the requirement of paragraph 5.3.2.1.1., vehicles that can be fuelled with either petrol or a gaseous fuel, but where the petrol system is fitted for emergency purposes or starting only and which the petrol tank cannot contain more than 15 litres of petrol will be regarded for the test Type II as vehicles that can only run on a gaseous fuel.

           5.3.2.2. When tested in accordance with Annex 5, the carbon monoxide content by volume of the exhaust gases emitted with the engine idling shall not exceed 3.5 per cent at the setting specified by the manufacturer and shall not exceed 4.5 per cent within the range of adjustments specified in that Annex.

           5.3.3. Type III test (verifying emissions of crankcase gases)

           5.3.3.1. This test shall be carried out on all vehicles referred to in paragraph 1. except those having compression-ignition engines.

           5.3.3.1.1. Vehicles that can be fuelled either with petrol or with LPG or NG should be tested in the Type III test on petrol only.

           5.3.3.1.2. Notwithstanding the requirement of paragraph 5.3.3.1.1., vehicles that can be fuelled with either petrol or a gaseous fuel, but where the petrol system is fitted for emergency purposes or starting only and which the petrol tank cannot contain more than 15 litres of petrol will be regarded for the test Type III as vehicles that can only run on a gaseous fuel.

           5.3.3.2. When tested in accordance with Annex 6, the engine's crankcase ventilation system shall not permit the emission of any of the crankcase gases into the atmosphere.

           5.3.4. Type IV test (Determination of evaporative emissions)

           5.3.4.1. This test shall be carried out on all vehicles referred to in paragraph 1. except those vehicles having a compression-ignition engine, vehicles fuelled with LPG or NG and those vehicles with a maximum mass greater than 3,500 kg.

           5.3.4.1.1. Vehicles that can be fuelled either with petrol or with LPG or NG should be tested in the Type IV test on petrol only.

           5.3.4.2. When tested in accordance with Annex 7, evaporative emissions shall be less than 2 g/test.

           5.3.5. Type VI test (Verifying the average low ambient temperature carbon monoxide and hydrocarbon exhaust emissions after a cold start).

           5.3.5.1. This test shall be carried out on all M1 and N1 Class I vehicles equipped with a positive-ignition engine, except vehicles designed to carry more than six occupants and vehicles whose maximum mass exceeds 2,500 kg.

           5.3.5.1.1. The vehicle is placed on a chassis dynamometer equipped with a means of load an inertia simulation.

           5.3.5.1.2. The test consists of the four elementary urban driving cycles of Part One of the Type I
