.1.1.3. of this Sub-Annex.

2.1.3.1.1.1.The maximum permissible background correction shall be a mass on the filter equivalent to 1 mg/km at the flow rate of the test.

2.1.3.1.1.2.If the background exceeds this level, the default figure of 1 mg/km shall be subtracted.

2.1.3.1.1.3.Where subtraction of the background contribution gives a negative result, the background level shall be considered to be zero.

2.1.3.1.2.Dilution air background particulate mass level shall be determined by passing filtered dilution air through the particulate background filter. This shall be drawn from a point immediately downstream of the dilution air filters. Background levels in μg/m³ shall be determined as a rolling arithmetic average of at least 14 measurements with at least one measurement per week.

2.1.3.1.3.Dilution tunnel background particulate mass level shall be determined by passing filtered dilution air through the particulate background filter. This shall be drawn from the same point as the particulate matter sample. Where secondary dilution is used for the test, the secondary dilution system shall be active for the purposes of background measurement. One measurement may be performed on the day of test, either prior to or after the test.

2.1.3.2.Background particle number determination

2.1.3.2.1.Where the manufacturer requests a background correction, these background levels shall be determined as follows:

2.1.3.2.1.1.

The background value may be either calculated or measured. The maximum permissible background correction shall be related to the maximum allowable leak rate of the particle number measurement system (0,5 particles per cm³) scaled from the particle concentration reduction factor, PCRF, and the CVS flow rate used in the actual test;

2.1.3.2.1.2.

Either the approval authority or the manufacturer may request that actual background measurements are used instead of calculated ones.

2.1.3.2.1.3.

Where subtraction of the background contribution gives a negative result, the PN result shall be considered to be zero.

2.1.3.2.2.The dilution air background particle number level shall be determined by sampling filtered dilution air. This shall be drawn from a point immediately downstream of the dilution air filters into the PN measurement system. Background levels in particles per cm³ shall be determined as a rolling arithmetic average of least 14 measurements with at least one measurement per week.

2.1.3.2.3.The dilution tunnel background particle number level shall be determined by sampling filtered dilution air. This shall be drawn from the same point as the PN sample. Where secondary dilution is used for the test the secondary dilution system shall be active for the purposes of background measurement. One measurement may be performed on the day of test, either prior to or after the test using the actual PCRF and the CVS flow rate utilised during the test.

The air temperature and humidity shall be measured at the test cell's cooling fan outlet at a minimum frequency of 0,1 Hz. For the temperature at the start of the test, see paragraph 2.8.1. of this Sub-Annex.

2.2.2.1.2.The specific humidity H of either the air in the test cell or the intake air of the engine shall be such that:

5,5 ≤ H ≤ 12,2 (g H₂O/kg dry air)

2.2.2.1.3.Humidity shall be measured continuously at a minimum frequency of 0,1 Hz.

2.2.2.2.Soak area

The soak area shall have a temperature set point of 23 °C and the tolerance of the actual value shall be within ± 3 °C on a 5-minute running arithmetic average and shall not show a systematic deviation from the set point. The temperature shall be measured continuously at a minimum frequency of 0,033 Hz (every 30 s).

2.3.Test vehicle

2.3.1.General

The test vehicle shall conform in all its components with the production series, or, if the vehicle is different from the production series, a full description shall be included in all relevant test reports. In selecting the test vehicle, the manufacturer and the approval authority shall agree which vehicle model is representative for the interpolation family.

For the measurement of emissions, the road load as determined with test vehicle H shall be applied. In the case of a road load matrix family, for the measurement of emissions, the road load as calculated for vehicle H_M in accordance with paragraph 5.1. of Sub-Annex 4 shall be applied.

If at the request of the manufacturer the interpolation method is used (see paragraph 3.2.3.2. of Sub-Annex 7), an additional measurement of emissions shall be performed with the road load as determined with test vehicle L. Tests on vehicles H and L should be performed with the same test vehicle and shall be tested with the shortest n/v ratio (with a tolerance of ± 1,5 per cent) within the interpolation family. In the case of a road load matrix family, an additional measurement of emissions shall be performed with the road load as calculated for vehicle L_M in accordance with paragraph 5.1. of Sub-Annex 4.

