shall remain fully depressed until the reference curve has been reached again.

       4.2.1.4. To respect human needs, up to three interruptions are permitted between test sequences, of no more than 15 minutes in total.

       4.2.1.5. At the end, the measure De of the covered distance in km is the electric range of the electric vehicle.  It shall be rounded to the nearest whole number

       4.2.2. For hybrid electric vehicle

       4.2.2.1. The applicable test sequence and accompanying gear shift prescription, as defined in paragraph 1.4. of Annex 8, is applied on a chassis dynamometer adjusted as described in appendix 2, 3, and 4 of Annex 4 of Regulation No. 83, until the end of the test criteria is reached.

       4.2.2.2. The end of the test criteria is reached when the vehicle is not able to meet the target curve up to 50 km/h, or when an indication from the standard on-board instrumentation is given to the driver to stop the vehicle or when the fuel consuming engine starts up.  Then the vehicle shall be slowed down to 5 km/h by releasing the accelerator pedal, without touching the brake pedal and then stopped by braking.

       4.2.2.3. At a speed over 50 km/ h, when the vehicle does not reach the required acceleration or speed of the test cycle, the accelerator pedal shall remain fully depressed until the reference curve has been reached again.

       4.2.2.4. To respect human needs, up to three interruptions are permitted between test sequences, of no more than 15 minutes in total.

       4.2.2.5. At the end, the measure De of the covered distance in km is the electric range of the hybrid electric vehicle.  It shall be rounded to the nearest whole number.

       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 2.16. 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 2.16. 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):
