be fuelled either with petrol or with LPG or NG/biomethane shall be tested in the Type 2 test on both fuels.
              5.3.2.1.2. Notwithstanding the requirement of paragraph 5.3.2.1.1., mono-fuel gas vehicles will be regarded for the Type 2 test as vehicles that can only run on a gaseous fuel.
              5.3.2.2. For the Type 2 test set out in Annex 5 to this Regulation, 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 3 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 3 test on petrol only.
              5.3.3.1.2. Notwithstanding the requirement of paragraph 5.3.3.1.1., mono-fuel gas vehicles will be regarded for the Type 3 test as vehicles that can only run on a gaseous fuel.
              5.3.3.2. When tested in accordance with Annex 6 to this Regulation, the engine's crankcase ventilation system shall not permit the emission of any of the crankcase gases into the atmosphere.
              5.3.4. Reserved
              5.3.5. Type 6 test (Verifying the average exhaust emissions of carbon monoxide and hydrocarbons after a cold start at low ambient temperature).
              5.3.5.1. This test shall be carried out on all vehicles referred to in paragraph 1. except those having compression-ignition engines.
              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 NEDC based Type I test. The Part One test is described in paragraph 6.1.1. of Annex 4a to the 07 series of amendments to this Regulation, and illustrated in Figure A4a/1 of the same annex. The low ambient temperature test lasting a total of 780 seconds shall be carried out without interruption and start at engine cranking.
              5.3.5.1.3. The low ambient temperature test shall be carried out at an ambient test temperature of 266 K (-7 °C). Before the test is carried out, the test vehicles shall be conditioned in a uniform manner to ensure that the test results may be reproducible. The conditioning and other test procedures are carried out as described in Annex 8 to
