The Manufacturer shall implement adequate arrangements and documented control plans and carry-out at specified intervals as given in this regulation the necessary emission and OBD tests to verify continued conformity with the approved type. The approval authority shall verify and agree with these arrangements and control plans of the manufacturer and perform audits and conduct emission and OBD tests at specific intervals, as given in this regulation, at the premises of the manufacturer, including production and test facilities as part of the product conformity and continued verification arrangements as described in Annex X of Directive 2007/46/EC. U.K.

4.1.2. The manufacturer shall check the conformity of production by testing the emissions of pollutants (given in Table 2 of Annex I to Regulation (EC) No 715/2007), the emission of CO₂ (along with the measurement of electric energy consumption, EC), the crankcase emissions, evaporative emissions and the OBD. The verification shall therefore include the tests of types 1, 3, 4 and the test for OBD, as described in section 2.4 of this Annex and the relevant annexes quoted therein. The specific procedures for conformity of production are set out in Sections 4.2 to 4.7 and Appendixes 1 and 2. U.K.

4.1.3. For the purposes of the manufactures conformity of production check, the family means the CO₂ interpolation family for tests of Type 1 and 3, includes for the Type 4 test the extensions described in paragraph 3.2 of this Annex and the OBD family with the extensions described in paragraph 3.3 of this Annex for the OBD tests. U.K.

4.1.4. The frequency for product verification performed by the manufacturer shall be based on a risk assessment methodology consistent with the international standard ISO 31000:2009 — Risk Management — Principles and guidelines and at least for Type 1 with a minimum frequency of one verification per 5 000 vehicles produced per family or once per year, whichever comes first. U.K.

4.1.5. The Approval Authority which has granted type-approval may at any time verify the conformity control methods applied in each production facility. U.K.

For the purpose of this regulation the Approval Authority shall perform audits for verifying the manufacturers arrangements and documented control plans at the premises of the manufacturer on a risk assessment methodology consistent with the international standard ISO 31000:2009 — Risk Management — Principles and guidelines and, in all cases, with a minimum frequency of one audit per year.

If the Approval Authority is not satisfied with the auditing procedure of the manufacturer, physical test shall directly be carried out on production vehicles as described in Sections 4.2 to 4.9.

4.1.6. The normal frequency of physical test verifications by the Approval Authority shall be based on the results of the auditing procedure of the manufacturer on a risk assessment methodology and in all cases with a minimum frequency of one verification test per three years. The Approval Authority shall conduct these physical emission tests and OBD tests on production vehicles as described in Sections 4.2 to 4.9. U.K.

In the case of the manufacturer running the physical tests, the Approval Authority shall witness the tests at the manufacturer's facility.

4.1.7. The Approval Authority shall report the results of all audit checks and physical tests performed on verifying conformity of the manufacturers and file it for a period of minimum 10 years. These reports should be available for other type approval authorities and the European Commission on request. U.K.

4.1.8. In case of non-conformity Article 30 of Directive 2007/46/EC shall apply. U.K.

4.2. Checking the conformity of the vehicle for a type 1 test U.K.

The limit values against which to check conformity for pollutants are set out in Table 2 of Annex I to Regulation (EC) No 715/2007. As regards CO₂ emissions, the limit value shall be the value determined by the manufacturer for the selected vehicle in accordance with the interpolation methodology set out in Sub-Annex 7 of Annex XXI. The interpolation calculation shall be verified by the approval authority. U.K.

4.2.2. A sample of three vehicles shall be selected at random in the family. After selection by the approval authority, the manufacturer shall not undertake any adjustment to the vehicles selected. U.K.

4.2.2.1. The selection shall only include finalised production vehicles which have completed a maximum of 80 km and those vehicles will be referred to as zero km vehicles for the purposes of checking conformity against Type 1 test. The vehicle shall be tested on the appropriate WLTP cycle as described in Annex XXI to this Regulation notwithstanding the requirements for test repetitions, or km of vehicles. The test results shall be the values after all corrections according to this regulation are applied. U.K.

4.2.3. The statistical method for calculating the test criteria is described in Appendix 1. U.K.

The production of a family shall be deemed to not conform when a fail decision is reached for one or more of the pollutants and CO₂ values, according to the test criteria in Appendix 1.

The production of a family shall be deemed to conform once a pass decision is reached for all the pollutants and CO₂ values according to the test criteria in Appendix 1.

When a pass decision has been reached for one pollutant, that decision shall not be changed by any additional tests carried out to reach a decision for the other pollutants and CO₂ values.

If a pass decision is not reached for all the pollutants and CO₂ values, a test shall be carried out on another vehicle, up to the maximum of 16 vehicles, and the procedure described in Appendix 1 for taking a pass or fail decision shall be repeated (see Figure I.4.2).

The running-in procedure shall be conducted by the manufacturer, who shall not to make any adjustments to these vehicles. U.K.

4.2.4.1. In order to establish a measured evolution coefficient with a run-in vehicle the procedure shall be as follows: U.K.

(b)

the evolution coefficient (EvC) of the pollutants/CO₂ between 80 km and ‘x’ km shall be calculated as:

(c)

the other vehicles in the interpolation family shall not be run in, but their zero km emissions/EC/CO₂ shall be multiplied by the evolution coefficient of the first run-in vehicle. In this case, the values to be taken for testing as in Appendix 1 shall be:

(i)

the values at ‘x’ km for the first vehicle;

(ii)

the values at zero km multiplied by the relevant evolution coefficient for the other vehicles.

4.2.4.2. All these tests shall be conducted with commercial fuel. However, at the manufacturer’s request, the reference fuels described in Annex IX may be used. U.K.

4.2.4.3. When checking the conformity of production for CO₂, as an alternative to the procedure mentioned in Section 4.2.4.1 the vehicle manufacturer may use a fixed evolution coefficient EvC of 0,98 and multiply all values of CO₂ measured at zero km by this factor. U.K.
