              5.3.5.2.1. Notwithstanding the requirements of paragraph 5.3.5.2., for each pollutant, not more than one of the three results obtained may exceed the limit prescribed by not more than 10 per cent, provided the arithmetical mean value 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.
              5.3.5.2.2. The number of tests prescribed in paragraph 5.3.5.2. may, at the request of the manufacturer, be increased to 10 if the arithmetical mean of the first three results is lower than 110 per cent of the limit. In this case, the requirement after testing is only that the arithmetical mean of all 10 results shall be less than the limit value.
              5.3.5.3. The number of tests prescribed in paragraph 5.3.5.2. may be reduced according to paragraphs 5.3.5.3.1. and 5.3.5.3.2.
              5.3.5.3.1. Only one test is performed if the result obtained for each pollutant of the first test is less than or equal to 0.70 L.
              5.3.5.3.2. If the requirement of paragraph 5.3.5.3.1. is not satisfied, only two tests are performed if for each pollutant the result of the first test is less than or equal to 0.85 L and the sum of the first two results is less than or equal to 1.70 L and the result of the second test is less than or equal to L.
(V1 ≤ 0.85 L and V1 + V2 ≤ 1.70 L and V2 ≤ L).
              5.3.6. Type V test (Durability of anti-pollution devices)
              5.3.6.1. This test shall be carried out on all vehicles referred to in paragraph 1 to which the test specified in paragraph 5.3.1. applies. The test represents an ageing test of 160,000 km driven in accordance with the programme described in Annex 9 on a test track, on the road or on a chassis dynamometer.
              5.3.6.1.1. Vehicles that can be fuelled either with petrol or with LPG or NG should be tested in the Type V test on petrol only. In that case the deterioration factor found with unleaded petrol will also be taken for LPG or NG.
              5.3.6.2. Notwithstanding the requirement of paragraph 5.3.6.1., a manufacturer may choose to have the deterioration factors from the following table used as an alternative to testing to paragraph 5.3.6.1.
