gradient calculated for a solo vehicle;
 at least four of the following six requirements are satisfied:
 the approach angle must be at least 25º;
the departure angle must be at least 25º;
 the ramp angle must be at least 25º;
 the ground clearance under the front axle must be at least 250 mm;
 the ground clearance between the axles must be at least 300 mm;
 the ground clearance under the rear axle must be at least 250 mm.
7.2.                                    Load and checking conditions.
7.2.1.                              NOT USED
7.2.2.                              Power-driven vehicles other than those referred to in paragraph 7.2.1. must be loaded to the technically permissible maximum mass stated by the manufacturer.
7.2.3.                              The ability to climb the required gradients (25 per cent and 30 per cent) is verified by simple calculation. In exceptional cases, however, the technical services may ask for a vehicle of the type concerned to be submitted to it for an actual test.
7.2.4.                              When measuring front and rear incidence angles and ramp angles, no account is taken of underrun protective devices.

7.3.                                    Definitions and sketches of front and rear incidence angles, ramp angle and ground clearance.
7.3.1.                              'Approach angle' - see Standard ISO 612:1978, term No. 6.10.
7.3.2.                              'Departure angle' - see Standard ISO 612:1978, term No. 6.11.
7.3.3.                              'Ramp angle' - see Standard ISO 612:1978, term No. 6.9.
7.3.4.                              "Ground clearance between the axles" means the shortest distance between the ground plane and the lowest fixed point of the vehicle. Multi-axle bogies are considered to be a single axle.
7.3.5.                              "Ground clearance beneath one axle" means the distance beneath the highest point of the arc of a circle passing through the centre of the tyre footprint of the wheels on one axle (the inner wheels in the case of twin tyres) and touching the lowest fixed point of the vehicle between the wheels. No rigid part of the vehicle may project into the shaded area of the diagram. Where appropriate, the ground clearance of several axles is indicated in accordance with their arrangement, for example 280/250/250.
7.4.                                    Combined designation.
Symbols M and N may be combined with symbol G.
For example, a vehicle of category N1 which is suited for off-road use may be designated as N1G.
