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 vehicle shall be a new vehicle, or a used test vehicle for which at least all of the following components are newly installed simultaneously:

                  (a) Internal combustion engine;
                  (b) Driveline components (at least, but not limited to, transmission, tyre, axles, etc.);
                  (c) Brake components;
                  (d) For Level 1A only: REESSs for EVs;
                  (e) For Level 1A only: Exhaust system;
                and any other component that has a non-negligible influence on criteria emissions, CO2 emissions, fuel efficiency and electric energy consumption.
               For the new vehicle, or the used vehicle for which the above mentioned components have been replaced, the system odometer of the test vehicle Ds in km shall be recorded.

              1.4. At the request of the manufacturer and with approval by the responsible authority, it is allowed to perform the run-in procedure on multiple test vehicles. In this case, the valid test results of all tested vehicles shall be considered for the determination of the run-in factors.

              1.5. Chassis dynamometer setting

              1.5.1. The chassis dynamometer shall be set to the target road load for the test vehicle, according to the procedure specified in paragraph 7. of Annex B4.

               The chassis dynamometer shall be set independently prior to each test before the run-in mileage accumulation and shall be set once for the post-run-in tests after the run-in mileage accumulation.

              1.5.2. For Level 1B only:

               It is allowed to apply the same dynamometer setting value which was generated during type approval testing for all testing.

              1.6. Before the run-in, the test vehicle shall be tested according to the Type 1 test procedure specified in Annex B6 and Annex B8. The test shall be repeated until three valid test results have been obtained. Drive trace indexes shall be calculated according to paragraph 7. of Annex B7 and these shall fulfil the criteria specified in paragraph 2.6.8.3.1.4. of Annex B6. The system odometer setting Di shall be recorded prior to each test. The measured criteria emissions, CO2 emissions, fuel efficiency and electric energy consumption shall be calculated according to Step 4a of Table A7/1 in Annex B7 or Step 4a of Table A8/5 in Annex B8.

               For Level 1A only:

               The signal of the acceleration control position shall be recorded during all tests at a sampling frequency of 10 Hz. It is allowed to use the OBD acceleration control position signal for this purpose. The responsible authority may request the manufacturer to evaluate this signal to ensure that the test result is performed correctly.

              1.7.
