likely to invalidate the validation report shall be brought to the attention of the Type Approval Authority which may require a new validation process to be conducted.
              1.4. In the case of a RUPD where the cross-member does not have a vertical flat surface of at least 50 per cent of the minimum section height of the cross‑member according to paragraph 7.1. or 25.5. of this Regulation at the height of the points of application of the test forces according to paragraph 16.1. or 25.1., the manufacturer shall supply the Technical Service with a device that allows the application of horizontal test loads on the cross-member with the test equipment used by the Technical Service. The device shall not modify the dimensional and mechanical characteristics of the RUPD or increase its resistance during test. The device shall neither be rigidly fixed to the RUPD nor to the test equipment.

2. Test conditions for vehicles
2.1. The vehicle shall be at rest on a level, flat, rigid and smooth surface.
2.2. The front wheels shall be in the straight‑ahead position.
2.3. The tyres shall be inflated to the pressure recommended by the vehicle manufacturer.
2.4. The vehicle may, if necessary to achieve the test forces required in paragraph 3.1. below, be restrained by any method, this method to be specified by the vehicle manufacturer.
2.5. Vehicles equipped with hydropneumatic, hydraulic or pneumatic suspension or a device for automatic levelling according to load shall be tested with the suspension or device in the normal running condition specified by the manufacturer.
3. Test procedure
              3.1. The requirements of paragraphs 7.3. and 25.7. of this Regulation shall be verified by means of suitable test mandrels; the forces for tests prescribed in paragraphs 3.1.1. and 3.1.2. below shall be applied separately and consecutively, via a surface not more than 250 mm in height (but covering the maximum section height of the cross-member or RUP, the exact height shall be indicated by the manufacturer) and 200 mm wide, with a radius of curvature of 5 ± 1 mm at the vertical edges. The RUP shall offer adequate resistance to forces applied parallel to the longitudinal axis of the vehicle. The surface shall not be rigidly fixed to the RUPD or to the RUP and shall be articulated in all directions. The height above the ground of the centre of the surface shall be defined by the manufacturer within the lines that bound the device horizontally. When the test is carried out on a vehicle the height shall not, however, exceed the height as specified in paragraphs 16.1. and 16.2. or as specified in paragraphs 25.1. and 25.2. of this Regulation when the vehicle is unladen.
