This is a legislation item that originated from the EU

After exit day there will be three versions of this legislation to consult for different purposes. The legislation.gov.uk version is the version that applies in the UK. The EU Version currently on EUR-lex is the version that currently applies in the EU i.e you may need this if you operate a business in the EU.

The web archive version is the official version of this legislation item as it stood on exit day before being published to legislation.gov.uk and any subsequent UK changes and effects applied. The web archive also captured associated case law and other language formats from EUR-Lex.

Status:

EU Directives are being published on this site to aid cross referencing from UK legislation. After exit day no further amendments will be applied to this version.

ANNEX IU.K.Amendments to Directive 2005/55/EC

1.Annex I is amended as follows:U.K.

(a)

Section 1 is replaced by the following:

1.This Directive applies to the control of gaseous and particulate pollutants, useful life of emission control devices, conformity of in-service vehicles/engines and onboard diagnostic (OBD) systems of all motor vehicles, and to engines as specified in Article 1 with the exception of those vehicles of category M1, N1, N2 and M2 for which type approval has been granted under Regulation (EC) No 715/2007 of the European Parliament and of the Council(1).

From 3 January 2009 up to the dates specified in Article 10(2) of Regulation (EC) No 715/2007 for new approvals and in Article 10(3) of that Regulation for extensions, type approvals may continue to be granted under this Directive for vehicles of category N1, N2 and M2 with a reference mass below 2 610 kg.

(b)

In section 2.1, the following definitions are added:

 “reference mass” means the mass of the vehicle in running order less the uniform mass of the driver of 75 kg and increased by a uniform mass of 100 kg.

“mass of the vehicle in running order” means the mass described in Section 2.6 of Annex I to Directive 2007/46/EC.

(c)

The following point 4.5 is added:

4.5.At the request of the manufacturer, the type approval of a completed vehicle given under this Directive shall be extended to its incomplete vehicle with a reference mass below 2 610 kg. Type approvals shall be extended if the manufacturer can demonstrate that all bodywork combinations expected to be built onto the incomplete vehicle, increase the reference mass of the vehicle to above 2 610 kg.

(d)

In point 6.2, the following subparagraphs are inserted after the fourth subparagraph:

For petrol engines, the test procedures set out in Annex VII of Directive 2005/78/EC shall apply.

For diesel engines, the test procedure for smoke opacity in Annex VI of Directive 2005/78/EC shall apply.

2.Annex II is amended as follows:U.K.

3.Appendix 1 of Annex III is amended as follows:U.K.

(a)

In Section 2, point 2.7.4 is replaced by the following:

2.7.4.Particulate sampling

A single filter shall be used for the complete test procedure. The modal weighting factors specified in the test cycle procedure shall be taken into account by taking a sample proportional to the exhaust mass flow during each individual mode of the cycle. This can be achieved by adjusting sample flow rate, sampling time, and/or dilution ratio, accordingly, so that the criterion for the effective weighting factors in Section 6.6 is met.

The sampling time per mode shall be at least four seconds per 0,01 weighting factor. Sampling shall be conducted as late as possible within each mode. Particulate sampling shall be completed no earlier than five seconds before the end of each mode.

(b)

In Section 6, the following points 6.5 and 6.6 are added:

6.5.Calculation of the specific emission

The particulate emission shall be calculated in the following way:

6.6.Effective weighting factor

The effective weighting factor Wfei for each mode shall be calculated in the following way:

The value of the effective weighting factors shall be within ± 0,003 (0,005 for the idle mode) of the weighting factors listed in Section 2.7.1 of this appendix.
