Regulation 2

SCHEDULE 1AE+W+SESSENTIAL REQUIREMENTS (Annex I to the Directive)

A regulated measuring instrument shall provide a high level of metrological protection in order that any party affected can have confidence in the result of measurement, and shall be designed and manufactured to a high level of quality in respect of the measurement technology and security of the measurement data.

The essential requirements that shall be met by regulated measuring instruments are set out below and are supplemented, where appropriate, by instrument-specific requirements in Schedules 1C to 1J that provide more detail on certain aspects of the general requirements.

The solutions adopted in the pursuit of the essential requirements shall take account of the intended use of the instrument and any foreseeable misuse thereof.

DEFINITIONS

MeasurandThe measurand is the particular quantity subject to measurement
Influence quantityAn influence quantity is a quantity that is not the measurand but that affects the result of measurement.
Rated Operating ConditionsThe rated operating conditions are the values for the measurand and influence quantities making up the normal working conditions of an instrument.
DisturbanceAn influence quantity having a value within the limits specified in the appropriate requirement but outside the specified rated operating conditions of the regulated measuring instrument. An influence quantity is a disturbance if for that influence quantity the rated operating conditions are not specified.
Critical change valueThe critical change value is the value at which the change in the measurement result is considered undesirable.
Material MeasureA material measure is a device intended to reproduce or supply in a permanent manner during its use one or more known values of a given quantity.
Direct sales

A trading transaction is direct sales if:

— the measurement result serves as the basis for the price to pay; and

— at least one of the parties involved in the transaction related to measurement is a consumer or any other party requiring a similar level of protection; and

— all the parties in the transaction accept the measurement result at that time and place.

Climatic environmentsClimatic environments are the conditions in which regulated measuring instruments may be used. To cope with climatic differences, a range of temperature limits has been defined.
UtilityA utility is regarded as a supplier of electricity, gas or water.

ESSENTIAL REQUIREMENTS

Allowable Errors

1.1.  Under rated operating conditions and in the absence of a disturbance, the error of measurement shall not exceed the maximum permissible error (MPE) value as laid down in the appropriate instrument-specific requirements.

Unless stated otherwise in the instrument-specific Schedules, MPE is expressed as a bilateral value of the deviation from the true measurement value.

1.2.  Under rated operating conditions and in the presence of a disturbance, the performance requirement shall be as laid down in the appropriate instrument-specific requirements.

Where the instrument is intended to be used in a specified permanent continuous electromagnetic field the permitted performance during the radiated electromagnetic field-amplitude modulated test shall be within MPE.

1.3.  The manufacturer shall specify the climatic, mechanical and electromagnetic environments in which the instrument is intended to be used, power supply and other influence quantities likely to affect its accuracy, taking account of the requirements laid down in the appropriate instrument-specific Schedules.

1.3.1  Climatic environments

The manufacturer shall specify the upper temperature limit and the lower temperature limit from any of the values in Table 1 unless otherwise specified in Schedules 1C to 1J and indicate whether the instrument is designed for condensing or non-condensing humidity as well as the intended location for the instrument, i.e. open or closed.

Temperature Limits
Upper temperature limit30 oC40 oC55 oC70 oC
Lower temperature limit5 oC-10 oC-25 oC-40 oC

1.3.2  (a) Mechanical environments are classified into classes M1 to M3 as described below.

M1This class applies to instruments used in locations with vibration and shocks of low significance, e.g. for instruments fastened to light supporting structures subject to negligible vibrations and shocks transmitted from local blasting or pile-driving activities, slamming doors, etc.
M2This class applies to instruments used in locations with significant or high levels of vibration and shock, e.g. transmitted from machines and passing vehicles in the vicinity or adjacent to heavy machines, conveyor belts, etc.
M3This class applies to instruments used in locations where the level of vibration and shock is high and very high, e.g. for instruments mounted directly on machines, conveyor belts, etc.

(b)The following influence quantities shall be considered in relation with mechanical environments:

  • — vibration

  • — mechanical shock

1.3.3.  (a) Electromagnetic environments are classified into classes E1, E2 or E3 as described below, unless otherwise laid down in the appropriate instrument-specific Schedules.

E1This class applies to instruments used in locations with electromagnetic disturbances corresponding to those likely to be found in residential, commercial and light industrial buildings.
E2This class applies to instruments used in locations with electromagnetic disturbances corresponding to those likely to be found in other industrial buildings.
E3

This class applies to instruments supplied by the battery of a vehicle. Such instruments shall comply with the requirements of E2 and the following additional requirements:

— voltage reductions caused by energising the starter-motor circuits of internal combustion engines,

— load dump transients occurring in the event of a discharged battery being disconnected while the engine is running.

