volume of charcoal shall be within 10 per cent of that for which the BWC300 was determined);

                  (g) Purge control system (for example, type of valve, purge control strategy).

              The manufacturer shall demonstrate the technical equivalence of points (b) and (c) to the responsible authority.

              6.6.3.2. The vehicle shall be considered to produce worst-case evaporative emissions and shall be used for testing if it has the largest ratio of fuel tank capacity to BWC300 within the family. The vehicle selection shall be agreed in advance with the responsible authority.

              6.6.3.3. The use of any innovative system calibration, configuration, or hardware related to the evaporative control system shall place the vehicle model in a different family.

              6.6.4. The responsible authority shall not grant type approval if the information provided is insufficient to demonstrate that the evaporative emissions are effectively limited during the normal use of the vehicle.

              6.7. Type 5 test (Description of the endurance test for verifying the durability of pollution control devices)

              6.7.1. This test shall be carried out on all vehicles referred to in paragraph 1. to which the test specified in paragraph 6.3. applies. The test represents an ageing test up to the target useful life driven in accordance with the programme described in Annex C4 to this Regulation on a test track, on the road or on a chassis dynamometer.

              For Level 1A;

              The target useful life is 160,000 km.

              For Level 1B;

              The target useful life is 80,000 km. For vehicles having engine displacement less than or equal to 0.660 litre, vehicle length less than or equal to 3.40 m, vehicle width less than or equal to 1.48 m, and vehicle height less than or equal to 2.00 m, seats less than or equal to 3 in addition to a driver, and payload less than or equal to 350 kg the target useful life is 60,000 km.

              6.7.1.1. Vehicles that can be fuelled either with petrol or with LPG or NG should be tested in the Type 5 test on petrol only. In that case the deterioration factor found with unleaded petrol will also be taken for LPG or NG.

              6.7.1.2. Special requirements for hybrid vehicles are provided in Appendix 4 to Annex C4.

              6.7.2. Notwithstanding the requirement of paragraph 6.7.1., a manufacturer may choose to have the deterioration factors from Tables 3a or 3b (as applicable) used as an alternative to testing to paragraph 6.7.1.
