of Annex 4a of Regulation No. 83, until the end of the test criteria is reached.

         4.2.2.2.2. To measure the OVC range the end of the test criteria is reached when the battery has reached its minimum state of charge according to the criteria defined in Annex 8, paragraph 3.2.3.2.2. or 4.2.4.2.2. Driving is continued until the final idling period in the extra-urban cycle.

         4.2.2.2.3. To respect human needs, up to three interruptions are permitted between test sequences, of no more than fifteen minutes in total.

         4.2.2.2.4. At the end, the total distance driven in km, rounded to the nearest whole number, is the OVC range of the hybrid electric vehicle.

       EMISSIONS TEST PROCEDURE FOR A VEHICLE EQUIPPED
       WITH A PERIODICALLY REGENERATING SYSTEM

        1. INTRODUCTION

       1.1.                           This annex defines the specific provisions regarding type approval of a vehicle equipped with a periodically regenerating system as defined in paragraph 2.19 of this Regulation.

       2. SCOPE AND EXTENSION OF THE TYPE APPROVAL

       2.1. Vehicle family groups equipped with periodically regenerating system

        The procedure applies to vehicles equipped with a periodically regenerating system as defined in paragraph 2.19. of this Regulation.  For the purpose of this annex vehicle family groups may be established.  Accordingly, those vehicle types with regenerative systems, whose parameters described below are identical, or within the stated tolerances, shall be considered to belong to the same family with respect to measurements specific to the defined periodically regenerating systems.

       2.1.1. Identical parameters are:

        Engine:
        (a) Number of cylinders,
        (b) Engine capacity (±15 per cent),
        (c) Number of valves,
        (d) Fuel system,
        (e) Combustion process (2 stroke, 4 stroke, rotary).

        Periodically regenerating system (i.e. catalyst, particulate trap):
        (a) Construction (i.e. type of enclosure, type of precious metal, type of substrate,  cell density),
        (b) Type and working principle,
        (c) Dosage and additive system,
        (d) Volume (±10 per cent),
        (e) Location (temperature ±50 °C at 120 km/h or 5 per cent difference of maximum               temperature / pressure).

       2.2. Vehicle types of different reference masses

        The Ki factor developed by the procedures in this annex for type approval of a vehicle type with a periodically regenerating system as defined in paragraph 2.19. of this Regulation, may be extended to other vehicles in the family group with a reference mass within the next two higher equivalent inertia classes or any lower equivalent inertia.

2.3. Instead of carrying out the test procedures defined in the following paragraph, a fixed Ki value of 1.05 may be used, if the technical service sees no reason that this value could be exceeded.

       3. TEST PROCEDURE

        The vehicle may be equipped with a switch capable of preventing or permitting the regeneration process provided that this operation has no effect