(b)The following influence quantities shall be considered in relation with electromagnetic environments:

  • — voltage interruptions;

  • — short voltage reductions;

  • — voltage transients on supply lines and/or signal lines;

1.3.4.  Other influence quantities to be considered, where appropriate, are:

  • — voltage variation;

  • — mains frequency variation;

  • — power frequency magnetic fields;

  • — any other quantity likely to influence in a significant way the accuracy of the instrument.

1.4.  When carrying out the tests as envisaged in these Regulations, the following points shall apply:

1.4.1  Basic rules for testing and the determination of errors

Essential requirements specified in paragraphs 1.1 and 1.2 shall be verified for each relevant influence quantity. Unless otherwise specified in the appropriate instrument-specific Schedule, these essential requirements apply when each influence quantity is applied and its effect evaluated separately, all other influence quantities being kept relatively constant at their reference value.

Metrological tests shall be carried out during or after the application of the influence quantity, whichever condition corresponds to the normal operational status of the instrument when that influence quantity is likely to occur.

1.4.2  Ambient humidity

(a)According to the climatic operating environment in which the instrument is intended to be used either the damp heat-steady state (non-condensing) or damp heat cyclic (condensing) test may be appropriate.

(b)The damp heat cyclic test is appropriate where condensation is important or when penetration of vapour will be accelerated by the effect of breathing. In conditions where non-condensing humidity is a factor the damp-heat steady state is appropriate.

Reproducibility

2.  The application of the same measurand in a different location or by a different user, all other conditions being the same, shall result in the close agreement of successive measurements. The difference between the measurement results shall be small when compared with the MPE.

Repeatability

3.  The application of the same measurand under the same conditions of measurement shall result in the close agreement of successive measurements. The difference between the measurement results shall be small when compared with the MPE.

4.  Permissible effect of disturbances

4.1.  General

As electrical energy meters are directly connected to the mains supply and as mains current is also one of the measurands, a special electromagnetic environment is used for electricity meters.

The meter shall comply with the electromagnetic environment E2 and the additional requirements in paragraphs 4.2 and 4.3.

The electromagnetic environment and permissible effects reflect the situation that there are disturbances of long duration which shall not affect the accuracy beyond the critical change values and transient disturbances, which may cause a temporary degradation or loss of function or performance but from which the meter shall recover and shall not affect the accuracy beyond the critical change values.

When there is a foreseeable high risk due to lightning or where overhead supply networks are predominant, the metrological characteristics of the meter shall be protected.

In the case of electromechanical electricity meters, no critical change values are defined for harmonic contents in the current circuits and for DC and harmonics in the current circuit.

Permissible effect of transient electromagnetic phenomena

4.3.1  The effect of an electromagnetic disturbance on an electrical energy meter shall be such that during and immediately after a disturbance:

— any output intended for testing the accuracy of the meter does not produce pulses or signals corresponding to an energy of more than the critical change value,

and in reasonable time after the disturbance the meter shall:

  • — recover to operate within the MPE limits, and

  • — have all measurement functions safeguarded, and

  • — allow recovery of all measurement data present prior to the disturbance, and

  • — not indicate a change in the registered energy of more than the critical change value.

(m being the number of measuring elements of the meter, Un in Volts and Imax in Amps).

4.3.2.  For overcurrent the critical change value is 1.5 %.

Suitability

5.1.  Below the rated operating voltage the positive error of the meter shall not exceed 10 %.

5.2.  The display of the total energy shall have a sufficient number of digits to ensure that when the meter is operated for 4,000 hours at full load (I = Imax, U = Un and PF = 1) the indication does not return to its initial value and shall not be able to be reset during use.

5.3.  In the event of loss of electricity in the circuit, the amounts of electrical energy measured shall remain available for reading during a period of at least 4 months.

Running with no load

5.4.  When the voltage is applied with no current flowing in the current circuit (current circuit shall be open circuit), the meter shall not register energy at any voltage between 0.8 ∙ Un and 1.1 Un.

Starting

5.5.  The meter shall start and continue to register at Un, PF = 1 (polyphase meter with balanced loads) and a current which is equal to Ist.

Units

6.  The electrical energy measured shall be displayed in kilowatt-hours or in megawatt-hours.

Putting into use

SCHEDULE 1HE+W+STAXIMETERS (MI-007) (Annex IX to the Directive)

The relevant requirements of Schedule 1A, the specific requirements of this Schedule and the conformity assessment procedures listed in this Schedule apply to taximeters.

