less than 100 mm for category N2 vehicles and 120 mm for vehicles of category N3.
10.4.                                The device may be so designed that its position at the front of the vehicle can be varied.  In this event, there shall be a guaranteed method of securing it in the service position so that any unintentional change of position is precluded.  It shall be possible for the operator to vary the position of the device by applying a force not exceeding 40 daN;
10.5.                                The FUP shall have sufficient strength that the horizontal distance measured in the rearward direction between the foremost part of the vehicle after the application of the test forces (specified in this annex) and the test ram contact surface on the vehicle does not exceed 400 mm.
10.6.                                In measuring these distances, any part of the vehicle, which is more than 2 m above the ground shall be excluded.
10.7.                                The maximum ground clearance with respect to the underside of the  FUP shall be no more than 400 mm, as specified in paragraph 2 of annex 5, between the two points P1. Outboard of each point P1 this height may be greater than 400 mm providing the underside is not above a plane passing through the underside of the FUP directly below the point P1 and forming a slope at 15º above the horizontal (see figure 3).
10.8.                                The maximum ground clearance with respect to the underside of the FUP between the two points P1 shall be no more than 450 mm taking into account their movement during the application of the test load.
10.9.                                The width of the FUP shall at no point exceed the width of the mudguards covering the wheels of the foremost axle nor shall it be more than 100 mm shorter on either side than the foremost axle measured at the outermost points of the tyres, excluding the bulging of the tyres close to the ground (see figure 1), or 200 mm shorter on either side, measured from the outermost points of the access steps to the driver's cabin.
