For this purpose, the values displayed by the instrument are used for calculation.

Permissible effect of disturbances

4. For each of the volume fractions measured by the instrument, the critical change value is equal to the MPE for the parameter concerned.

5. The effect of an electromagnetic disturbance shall be such that

— either the change in the measurement result is not greater than the critical change value laid down in paragraph 4;

— or the presentation of the measurement result is such that it cannot be taken for a valid result.

The lambda value shall be displayed with a resolution of 0.001.

7. The standard deviation of 20 measurements shall not be greater than one third of the modulus of the MPE for each applicable gas volume fraction.

8. For measuring CO, CO

, the instrument under similar conditions must indicate a value differing less than 0.1% vol from zero within 60 seconds after changing from fresh air to an oxygen-free gas.

9. The components in the exhaust gas, other than the components whose values are subject to the measurement, shall not affect the measurement results by more than the half of the modulus of the MPEs when those components are present in the following maximum volume fractions

10. An exhaust gas analyser shall have an adjustment facility that provides operations for zero-setting, gas calibration and internal adjustment. The adjustment facility for zero-setting and internal adjustment shall be automatic.

11. For automatic or semi-automatic adjustment facilities, the exhaust gas analyser shall be unable to make a measurement as long as the adjustments have not been made.

12. An exhaust gas analyser shall detect hydrocarbon residues in the gas handling system. It shall not be possible to carry out a measurement if the hydrocarbon residues, present before any measurement, exceed 20 ppm vol.

13. An exhaust gas analyser shall have a device for automatically recognising any malfunctioning of the sensor of the oxygen channel due to wear or a break in the connecting line.

14. If the exhaust gas analyser is capable to operate with different fuels (e.g. petrol or liquefied gas), there shall be the possibility to select the suitable coefficients for the Lambda calculation without ambiguity concerning the appropriate formula.

EXPLANATORY NOTE

(This note is not part of the Instrument and does not purport to be a legal interpretation).

These Regulations come into effect on the signing thereof and implement Directive 2004/22/EC of the European Parliament and of the Council of 31 March 2004 on the harmonisation of the laws of Member States relating to Measuring Instruments.

They provide for the free movement within the Community of certain instruments and set out essential requirements, which must be met for instruments intended for certain specified uses. These Regulations implement the provisions of the Directive relating to the following categories of instrument

• Water Meters For Cold Water

• Gas Meters And Volume Conversion Devices

• Active Electrical Energy Meters

• Measuring Systems For The Continuous And Dynamic Measurement Of Quantities Of Liquids Other Than Water

• Automatic Weighing Instruments

• Taximeters

• Material Measures Of Length

• Capacity Serving Measures

• Dimensional Measuring Instruments

• Exhaust Gas Analysers

They provide that the essential requirements of the Directive may be met through adoption by a manufacturer of the appropriate normative document, subject to the procedure stipulated in Article 16(1) of the Directive, containing technical specifications. They also provide for the appointment of notified bodies to carry out the various functions such as type-approval, verification and quality system approval and set out the obligations on manufacturers and the conditions under which they may issue a declaration of conformity and attach the CE mark and the Supplementary Metrology Mark to instruments.

The Regulations contain provisions for the withdrawal from the market or imposition of restrictions on the placing on the market of instruments bearing the CE mark and the Supplementary Metrology Mark that do not meet the requirements of the Regulations.

Regulations that applied to the classes of instruments within the scope of these Regulations are repealed. The Regulations also provide for an appeals procedure, market surveillance, powers of inspectors & authorised officers and penalties for offences.

1 Directive 80/181/EEC as amended.

1 OJ L 316, 31.10.1992, p. 12. Directive repealed by Directive 2003/96/EC (OJ L 283, 31.10.2003, p. 51).

1 OJ L 42, 15.2.1975, p. 1. Directive as last amended by Directive 89/676/EEC (OJ L 398, 30.12.1989, p. 18).

2 OJ L 46, 21.2.1976, p. 1. Directive as last amended by the EEA Agreement.

1 The distance signal generator is outside the scope of these Regulations.

1 OJ L 350, 28.12.1998, p. 17.

15. 3. Adequate measures shall be taken to prevent the display of totalised values from being used to deceive passengers.

16. Automatic change of tariffs is allowed due to the

— distance of the trip;

— duration of the trip;

— time of the day;

— date;

— day of the week.

17. If properties of the taxi are important for the correctness of the taximeter, the taximeter shall provide means to secure the connection of the taximeter to the taxi in which it is installed.

18. For the purpose of testing after installation, the taximeter shall be equipped with the possibility to test separately the accuracy of time and distance measurement and the accuracy of the calculation.

19. A taximeter and its installation instructions specified by the manufacturer shall be such that, if installed according to the manufacturer’s instructions, fraudulent alterations of the measurement signal representing the distance travelled are sufficiently excluded.

20. The general essential requirement dealing with fraudulent use shall be fulfilled in such a way that the interests of the customer, the driver, the driver’s employer and the fiscal authorities are protected.

21. A taximeter shall be designed so that it can respect the MPEs without adjustment during a period of one year of normal use.

22. The taximeter shall be equipped with a real-time clock by means of which the time of the day and the date are kept, one or both can be used for automatic change of tariffs. The requirements for the real-time clock are

— The timekeeping shall have an accuracy of 0.02%;

— The correction possibility of the clock shall be not more than 2 minutes per week. Correction for summer and wintertime shall be performed automatically;

— Correction, automatic or manually, during a trip shall be prevented.

23. The values of distance travelled and time elapsed, when displayed or printed in accordance with this Directive, shall use the following units

Distance travelled

— in the United Kingdom and Ireland: until the date which will be fixed by these Member States according to Article (1)(

b

) of Directive 80/181/EEC: kilometres or miles;

— in all other Member States: kilometres.

Time elapsed

— seconds, minutes or hours, as may be suitable; keeping in mind the necessary resolution and the need to prevent misunderstandings.

SCHEDULE MI-008A

MATERIAL MEASURES of LENGTH

The relevant essential requirements of Schedule III, the specific requirements of this Schedule and the conformity assessment procedures listed in this Schedule, apply to material measures of length defined below. However, the requirement for the supply of a copy of declarations of conformity may be interpreted as applying to a batch or consignment rather than each individual instrument.

DEFINITIONS

Material measure of length

An instrument comprising scale marks whose distances are given in legal units of length.
