be extended to different vehicle types, provided that the vehicle, engine or pollution control system parameters specified below are identical or remain within the prescribed tolerances:
              7.3.1.1. Vehicle:
                Inertia category: the two inertia categories immediately above and any inertia category below.
                Total road load at 80 km/h: +5 per cent above and any value below.
              7.3.1.2. Engine
                   (a) Engine cylinder capacity (15 per cent);
                   (b) Number and control of valves;
                   (c) Fuel system;
                   (d) Type of cooling system;
                   (e) Combustion process.
              7.3.1.3. Pollution control system parameters:
                   (a) Catalytic converters and particulate filters:
                    (i) Number of catalytic converters, filters and elements;
                    (ii) Size of catalytic converters and filters (volume of monolith   ±10 per cent);
                    (iii) Type of catalytic activity (oxidizing, three-way, lean NOx trap,   SCR, lean NOx catalyst or other);
                    (iv) Precious metal load (identical or higher);
                    (v) Precious metal type and ratio (±15 per cent);
                    (vi) Substrate (structure and material);
                    (vii) Cell density;
                   (viii) Temperature variation of no more than 50 K at the inlet of the  catalytic converter or filter. This temperature variation shall               be checked under stabilized conditions at a speed of 120 km/h               and the load setting of the Type I test.
                   (b) Air injection:
                  (i) With or without;

                  (ii) Type (pulsair, air pumps, other(s)).
                (c) EGR:
                  (i) With or without;
                  (ii) Type (cooled or non cooled, active or passive control, high                 pressure or low pressure).
              7.3.1.4. The durability test may be carried out using a vehicle, which has a different body style, gear box (automatic or manual) and size of the wheels or tyres, from those of the vehicle type for which the type approval is sought.
              7.4.  Extensions for on-board diagnostics
              7.4.1.  The type approval shall be extended to different vehicles with identical engine and emission control systems as defined in Annex 11, Appendix 2. The type approval shall be extended regardless of the following vehicle characteristics:
                (a) Engine accessories;

                (b) Tyres;

                (c) Equivalent inertia;

                (d) Cooling system;

                (e) Overall gear ratio;

                (f) Transmission type; and

                (g) Type of bodywork.

  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 gaseous and particulate pollutants by the engine, emissions from the crankcase and evaporative emissions, to the vehicle type approved. The conformity of production procedures shall comply with those set out in the 1958 Agreement, Appendix 2 (E/ECE/324-E/ECE/TRANS/505/Rev.2), with the following requirements set out in the paragraphs below.
              8.1.1.  Where applicable the tests of Types I, II, III, IV and the test for OBD shall be performed, as described in Table A to this Regulation. The specific procedures for conformity of production are set out in the paragraphs 8.2.