Road load coefficients and the test mass of test vehicle L and H may be taken from different road load families, as long as the difference between these road load families results from applying paragraph 6.8. of Sub-Annex 4, and the requirements in paragraph 2.3.2. of this Sub-Annex are maintained.

2.3.2.CO₂ interpolation range

2.3.2.1.The interpolation method shall only be used if:

(a)

The difference in CO₂ over the applicable cycle resulting from step 9 of Table A7/1 of Sub-Annex 7 between test vehicles L and H is between a minimum of 5 g/km and a maximum defined in paragraph 2.3.2.2.;

(b)

for all applicable phase values the CO₂ values resulting of step 9 of Table A7/1 of Sub-Annex 7 of vehicle H are higher than those of vehicle L.

If these requirements are not met, tests can be declared void and repeated in agreement with the approval authority.

2.3.2.2.The maximum delta CO₂ allowed over the applicable cycle resulting from step 9 of Table A7/1 of Sub-Annex 7 between test vehicles L and H is 20 per cent plus 5 g/km of the CO₂ emissions from vehicle H, but at least 15 g/km and not exceeding 30 g/km.

This restriction does not apply for the application of a road load matrix family.

2.3.2.3.At the request of the manufacturer and with approval of the approval authority, the interpolation line may be extrapolated to a maximum of 3 g/km above the CO₂ emission of vehicle H and/or below the CO₂ emission of vehicle L. This extension is valid only within the absolute boundaries of the interpolation range specified in paragraph 2.3.2.2.

For the application of a road load matrix family, extrapolation is not permitted.

When two or more interpolation families are identical regarding the requirements of paragraph 5.6. of this Annex, but are distinct because their overall range for CO₂ would be higher than the maximum delta specified in paragraph 2.3.2.2., then all individual vehicles of identical specification (e.g. make, model, optional equipment) shall belong to only one of the interpolation families.

2.3.3.Run-in

The vehicle shall be presented in good technical condition. It shall have been run-in and driven between 3 000 and 15 000 km before the test. The engine, transmission and vehicle shall be run-in in accordance with the manufacturer's recommendations.

2.4.Settings

2.4.2.2.The vehicle's dynamometer operation mode, if any, shall be activated by using the manufacturer's instruction (e.g. using vehicle steering wheel buttons in a special sequence, using the manufacturer's workshop tester, removing a fuse).

The manufacturer shall provide the approval authority a list of the deactivated devices and justification for the deactivation. The dynamometer operation mode shall be approved by the approval authority and the use of a dynamometer operation mode shall be included in all relevant test reports.

2.4.2.3.The vehicle's dynamometer operation mode shall not activate, modulate, delay or deactivate the operation of any part that affects the emissions and fuel consumption under the test conditions. Any device that affects the operation on a chassis dynamometer shall be set to ensure a proper operation.

2.4.2.4.Allocation of dynamometer type to test vehicle

2.4.2.4.1.If the test vehicle has two powered axles, and under WLTP conditions it is partially or permanently operated with two axles being powered or recuperating energy over the applicable cycle the vehicle shall be tested on a dynamometer in 4WD operation which fulfils the specifications in paragraphs 2.2. and 2.3. of Sub-Annex 5.

2.4.2.4.2.If the test vehicle is tested with only one powered axle, the test vehicle shall be tested on a dynamometer in 2WD operation which fulfils the specifications in paragraph 2.2. of Sub-Annex 5.

At the request of the manufacturer and with the approval of the approval authority a vehicle with one powered axle may be tested on a 4WD dynamometer in 4WD operation mode.

2.4.2.4.3.If the test vehicle is operated with two axles being powered in dedicated driver-selectable modes which are not intended for normal daily operation but only for special limited purposes, such as ‘mountain mode’ or ‘maintenance mode’, or when the mode with two powered axles is only activated in an off-road situation, the vehicle shall be tested on a dynamometer in 2WD operation which fulfils the specifications in paragraph 2.2. of Sub-Annex 5.

