5 Test Methods
5.1 Test conditions
5.1.1 The test shall be carried out on the same vehicle using the same towing device; the vehicle under test shall be in the kerb mass state, and fixed on a horizontal surface. 5.1.2 It is allowed to be carried out on a body or chassis that is completely equivalent to the actual vehicle; The fixing method shall ensure not influence the strength of the towing device; the force condition of the towing device shall be consistent with the entire vehicle.
5.2 Static load test
5.2.1 Separately apply the static load F of the horizontal tension and horizontal compression to the towing device; the direction of static load F is parallel to the longitudinal centerline of the vehicle.
5.2.2 The horizontal line penetrating the working area center point of the towing device, and paralleling to the longitudinal vertical surface of the vehicle shall separately exert the tension and compression static load F (see Figure 2) to the towing device along the vertical direction ??5??, and the horizontal direction ??25??. Select any angle to perform the tension and compression tests.
