The run-in factor RIFE(j) for fuel efficiency and RIEC(j) for electric energy consumption shall be determined according to the procedure specified in paragraphs 1.9. (excluding paragraph 1.9.1.) and 1.10. of this appendix, where CO2 in the formulae is replaced by FE and EC respectively.

              2. For Level 1B only

              Prior to the application of the derived run-in factor for fuel efficiency, the manufacturer shall provide the following information to the responsible authority:

                  (a) evidence of the derived run-in factor including the existence of statistical significance regarding the fit of the slope;

                  (b) an explanation of the validation method to be used after the start of production, e.g. by measuring the run-in factor from selected vehicle(s) from the plant and then evaluating whether the run-in factor is appropriate or not.

Appendix 4

Conformity of production for Type 4 test
              1. For routine end-of-production-line testing, as an alternative to conducting the Type 4 test as described in Annex C3 the holder of the approval may demonstrate compliance by sampling vehicles which shall meet the requirements in paragraphs 2. to 4. of this appendix.

              1.1. In case of vehicles with a sealed fuel tank system, at the request of the manufacturer and in agreement with the responsible authority, alternative procedures to paragraphs 2. to 4. of this appendix can be applied.

              1.2. When the manufacturer chooses to use any alternative procedure, all the details of the conformity test procedure shall be recorded in the type approval documentation.

              2. Test for leakage

              2.1. Vents to the atmosphere from the emission control system shall be isolated.

              2.2. A pressure of 3.70 kPa  0.10 kPa shall be applied to the fuel system. At the request of manufacturer and with approval of the responsible authority, an alternative pressure can also be applied, taking into account the pressure range in use of the fuel system.

              2.3. The pressure shall be allowed to stabilise prior to isolating the fuel system from the pressure source.

              2.4. Following isolation of the fuel system, the pressure shall not drop by more than 0.50 kPa in five minutes.

              2.5. At the request of the manufacturer and in agreement with the responsible authority the function for leakage can be demonstrated by an equivalent alternative procedure.

              3. Test for venting

              3.1. Vents to the atmosphere from the emission control shall be isolated.

              3.2. A pressure of 3.70 kPa  0.10 kPa shall be applied to the fuel system. At the request of manufacturer and with approval of the responsible authority, an alternative pressure can also be applied, taking into account the pressure range in use of the fuel system.

              3.3. The pressure shall be allowed to stabilise prior to isolating the fuel system from
