in accordance with the specifications in Annex B3 may be used for the Type 1 test.

              In the case that a fail decision for the accuracy of OBFCM is concluded based on tests conducted using commercial fuel, the tests shall be repeated using reference fuel and only the decision from the repeated tests shall be valid.

              For Level 1B:

              All remaining tests shall be conducted with reference fuels in accordance with the specifications in Annex B3 for the Type 1 test. However, at the request of the manufacturer the mileage accumulation for the run-in in paragraph 1.7. of Appendix 3 may be conducted with commercial fuel.

              8.2.5.2. Tests for conformity of production of vehicles fuelled by LPG or NG/biomethane may be performed with a commercial fuel of which the C3/C4 ratio lies between those of the reference fuels in the case of LPG, or of one of the high or low caloric fuels in the case of NG/biomethane. In all cases a fuel analysis shall be presented to the responsible authority.

              8.2.6. Criteria for validity of speed trace tolerances and drive trace indices of the Type 1 CoP test

              The speed trace tolerances and drive trace indices shall fulfil the criteria specified in paragraph 2.6.8.3. of Annex B6.

              8.3. Checking the conformity for a Type 4 test

              8.3.1. The production shall be deemed to conform if the vehicle selected and tested according to paragraph 8.1.5. meets the requirements of paragraph 6.6.2., or the requirements of Appendix 4 as applicable.

              8.3.2. If the vehicle tested does not satisfy the requirements of paragraph 8.3.1., a further random sample of four vehicles shall be taken from the same family without unjustified delay and subjected to the Type 4 test described in Annex C3 or as an alternative at least the tests described in Appendix 4.

              The production shall be deemed to conform if the requirements are met for at least three of these vehicles within 6 months after the initial failed test has been detected.

              8.3.3. If the vehicles tested do not satisfy the requirements of paragraph 8.3.2., a further random sample shall be taken from the same family without unjustified delay and subjected to the Type 4 test described in Annex C3.

              If the vehicle tested does not satisfy the requirements of Annex C3, a further random sample of four vehicles shall be taken from the same family and also subjected without unjustified delay to the Type 4 test described in Annex C3.

              On request of the manufacturer, for CoP tests described in Annex C3 the Permeability Factor (PF) derived at Type Approval or the Assigned Permeability Factor (APF) may be applied.

              The production shall be deemed to conform if the requirements
