Council Directive of 20 March 1970 on the approximation of the laws of the Member States on measures to be taken against air pollution by emissions from motor vehicles (70/220/EEC) (repealed)

[F1 2. TEST EQUIPMENT U.K.

2.1. Summary U.K.

[F2 2.1.1. This chapter deals with the equipment needed for low ambient temperature exhaust emission tests on vehicles equipped with positive-ignition engines, as defined in section 5.3.5. of Annex I.] Equipment required and specifications are equivalent to the requirements for the Type I test as specified in Annex III, with appendices, if specific requirements for the Type VI test are not prescribed. Sections 2.2 to 2.6 describe deviations applicable to Type VI low ambient temperature testing. U.K.

Textual Amendments

F2 Substituted by Directive 2001/100/EC of the European Parliament and of the Council of 7 December 2001 amending Council Directive 70/220/EEC on the approximation of the laws of the Member States on measures to be taken against air pollution by emissions from motor vehicles (Text with EEA relevance).

2.2. Chassis dynamometer U.K.

2.2.1. The requirements of section 4.1 of Annex III apply. The dynamometer must be adjusted to simulate the operation of a vehicle on the road at 266 °K (-7 ° C). Such adjustment may be based on a determination of the road load force profile at 266 °K (-7 ° C). Alternatively the driving resistance determined according to Appendix 3 of Annex III may be adjusted for a 10 % decrease of the coast-down time. The technical service may approve the use of other methods of determining the driving resistance. U.K.

2.2.2. For calibration of the dynamometer the provisions of Appendix 2 of Annex III apply. U.K.

2.3. Sampling system U.K.

2.3.1. The provisions of section 4.2 of Annex III and Appendix 5 of Annex III apply. Section 2.3.2 in Appendix 5 is modified to read: ‘The piping configuration, flow capacity of the CVS, and the temperature and specific humidity of the dilution air (which may be different from the vehicle combustion air source) must be controlled so as to virtually eliminate water condensation in the system (a flow of 0,142 to 0,165 m ² /s is sufficient for most vehicles).’ U.K.

2.4. Analytical equipment U.K.

2.4.1. The provisions of section 4.3 of Annex III apply, but only for carbon monoxide, carbon dioxide, and hydrocarbon testing. U.K.

2.4.2. For calibrations of the analytical equipment the provisions of Appendix 6 of Annex III apply. U.K.

2.5. Gases U.K.

2.5.1. The provisions of section 4.5 of Annex III apply, where they are relevant. U.K.

2.6. Additional equipment U.K.

2.6.1. For equipment used for the measurement of volume, temperature, pressure and humidity the provisions in sections 4.4 and 4.6 of Annex III apply.] U.K.
