special provisions shall apply, if applicable.

         7.1.  Exhaust emission related extensions
         (Type I, Type II and Type VI tests).

         7.1.1.  Vehicle types of different reference masses

         7.1.1.1. Approval granted to a vehicle type may be extended only to vehicle types of a reference mass requiring the use of the next two higher equivalent inertia categories or any lower equivalent inertia category.

         7.1.1.2. In the case of vehicles of category N1 and vehicles of category M referred to in note 2 of paragraph 5.3.1.4., if the reference mass of the vehicle type for which extension of the approval is requested requires the use of equivalent inertia lower than that used for the vehicle type already approved, extension of the approval is granted if the masses of the pollutants obtained from the vehicle already approved are within the limits prescribed for the vehicle for which extension of the approval is requested.

         7.1.2.  Vehicle types with different overall gear ratios

         Approval granted to a vehicle type may under the following conditions be extended to vehicle types which differ from the type approved only in respect of their transmission ratios:

         7.1.2.1. For each of the transmission ratios used in the Type I and Type VI test, it is necessary to determine the proportion,

         where, at an engine speed of 1,000 rpm, 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.

         7.1.2.2.  If, for each gear ratio, E  8 per cent, the extension is granted without repeating the Type I and Type VI tests.

         7.1.2.3.  If, for at least one gear ratio, E > 8 per cent and if for each gear ratio E  13 per cent the Type I and Type VI test shall be repeated, but 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.

         7.1.3.  Vehicle types of different reference masses and different overall transmission ratios

         Approval granted to a vehicle type may be extended to vehicle types differing from the approved type only in respect of their reference mass and their overall transmission ratios, provided that all the conditions prescribed in paragraphs 7.1.1. and 7.1.2. are fulfilled.

         7.1.4.  Note:  When a vehicle type has been approved in accordance with paragraphs 7.1.1. to 7.1.3., such approval may not be extended to other vehicle types.

         7.2.  Evaporative emissions (Type IV test)

         7.2.1. Approval granted to a vehicle type equipped with a control system for evaporative emissions may be extended under the following conditions:

         7.2.1.1. The basic principle
