ANNEX III TEST PROCEDURES

B — Test method II

1. IMPACT AND CRUSHING TESTS

1.1. Impact at the rear

1.1.1. The tractor shall be so placed in relation to the weight that the weight will strike the roll-over protection structure when the impact face of the weight and the supporting chains or wire ropes are at an angle of 20 ° to the vertical unless the roll-over protection structure at the point of contact has, during deflection, a greater angle to the vertical. In this case the impact face of the weight shall be adjusted by means of an additional support so that it is parallel to the roll-over protection structure at the point of impact at the moment of maximum deflection, the supporting chains or wire ropes remaining at an angle of 20 ° to the vertical. Steps must be taken to reduce the tendency of the weight to turn about the point of contact. The suspended height of the weight shall be so adjusted that the locus of its centre of gravity passes through the point of contact.

1.1.2. Tractors with rigid bodies shall be lashed down. The points of attachment of the lashings shall be approximately 2 m behind the rear axle and 1,5 m in front of the front axle. They shall either be in the plane in which the centre of gravity of the pendulum will swing or more than one lashing shall give a resultant force in this plane, as in Annex IV, fig. 5.

1.2. Impact at the front

1.2.1. The tractor shall be so placed in relation to the weight that the weight will strike the roll-over protection structure when the impact face of the weight and the supporting chains or wire ropes are at an angle of 20 ° to the vertical unless the roll-over protection structure at the point of contact has, during deflection, a greater angle to the vertical. In this case the impact face of the weight shall be adjusted by means of an additional support so that it is parallel to the roll-over protection structure at the point of impact at the moment of maximum deflection, the supporting chains or wire ropes remaining at an angle of 20 ° to the vertical.

1.3. Impact at the side

1.3.1. The tractor shall be so placed in relation to the weight that the weight will strike the roll-over protection structure when the impact face of the weight and the supporting chains or wire ropes are vertical unless the protection structure at the point of contact is, during deflection, other than vertical. In this case the impact face of the weight shall be adjusted by means of an additional support so that it is parallel to the protection structure at the point of impact at the moment of maximum deflection, the supporting chains or wire ropes remaining vertical. The suspended height of the weight shall be so adjusted that the locus of its centre of gravity passes through the point of contact.
