              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 NOX after treatment device reaches a sufficiently high temperature for efficient operation within 400 seconds after a cold start at -7 °C as described in Type VI test.
                In addition, the manufacturer shall provide the Approval Authority with information on the operating strategy of the exhaust gas recirculation system (EGR), including its functioning at low temperatures.
                This information shall also include a description of any effects on emissions.
                The Approval Authority shall not grant type approval if the information provided is insufficient to demonstrate that the after treatment device actually reaches a sufficiently high temperature for efficient operation within the designated period of time.
              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 test. The Part One test is described in paragraph 6.1.1. of Annex 4a, and illustrated in figure 1 of the same annex. The low ambient temperature
