paragraph 9.1. are complied with, appropriate production checks shall be carried out.

       9.3. Vehicles powered by an internal combustion engine only:

       9.3.1. As a general rule, measures to ensure the conformity of production with regard to CO2 emissions from vehicles are checked on the basis of the description in the type approval certificate conforming to the model in Annex 4 of this Regulation.

        The control of production conformity is based on an assessment made by the competent authority of the manufacturer's auditing procedure in order to ensure conformity of the vehicle type with respect to the emission of CO2.

        If the authority is not satisfied with the standard of the manufacturer's auditing procedure, they may require that verification tests be carried out on vehicles in production.

       9.3.1.1. If a measurement of the emissions of CO2 must be carried out on a vehicle type that has had one or several extensions, the tests will be carried out on the vehicle(s) available at the time of the test (vehicle(s) described in the first document or in subsequent extensions).

       9.3.1.1.1. Conformity of the vehicle for the CO2 test.

       9.3.1.1.1.1. Three vehicles are randomly taken in the series and are tested according to the procedure as described in Annex 6.

       9.3.1.1.1.2. If the authority is satisfied with the production standard deviation given by the manufacturer, the tests are carried out according to paragraph 9.3.2.

        If the authority is not satisfied with the production standard deviation given by the manufacturer, the tests are carried out according to paragraph 9.3.3.

       9.3.1.1.1.3. The production of a series is regarded as conforming or non-conforming, on the basis of tests on the three sampled vehicles, once a pass or fail decision is reached for CO2, according to the test criteria applied in the appropriate table.

        If no pass or fail decision is reached for CO2, a test is carried out on an additional vehicle (see figure 1).

       9.3.1.1.1.4. In the case of periodically regenerating systems as defined in paragraph 2.19., the results shall be multiplied by the factor Ki obtained by the procedure specified in Annex 10 at the time when type approval was granted.

        At the request of the manufacturer, testing may be carried out immediately after a regeneration has been completed.

        9.3.1.1.2. Notwithstanding the requirements of Annex 6, the tests will be carried out on vehicles which have not travelled any distance.

        9.3.1.1.2.1. However, at the request of the manufacturer, the tests will be carried out on vehicles which have been run-in a maximum of 15,000 km.

         In this case, the running-in procedure will be conducted by the manufacturer who shall undertake not to make any adjustments to those vehicles.

        9.3.1.1.2.2. If the manufacturer asks
