APPENDIX 1

      Definitions used in this standard for omnibuses, and medium and heavy goods vehicles 'designed for off-road use'

 1.                                  Omnibuses with a 'Gross Vehicle Mass' not exceeding 12 tonnes and medium goods vehicles
     1.                            Category MD vehicles, category ME vehicles with a 'Gross Vehicle Mass' not exceeding 12 tonnes, and category NB vehicles are considered to be 'designed for off-road use' if all their wheels are designed to be driven simultaneously, including vehicles where the drive to one axle can be disengaged, or if the following three criteria are satisfied:
            1.       At least one front axle and at least one rear axle are designed to be driven simultaneously, including vehicles where the drive to one axle can be disengaged; and
            2.       There is at least one differential locking mechanism or at least one mechanism having a similar effect; and
            3.       They can climb a 25 per cent gradient calculated for a solo vehicle.

 1.                                  Omnibuses with a 'Gross Vehicle Mass' exceeding 12 tonnes and heavy goods vehicles
     1.                            Category ME vehicles with a 'Gross Vehicle Mass' exceeding 12 tonnes and category NC vehicles are considered to be 'designed for off-road use' if all of the following criteria are satisfied:
            1.       All wheels are driven, except where applicable, when the drive to one 'Axle' is disengaged; and
            2.       There is at least one differential locking mechanism or at least one mechanism having a similar effect; and
            3.       They can climb a 25 per cent gradient calculated for a solo vehicle; and
            4.       At least four of the following six criteria are satisfied:
                  1.         The 'Approach Angle' is at least 25°;
                  2.       The 'Departure Angle' is at least 25°;
                  3.    The 'Breakover Angle' is at least 25°;
                  4.     The 'Ground Clearance' under the front axle is at least 250 mm;
                  5.       The 'Ground Clearance' between the axles is at least 300 mm;
                  6.     The 'Ground Clearance' under the rear axle is at least 250 mm.

 2.                                  Load and checking conditions
     1.                            The measurements referred to clause 2.1 of this appendix are determined with the vehicle loaded to its 'Gross Vehicle Mass'.
     2.                            When measuring the 'Approach Angle' and the 'Departure Angle', no account is taken of underrun protective devices.