2.4.2.4.4.If the test vehicle is tested on a 4WD dynamometer in 2WD operation the wheels on the non-powered axle may rotate during the test, provided that the vehicle dynamometer operation mode and vehicle coastdown mode support this way of operation.

the conversion is only applied to the vehicle tested at the chassis dynamometer, the road load determination procedure shall be applied to the unconverted test vehicle.

2.4.2.5.2.This demonstration of equivalency shall apply to all vehicles in the same road load family. At the request of the manufacturer, and with approval of the approval authority, this demonstration of equivalency may be extended to other road load families upon evidence that a vehicle from the worst-case road load family was selected as the test vehicle.

2.4.2.6.Information on whether the vehicle was tested on a 2WD dynamometer or a 4WD dynamometer and whether it was tested on a dynamometer in 2WD operation or 4WD operation shall be included in all relevant test reports. In the case that the vehicle was tested on a 4WD dynamometer, with that dynamometer in 2WD operation, this information shall also indicate whether or not the wheels on the non-powered wheels were rotating.

2.4.3.The vehicle's exhaust system shall not exhibit any leak likely to reduce the quantity of gas collected.

2.4.4.The settings of the powertrain and vehicle controls shall be those prescribed by the manufacturer for series production.

2.4.5.Tyres shall be of a type specified as original equipment by the vehicle manufacturer.

The appropriate reference fuel as specified in Annex IX shall be used for testing.

2.4.7.Test vehicle preparation

2.4.7.1.The vehicle shall be approximately horizontal during the test so as to avoid any abnormal distribution of the fuel.

2.4.7.2.If necessary, the manufacturer shall provide additional fittings and adapters, as required to accommodate a fuel drain at the lowest point possible in the tank(s) as installed on the vehicle, and to provide for exhaust sample collection.

2.4.7.3.For PM sampling during a test when the regenerating device is in a stabilized loading condition (i.e. the vehicle is not undergoing a regeneration), it is recommended that the vehicle has completed > 1/3 of the mileage between scheduled regenerations or that the periodically regenerating device has undergone equivalent loading off the vehicle.

Between the tests on the first gaseous reference fuel and the second gaseous reference fuel, for vehicles with positive ignition engines fuelled with LPG or NG/biomethane or so equipped that they can be fuelled with either petrol or LPG or NG/biomethane, the vehicle shall be preconditioned again before the test on the second reference fuel.

2.6.2.Test cell

2.6.2.1.Temperature

During preconditioning, the test cell temperature shall be the same as defined for the Type 1 test (paragraph 2.2.2.1.1. of this Sub-Annex).

2.6.2.2.Background measurement

In a test facility in which there may be possible contamination of a low particulate emitting vehicle test with residue from a previous test on a high particulate emitting vehicle, it is recommended, for the purpose of sampling equipment preconditioning, that a 120 km/h steady state drive cycle of 20 minutes duration be driven by a low particulate emitting vehicle. Longer and/or higher speed running is permissible for sampling equipment preconditioning if required. Dilution tunnel background measurements, if applicable, shall be taken after the tunnel preconditioning, and prior to any subsequent vehicle testing.

2.6.4.1.1.If the initiation of the powertrain start procedure is not successful, e.g. the engine does not start as anticipated or the vehicle displays a start error, the test is void, preconditioning tests shall be repeated and a new test shall be driven.

2.6.4.1.2.In the cases where LPG or NG/biomethane is used as a fuel, it is permissible that the engine is started on petrol and switched automatically to LPG or NG/biomethane after a predetermined period of time that cannot be changed by the driver. This period of time shall not exceed 60 seconds.

It is also permissible to use petrol only or simultaneously with gas when operating in gas mode provided that the energy consumption of gas is higher than 80 per cent of the total amount of energy consumed during the Type 1 test. This percentage shall be calculated in accordance with the method set out in Appendix 3 to this Sub-Annex.

