                  (1) For compression-ignition engines.
                  (2) Except vehicles the maximum mass of which exceeds 2,500 kg.
                  (3) And those category M vehicles which are specified in note (2).

           5.3.1.4.1. Notwithstanding the requirements of paragraph 5.3.1.4., for each pollutant or combination of pollutants, one of the three resulting masses obtained may exceed, by not more than 10 per cent, the limit prescribed, provided the arithmetical mean of the three results is below the prescribed limit. Where the prescribed limits are exceeded for more than one pollutant, it is immaterial whether this occurs in the same test or in different tests.

           5.3.1.4.2. When the tests are performed with gaseous fuels, the resulting mass of gaseous emissions shall be less than the limits for petrol-engined vehicles in the above table.

           5.3.1.5. The number of tests prescribed in paragraph 5.3.1.4. is reduced in the conditions hereinafter defined, where V1 is the result of the first test and V2 the result of the second test for each pollutant or for the combined emission of two pollutants subject to limitation.

           5.3.1.5.1. Only one test is performed if the result obtained for each pollutant or for the combined emission of two pollutants subject to limitation, is less than or equal to 0.70 L (i.e. V1  0.70 L).

           5.3.1.5.2. If the requirement of paragraph 5.3.1.5.1. is not satisfied, only two tests are performed if, for each pollutant or for the combined emission of two pollutants subject to limitation, the following requirements are met:

           V1  0.85 L and V1 + V2  1.70 L and V2  L.

           5.3.2.  Type II test (Carbon monoxide emission test at idling speed)

           5.3.2.1.  This test is carried out on all vehicles powered by positive-ignition engines having a maximum mass exceeding 3.5 tonnes.

           5.3.2.1.1. Vehicles that can be fuelled either with petrol or with LPG or NG 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
