7. CONFORMITY OF PRODUCTION U.K.

7.1. General requirements U.K.

Measures to ensure conformity of production shall be taken in accordance with Article 12 of Directive 2007/46/EC. Conformity of production shall be checked on the basis of the description in the type-approval certificates set out in Appendix 4 to this Annex. In applying Appendices 1, 2 or 3, the measured emission of the gaseous and particulate pollutants from engines subject to checking for conformity of production shall be adjusted by application of the appropriate deterioration factors (DF’s) for that engine as recorded in the Addendum to the EC type-approval certificate granted in accordance with this Regulation.

The provisions of Annex X to Directive 2007/46/EC shall be applicable where the approval authorities are not satisfied with the auditing procedure of the manufacturer.

All engines subject to tests shall be randomly taken from the series production.

7.2. Emissions of pollutants U.K.

7.2.1. If emissions of pollutants are to be measured and an engine type-approval has had one or more extensions, the tests shall be carried out on the engines described in the information package relating to the relevant extension. U.K.

7.2.2. Conformity of the engine subjected to a pollutant test: U.K.

After submission of the engine to the authorities, the manufacturer may not carry out any adjustment to the engines selected.

7.2.2.1. Three engines shall be taken from the series production of the engines under consideration. Engines shall be subjected to testing on the WHTC, and on the WHSC if applicable, for the checking of the production conformity. The limit values shall be those set out in Annex I to Regulation (EC) No 595/2009. U.K.

7.2.2.2. Where the approval authority is satisfied with the production standard deviation given by the manufacturer in accordance with Annex X to Directive 2007/46/EC, the tests shall be carried out according to Appendix 1 to this Annex. U.K.

Where the approval authority is not satisfied with the production standard deviation given by the manufacturer in accordance with Annex X to Directive 2007/46/EC, the tests shall be carried out according to Appendix 2 to this Annex.

At the manufacturer’s request, the tests may be carried out in accordance with Appendix 3 to this Annex.

7.2.2.3. On the basis of tests of the engine by sampling as set out in point 7.2.2.2, the series production of the engines under consideration is regarded as conforming where a pass decision is reached for all the pollutants and as non-conforming where a fail decision is reached for one pollutant, in accordance with the test criteria applied in the appropriate Appendix. U.K.

When a pass decision has been reached for one pollutant, this decision may not be changed as a consequence of a result from any additional tests made in order to reach a decision for the other pollutants.

If a pass decision is not reached for all the pollutants and if no fail decision is reached for any pollutant, a test is carried out on another engine (see Figure 1).

If no decision is reached, the manufacturer may at any time decide to stop testing. In that case a fail decision is recorded.

7.2.3. The tests shall be carried out on newly manufactured engines. U.K.

7.2.3.1. At the request of the manufacturer, the tests may be carried out on engines which have been run-in up to a maximum of 125 hours. In this case, the running-in procedure shall be conducted by the manufacturer who shall undertake not to make any adjustments to those engines. U.K.

7.2.3.2. When the manufacturer requests to conduct a running-in procedure in accordance with point 7.2.3.1, it may be carried out on either of the following: U.K.

(a)

all the engines that are tested;

(b)

the first engine tested, with the determination of an evolution coefficient as follows:

(i)

the pollutant emissions shall be measured both on the newly manufactured engine and before the maximum of 125 hours set in point 7.2.3.1 on the first engine tested;

(ii)

the evolution coefficient of the emissions between the two tests shall be calculated for each pollutant:

• Emissions on second test/Emissions first test

• The evolution coefficient may have a value less than one.

The subsequent test engines shall not be subjected to the running-in procedure, but their emissions when newly manufactured shall be modified by the evolution coefficient.

In this case, the values to be taken shall be the following:

(a)

for the first engine, the values from the second test;

(b)

for the other engines, the values when newly manufactured multiplied by the evolution coefficient.

[F1 7.2.3.3. For diesel, ethanol (ED95), petrol, E85, LNG ₂₀ , LNG and LPG fuelled engines, including dual-fuel engines, all those tests may be conducted with the applicable market fuels. However, at the manufacturer’s request, the reference fuels specified in Annex IX may be used. This implies tests, as described in Section 1 of this Annex, with at least two of the reference fuels for each LPG or LNG engine, including dual-fuel engines. U.K.

Textual Amendments

F1 Substituted by Commission Regulation (EU) No 133/2014 of 31 January 2014 amending, for the purposes of adapting to technical progress as regards emission limits, Directive 2007/46/EC of the European Parliament and of the Council, Regulation (EC) No 595/2009 of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011 (Text with EEA relevance).

7.2.3.4. For CNG engines, including dual-fuel engines, all those tests may be conducted with market fuel in the following way: U.K.

(a)

for H marked engines with a market fuel within the H-range (0,89 ≤ S _λ ≤ 1,00);

(b)

for L marked engines with a market fuel within the L-range (1,00 ≤ S _λ ≤ 1,19);

(c)

for HL marked engines with a market fuel within the extreme range of the λ-shift factor (0,89 ≤ S _λ ≤ 1,19).

However, at the manufacturer’s request, the reference fuels specified in Annex IX may be used. This implies tests as described in Section 1 of this Annex.

7.2.3.5. Non-compliance of gas and dual-fuel engines U.K.

In the case of a dispute caused by the non-compliance of gas fuelled engines, including dual-fuel engines, when using a market fuel, the tests shall be performed with each reference fuel on which the parent engine has been tested, and with the possible additional third fuel as referred to in points 1.1.4.1 and 1.2.1.1 on which the parent engine may have been tested. Where applicable, the result shall be converted by a calculation applying the relevant factors ‘r’, ‘r _a ’ or ‘r _b ’ as described in points 1.1.5, 1.1.6.1 and 1.2.1.2. If r, ra or rb are less than 1, no correction shall take place.
