of paragraph 3.0.1. (c) of UN Regulation No. 154.
              7.2. Extensions for low temperature test (Type 6 test)
              7.2.1. Vehicles with different reference masses
              7.2.1.1. The type approval shall be extended only to vehicles with a reference mass requiring the use of the next two higher equivalent inertia or any lower equivalent inertia.
              7.2.1.2. For category N vehicles, the approval shall be extended only to vehicles with a lower reference mass, if the emissions of the vehicle already approved are within the limits prescribed for the vehicle for which extension of the approval is requested.
              7.2.2. Vehicles with different overall transmission ratios
              7.2.2.1. The type approval shall be extended to vehicles with different transmission ratios only under certain conditions.
              7.2.2.2. To determine whether type approval can be extended, for each of the transmission ratios used in the Type 6 test, the proportion,
              (E) = (V2 – V1)/V1
              shall be determined where, at an engine speed of 1,000 min –1 , V1 is the speed of the vehicle-type approved and V2 is the speed of the vehicle type for which extension of the approval is requested.
              7.2.2.3. If, for each transmission ratio, E ≤ 8 per cent, the extension shall be granted without repeating the Type 6 test.
              7.2.2.4. If, for at least one transmission ratio, E > 8  per cent, and if, for each gear ratio, E ≤ 13  per cent, the Type 6 test shall be repeated. The tests may be performed in a laboratory chosen by the manufacturer subject to the approval of the Technical service. The report of the tests shall be sent to the Technical service responsible for the type approval tests.
              7.2.3. Vehicles with different reference masses and transmission ratios
               The type approval shall be extended to vehicles with different reference masses and transmission ratios, provided that all the conditions prescribed in paragraphs 7.2.1. and 7.2.2. are fulfilled.
              8. Conformity of production (COP)
              8.1. Every vehicle bearing an approval mark as prescribed under this Regulation shall conform, with regard to components affecting the emission of pollutants by the engine and emissions from the crankcase, to the vehicle type approved. The conformity of production procedures shall comply with those set out in the 1958 Agreement, Schedule 1 (E/ECE/TRANS/505/Rev.3), with the following requirements:
              8.1.1. Where applicable the Type 2 and 3 test, as described in Table A of this Regulation, shall be performed. The specific procedures for conformity of production are set out in the paragraph 8.2.
              8.2. Checking the conformity of the vehicle for a Type 3 test.
              8.2.1. If a verification of the Type 3 test is to be carried out, it shall be conducted in accordance with the following requirements:
              8.2.1.1. When the type