2.6.4.2.The cycle starts on initiation of the powertrain start procedure.

2.6.4.3.For preconditioning, the applicable WLTC shall be driven.

2.10.1.2.Filter preparation

2.10.1.2.1.At least 1 hour before the test, the filter shall be placed in a petri dish protecting against dust contamination and allowing air exchange, and placed in a weighing chamber (or room) for stabilization.

At the end of the stabilization period, the filter shall be weighed and its weight shall be included in all relevant test sheets. The filter shall subsequently be stored in a closed petri dish or sealed filter holder until needed for testing. The filter shall be used within 8 hours of its removal from the weighing chamber (or room).

The filter shall be returned to the stabilization room within 1 hour after the test and shall be conditioned for at least 1 hour before weighing.

If, at the 80-hour point, two reference filters are employed and one filter fails the ± 5 μg criterion, the sample filter weighing may be considered valid under the condition that the sum of the absolute differences between specific and rolling means from the two reference filters shall be less than or equal to 10 μg.

2.14.3.6.In the case that less than half of the reference filters meet the ± 5 μg criterion, the sample filter shall be discarded, and the emissions test repeated.

In all other cases, reference filters shall be replaced at least every 30 days and in such a manner that no sample filter is weighed without comparison to a reference filter that has been present in the weighing chamber (or room) for at least one day.

2.14.3.7.If the weighing chamber (or room) stability criteria outlined in paragraph 4.2.2.1. of Sub-Annex 5 are not met, but the reference filter weighings meet the above criteria, the vehicle manufacturer has the option of accepting the sample filter weights or voiding the tests, repairing the weighing chamber (or room) control system and re-running the test.

Sub-Annex 6 - Appendix 1U.K. Emissions test procedure for all vehicles equipped with periodically regenerating systems

1.General

1.1.This Appendix defines the specific provisions regarding testing a vehicle equipped with periodically regenerating systems as defined in paragraph 3.8.1. of this Annex.

1.2.During cycles where regeneration occurs, emission standards need not apply. If a periodic regeneration occurs at least once per Type 1 test and has already occurred at least once during vehicle preparation or the distance between two successive periodic regenerations is more than 4 000 km of driving repeated Type 1 tests, it does not require a special test procedure. In this case, this Appendix does not apply and a K_i factor of 1,0 shall be used.

1.3.The provisions of this Appendix shall apply for the purposes of PM measurements only and not PN measurements.

1.4.At the request of the manufacturer, and with approval of the approval authority, the test procedure specific to periodically regenerating systems need not apply to a regenerative device if the manufacturer provides data demonstrating that, during cycles where regeneration occurs, emissions remain below the emissions limits for the relevant vehicle category. In this case, a fixed K_i value of 1,05 shall be used for CO₂ and fuel consumption.

1.5.At the request of the manufacturer and with the agreement of the approval authority the Extra High phase may be excluded for determining the regenerative factor K_i for Class 2 and Class 3 vehicles.

2.Test procedure

The test vehicle shall be capable of inhibiting or permitting the regeneration process provided that this operation has no effect on original engine calibrations. Prevention of regeneration is only permitted during loading of the regeneration system and during the preconditioning cycles. It is not permitted during the measurement of emissions during the regeneration phase. The emission test shall be carried out with the unchanged, original equipment manufacturer's (OEM) control unit. At the request of the manufacturer and with agreement of the approval authority, an “engineering control unit” which has no effect on original engine calibrations may be used during K_i determination.

2.1.Exhaust emissions measurement between two WLTCs with regeneration events

2.1.1.The arithmetic average emissions between regeneration events and during loading of the regenerative device shall be determined from the arithmetic mean of several approximately equidistant (if more than two) Type 1 tests. As an alternative, the manufacturer may provide data to show that the emissions remain constant (± 15 per cent) on WLTCs between regeneration events. In this case, the emissions measured during the Type 1 test may be used. In any other case, emissions measurements for at least two Type 1 cycles shall be completed: one immediately after regeneration (before new loading) and one as close as possible prior to a regeneration phase. All emissions measurements shall be carried out in accordance with this Sub-Annex and all calculations shall be carried out in accordance with paragraph 3. of this Appendix.