DEFINITIONS

Appropriate Licensing Authority

Within this Schedule, “appropriate licensing authority” means –

(a)in relation to the area to which the Metropolitan Public Carriage Act 1869 M2 applies, Transport for London;

(b)in relation to any other area in England and Wales, the authority responsible for licensing taxis in that area;

(d)and in relation to Northern Ireland, the Department of the Environment for Northern Ireland.

Taximeter

A device that works together with a signal generator M3 to make a regulated measuring instrument.

This device measures duration, calculates distance on the basis of a signal delivered by the distance signal generator. Additionally, it calculates and displays the fare to be paid for a trip on the basis of the calculated distance and/or the measured duration of the trip.

Fare

The total amount of money due for a trip based on a fixed initial hire fee and/or the length and/or the duration of the trip. The fare does not include a supplement charged for extra services.

Cross-over speed

The speed value found by division of a time tariff value by a distance tariff value.

Normal calculation mode S (single application of tariff)

Fare calculation based on application of the time tariff below the cross-over speed and application of the distance tariff above the cross-over speed.

Normal calculation mode D (double application of tariff)

Fare calculation based on simultaneous application of time tariff and distance tariff over the whole trip.

Operating position

The different modes in which a taximeter fulfils the different parts of its functioning. The operating positions are distinguished by the following indications:

‘For Hire’:The operating position in which the fare calculation is disabled
‘Hired’:The operating position in which the fare calculation takes place on the basis of a possible initial charge and a tariff for distance travelled and/or time of the trip
‘Stopped’:The operating position in which the fare due for the trip is indicated and at least the fare calculation based on time is disabled.

DESIGN REQUIREMENTS

1.  The taximeter shall be designed to calculate the distance and to measure the duration of a trip.

2.  The taximeter shall be designed to calculate and display the fare, incrementing in steps equal to the resolution fixed by the appropriate licensing authority in the operation position ‘Hired’. The taximeter shall also be designed to display the final value for the trip in the operating position ‘Stopped’.

3.  A taximeter shall be able to apply the normal calculation modes S and D. It shall be possible to choose between these calculation modes by a secured setting.

4.  A taximeter shall be able to supply the following data through an appropriate secured interface(s):

PERMISSIBLE EFFECT OF DISTURBANCES

8.  Electromagnetic immunity

8.1.  The electromagnetic class that applies is E3.

8.2.  The MPE laid down in paragraph 7 shall also be respected in the presence of an electromagnetic disturbance. POWER SUPPLY FAILURE

9.  In case of a reduction of the voltage supply to a value below the lower operating limit as specified by the manufacturer, the taximeter shall:

  • — continue to work correctly or resume its correct functioning without loss of data available before the voltage drop if the voltage drop is temporary, i.e. due to restarting the engine;

  • — abort an existing measurement and return to the position ‘For Hire’ if the voltage drop is for a longer period.

OTHER REQUIREMENTS

10.  The conditions for the compatibility between the taximeter and the distance signal generator shall be specified by the manufacturer of the taximeter.

11.  If there is a supplement charge for an extra service, entered by the driver on manual command, this shall be excluded from the fare displayed. However, in that case a taximeter may display temporarily the value of the fare including the supplementary charge.

12.  If the fare is calculated according to calculation mode D a taximeter may have an additional display mode in which only the total distance and duration of the trip are displayed in real time.

13.  All values displayed for the passenger shall be suitably identified. These values as well as their identification shall be clearly readable under daylight and night conditions.

The relevant requirements of Schedule 1A, the specific requirements of this Schedule and the conformity assessment procedures listed in this Schedule, apply to exhaust gas analysers to the extent that they are also regulated measuring instruments.

The volume fractions of the exhaust gas components are expressed as a percentage (% vol) for carbon monoxide (CO), carbon dioxide (CO2) and oxygen (O2) and in parts per million (ppm vol) for hydrocarbons (HC).

The content of HC has to be expressed as concentration of n-hexane (C6H14), measured with near-infrared absorption techniques.

DEFINITIONS

LambdaLambda is a dimensionless value representative of the burning efficiency of an engine in terms of air/fuel ratio in the exhaust gases.

SPECIFIC REQUIREMENTS

Instrument Classes

1.  Two classes (0 and I) are being defined for exhaust gas analysers. The relevant minimum measuring ranges for these classes are shown in Table 1.

Impact Assessments

Impact Assessments generally accompany all UK Government interventions of a regulatory nature that affect the private sector, civil society organisations and public services. They apply regardless of whether the regulation originates from a domestic or international source and can accompany primary (Acts etc) and secondary legislation (SIs). An Impact Assessment allows those with an interest in the policy area to understand:

  • Why the government is proposing to intervene;
  • The main options the government is considering, and which one is preferred;
  • How and to what extent new policies may impact on them; and,
  • The estimated costs and benefits of proposed measures.
