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 2.16., 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 to conduct a running-in procedure ('x' km, where x ≤ 15,000 km), it may be carried out as follows:

         The emissions of CO2 will be measured at zero and at 'x' km on the first tested vehicle (which can be the type approval vehicle);
         The evolution coefficient (EC) of the emissions between zero and 'x' km will be calculated as follows:

         The value of EC may be less than 1.

         The following vehicles will not be subjected to the running-in procedure, but their zero km emissions will be modified by the evolution coefficient, EC.

         In this case, the values to be taken will be:

         The value at 'x' km for the first vehicle;

         The values at zero km multiplied by the evolution coefficient for the following vehicles.

        9.3.1.1.2.3. As an alternative to this procedure, the car manufacturer can use a fixed evolution coefficient, EC, of 0.92 and multiply all values of CO2 measured at zero km by this factor.

        9.3.1.1.2.4. The reference fuels described in Annex 9 of Regulation No. 83 shall be used for this test.

        9.3.2. Conformity of production when manufacturer's statistical data is available.

        9.3.2.1. The following sections describe the procedure to be used to verify the CO2 conformity of production requirements when the manufacturer's production standard deviation is satisfactory.
