7.1.4.1. Identical parameters for extending approval are:
                   (a) Engine;
                   (b) Combustion process;
                   (c) Periodically regenerating system (i.e. catalyst, particulate trap);
                   (d) Construction (i.e. type of enclosure, type of precious metal, type of substrate, cell density);
                   (e) Type and working principle;
                   (f) Dosage and additive system;
                   (g) Volume ±10 per cent;
                   (h) Location (temperature ±50 °C at 120 km/h or 5 per cent difference of max. temperature/pressure).
              7.1.4.2. Use of Ki factors for vehicles with different reference masses
                The Ki factors developed by the procedures in paragraph 3. of Annex 13 of this Regulation for type approval of a vehicle type with a periodically regenerating system, may be used by other vehicles which meet the criteria referred to in paragraph 7.1.4.1. and have a reference mass within the next two higher equivalent inertia classes or any lower equivalent inertia.
              7.1.5.  Application of extensions to other vehicles
                When an extension has been granted in accordance with paragraphs 7.1.1. to 7.1.4., such a type approval shall not be further extended to other vehicles.
              7.2.  Extensions for evaporative emissions (Type IV test)
              7.2.1.  The type approval shall be extended to vehicles equipped with a control system for evaporative emissions which meet the following conditions:
              7.2.1.1. The basic principle of fuel/air metering (e.g. single point injection,) is the same.
              7.2.1.2. The shape of the fuel tank and the material of the fuel tank and liquid fuel hoses is identical.
              7.2.1.3. The worst-case vehicle with regard to the cross-paragraph and approximate hose length shall be tested. Whether non-identical vapour/liquid separators are acceptable is decided by the Technical Service responsible for the type approval tests.
              7.2.1.4. The fuel tank volume is within a range of ±10 per cent.
              7.2.1.5. The setting of the fuel tank relief valve is identical.
              7.2.1.6. The method of storage of the fuel vapour is identical, i.e. trap form and volume, storage medium, air cleaner (if used for evaporative emission control), etc.
              7.2.1.7. The method of purging the stored vapour is identical (e.g. air flow, start point or purge volume over the preconditioning cycle).
              7.2.1.8. The method of sealing and venting the fuel metering system is identical.
              7.2.2.  The type approval shall be extended to vehicles with:
              7.2.2.1. Different engine sizes;
              7.2.2.2. Different engine powers;
              7.2.2.3. Automatic and manual gearboxes;
              7.2.2.4. Two and four wheel transmissions;
              7.2.2.5. Different body styles; and
              7.2.2.6. Different wheel and tyre sizes.
              7.3.  Extensions for durability of pollution control devices (Type V test)
              7.3.1.  The type approval shall 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