2.1.2.The loading process and K_i determination shall be made during the Type 1 driving cycle on a chassis dynamometer or on an engine test bench using an equivalent test cycle. These cycles may be run continuously (i.e. without the need to switch the engine off between cycles). After any number of completed cycles, the vehicle may be removed from the chassis dynamometer and the test continued at a later time. Upon request of the manufacturer and with approval of the approval authority, a manufacturer may develop an alternative procedure and demonstrate its equivalency, including filter temperature, loading quantity and distance driven. This may be done on an engine bench or on a chassis dynamometer.

2.1.3.The number of cycles D between two WLTCs where regeneration events occur, the number of cycles over which emission measurements are made n and mass emissions measurement M′_sij for each compound i over each cycle j shall be included in all relevant test sheets.

2.2.Measurement of emissions during regeneration events

2.2.1.Preparation of the vehicle, if required, for the emissions test during a regeneration phase, may be completed using the preconditioning cycles in paragraph 2.6. of this Sub-Annex or equivalent engine test bench cycles, depending on the loading procedure chosen in paragraph 2.1.2. of this Appendix.

2.2.2.The test and vehicle conditions for the Type 1 test described in this Annex apply before the first valid emission test is carried out.

2.2.3.Regeneration shall not occur during the preparation of the vehicle. This may be ensured by one of the following methods:

2.2.3.1.

A “dummy” regenerating system or partial system may be fitted for the preconditioning cycles.

2.2.3.2.

Any other method agreed between the manufacturer and the approval authority.

2.2.4.A cold start exhaust emissions test including a regeneration process shall be performed in accordance with the applicable WLTC.

2.2.5.If the regeneration process requires more than one WLTC, each WLTC shall be completed. Use of a single particulate sample filter for multiple cycles required to complete regeneration is permissible.

If more than one WLTC is required, subsequent WLTC(s) shall be driven immediately, without switching the engine off, until complete regeneration has been achieved. In the case that the number of gaseous emission bags required for the multiple cycles would exceed the number of bags available, the time necessary to set up a new test shall be as short as possible. The engine shall not be switched off during this period.

2.2.6.The emission values during regeneration M_ri for each compound i shall be calculated in accordance with paragraph 3. of this Appendix. The number of applicable test cycles d measured for complete regeneration shall be included in all relevant test sheets.

4.Alternatives in the measurement process

4.1.Worst case approach vehicle cool down

On request by the manufacturer and with approval by the approval authority, the Type 1 Test procedure for cool down may be applied instead of provisions of paragraph 3.6 of this Sub-Annex 6a. For that purpose:

(a)

The provisions of paragraph 2.7.2. of Sub-Annex 6 shall apply with the additional requirement of a minimum soak time of 9 hours.

(b)

The engine temperature shall be within ± 2 °C of the set point T_reg before the start of the ATCT test. That temperature shall be included in all relevant test sheets. In this case, the provision for cool down described in paragraph 3.9. of this Sub-Annex 6a and the criteria on engine compartment insulation can be skipped for all vehicles in the family.

This alternative is not allowed if the vehicle is equipped with an active heat storage device.

The application of that approach shall be included in all relevant test reports.

4.2.ATCT family composed of a single Interpolation family

In the case, that the ATCT family consists of only one interpolation family, the provision for cool down described in paragraph 3.9. of this Sub-Annex 6a can be skipped. This shall be included in all relevant test reports.

4.3.Alternative engine temperature measurement

In the case that measuring the coolant temperature is not feasible, on request of the manufacturer and with approval of the approval authority, instead of using the coolant temperature for the provision for cool down described in paragraph 3.9. of this Sub-Annex 6a, the engine oil temperature may be used. In that case, for all vehicles within the family the engine oil temperature shall be used.

