the manufacturer and with the approval of the responsible authority, and with reasonable evidence and appropriate data,  may be changed.

              3.4. For Level 1A only:

               For vehicles referred to in paragraph 5.11. of this Regulation the conformity of production of OBFCM devices as defined in paragraph 4.2. of Appendix 5 shall be evaluated as follows:

                  (1) For each single test i performed for the purposes of paragraph 3. of this appendix the value xi shall be set equal to:

                  1 / (1 - Accuracy)

                  where the Accuracy of the OBFCM device shall be determined in accordance with paragraph 4.2. of Appendix 5.

                  (2) The conformity of production of the OBFCM devices shall be evaluated according to the requirements of paragraph 3.3.1., but applying a factor A value of 1.0526.

                  (3) If for the last test N performed for the purposes of paragraph 3. the decision (iii) of paragraph 3.3.1. with regard to the conformity of production of the OBFCM devices is reached, the sequence of tests shall be continued until a final decision (i) or (ii) of paragraph 3.3.1. is reached.

              The Type Approval authority shall keep a record of the determined accuracies of OBFCM device at each test as well as the decision according to paragraph 3.3.1. after each test.

Appendix 3

Run-in test procedure to determine run-in factors

              1. Description of test procedure for the determination of the run-in factors

              1.1. The run-in test procedure shall be conducted by the manufacturer, who shall not make any adjustments to the test vehicles that have an impact on the criteria emissions, CO2 emissions, fuel efficiency and electric energy consumption. The hardware and relevant ECU calibration of the test vehicle shall conform to the type approval vehicle. All the relevant hardware that has an impact on the criteria emissions, CO2 emissions, fuel efficiency and electric energy consumption shall have had no operation prior to the run-in test procedure.

              1.2. The test vehicle shall be configured as vehicle H within the CoP family.

               If the CoP family has multiple interpolation families, the test vehicle shall be configured as vehicle H of the interpolation family with the highest expected production volume within the CoP family. At the request of the manufacturer, and with approval of the responsible authority a different test vehicle may be selected.

              1.2.1. Extension of run-in factor

              At the request of the vehicle manufacturer and with approval by the responsible authority, the derived run-in factor for pollutant emissions, fuel efficiency and fuel consumption can be extended to other CoP families.

              The vehicle manufacturer shall provide evidence on the justification and technical criteria for merging these COP families, ensuring that there is a large similarity between those families.

              1.3. The test
