that can be fuelled either with petrol or with LPG or NG/biomethane shall be tested in the test Type II on both fuels.
              5.3.2.1.2. Notwithstanding 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.  For the Type II test set out in Annex 5, at normal engine idling speed, the maximum permissible carbon monoxide content in the exhaust gases shall be that stated by the vehicle manufacturer. However, the maximum carbon monoxide content shall not exceed 0.3 per cent vol.

                At high idle speed, the carbon monoxide content by volume of the exhaust gases shall not exceed 0.2 per cent, with the engine speed being at least 2,000 min-1 and Lambda being 1 ±0.03 or in accordance with the specifications of the manufacturer.

              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/biomethane.
              5.3.4.1.1. Vehicles that can be fuelled either with petrol or with LPG or with NG/biomethane 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 not be applied to compression ignition vehicles.
                 However, for compression ignition vehicles when applying for type approval, manufacturers shall present to the Approval Authority information showing that the