The application of that procedure shall be included in all relevant test reports.’

2.9

‘Charge depleting operation’ means, for OVC-HEVs, the state of vehicle operation when the current REESS SOC is higher than the charge sustaining target SOC value and, while it may fluctuate, the intent of the vehicle control system is to deplete the SOC from a higher level down to the charge sustaining target SOC value.

2.10

‘Driver-selectable charge increasing operation’ means, for OVC-HEVs, the operating condition in which the driver has selected a mode of operation, with the intention to increase the REESS SOC.

3. Information to be determined, stored and made available

4.1With regard to the information specified in point 3, the manufacturer shall ensure that the OBFCM device provides the most accurate values that can be achieved by the measurement and calculation system of the engine control unit.

4.2Notwithstanding point 4.1, the manufacturer shall ensure that the accuracy is higher than – 0,05 and lower than 0,05 calculated with three decimals using the following formula:

Where:

Fuel_Consumed_WLTP (litres)

is the fuel consumption determined at the first test carried out in accordance with point 1.2 of Sub-Annex 6 of Annex XXI, calculated in accordance with paragraph 6 of Sub-Annex 7 of that Annex, using emission results over the total cycle before applying corrections (output of step 2 in table A7/1 of Sub-Annex 7), multiplied by the actual distance driven and divided by 100.

Fuel_Consumed_OBFCM (litres)

is the fuel consumption determined for the same test using the differentials of the parameter “Total fuel consumed (lifetime)” as provided by the OBFCM device.

For OVC-HEVs the charge-sustaining Type 1 test shall be used.

4.2.1If the accuracy requirements set out in point 4.2 are not met, the accuracy shall be recalculated for subsequent Type 1 tests performed in accordance with point 1.2 of Sub-Annex 6, in accordance with the formulae in point 4.2, using the fuel consumed determined and accumulated over all performed tests. The accuracy requirement shall be deemed to be fulfilled once the accuracy is higher than – 0,05 and lower than 0,05.

4.2.2If the accuracy requirements set out in point 4.2.1 are not met following the subsequent tests pursuant to this point, additional tests may be performed for the purpose of determining the accuracy, however, the total number of tests shall not exceed three tests for a vehicle tested without using the interpolation method (vehicle H), and six tests for a vehicle tested using the interpolation method (three tests for vehicle H and three tests for vehicle L). The accuracy shall be recalculated for the additional subsequent Type 1 tests in accordance with the formulae in point 4.2, using the fuel consumed determined and accumulated over all performed tests. The requirement shall be deemed to be fulfilled once the accuracy is higher than – 0,05 and lower than 0,05. Where the tests have been performed only for the purpose of determining the accuracy of the OBFCM device, the results of the additional tests shall not be taken into account for any other purposes.

5. Access to the information provided by the OBFCM device

5.1The OBFCM device shall provide for standardised and unrestricted access of the information specified in point 3, and shall conform to the standards referred to in points 6.5.3.1 (a) and 6.5.3.2 (a) of Paragraph 6.5.3. of Appendix 1 to Annex 11 to UN/ECE Regulation No 83, understood as set out in Point 2.8. of Appendix 1 to Annex XI to this Regulation.

5.2.By way of exemption from the reset conditions specified in the standards referred to in point 5.1 and notwithstanding points 5.3. and 5.4., once the vehicle has entered into service the values of the lifetime counters shall be preserved.

5.3The values of the lifetime counters may be reset only for those vehicles for which the memory type of the engine control unit is unable to preserve data when not powered by electricity. For those vehicles the values may be reset simultaneously only in the case the battery is disconnected from the vehicle. The obligation to preserve the values of the lifetime counters shall in this case apply for new type approvals at the latest from 1 January 2022 and for new vehicles from 1 January 2023.

5.4.In the case of malfunctioning affecting the values of the lifetime counters, or replacement of the engine control unit, the counters may be reset simultaneously to ensure that the values remain fully synchronised.’
