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. The order in which the forces are applied may be specified by the manufacturer.

              The device used to distribute the test force over the stated flat surface shall be connected to the force actuator through a swivel joint. The arrangement of the force actuator, whether pulling or pushing, shall be arranged such that it does not add any stiffness or stability to the underrun protection system structure, i.e. it shall neither increase the instability threshold force nor decrease the maximum deflection of the underrun protection system.

3.1.1. A horizontal force of 180 kN or 85 per cent of the force generated by the maximum mass of the vehicle, whichever is the lesser, shall be applied consecutively to two points situated symmetrically about the centre line of the device or of the vehicle whichever is applicable at a minimum distance apart of 700 mm and a maximum of 1 m. The exact location of the points of application shall be specified by the manufacturer.
Notwithstanding the provision above for non-separate cab vehicles of category N2 with a maximum mass not exceeding 8 t, the horizontal forces may be reduced to 100 kN or 50 per cent.
3.1.2. In the cases defined in paragraphs 1.1.1. and 1.1.2. of this annex a horizontal force of 100 kN or 50 per cent of the force generated by the maximum mass of the vehicle, whichever is the lesser, shall be applied consecutively to two points located 300 ± 25 mm from the longitudinal planes tangential to the outer edges of the wheels on the rear axle or of the RUPD, if it exceeds the width of the rear axle, and to a third point located on the line joining these two points, in the median vertical plane of the vehicle.
Notwithstanding the provision above for non-separate cab vehicles of category N2 with a maximum mass not exceeding 8 t, the horizontal forces may be reduced to 50 kN or 25 per cent.
3.1.3. Upon request of the manufacturer, the force levels can be reduced to 80 per cent of the requirement given in paragraphs 3.1.1. to 3.1.2. for the vehicles listed in Annex 6.
3.2. Replacement force application points
 If any point defined under paragraph 3.1. is located within the interruption area of the underrun protection device as mentioned in paragraph 7.4. or 25.8. of this Regulation, the test forces shall be applied at replacement points located:
3.2.1. for the requirement under paragraph 3.1.1., on the
