that the absence of the components omitted has no effect on the results of the verification,
so far as the requirements of this Regulation are concerned.
23.4. The Competent Authority shall verify the existence of satisfactory arrangements for ensuring
effective checks on conformity of production before type approval is granted.

25. REQUIREMENTS FOR RUP
25.1. The ground clearance with respect to the underside of the RUP, even when the vehicle is
unladen, must not exceed 550mm over its entire width.
25.2. The RUP must be situated as close to the rear of the vehicle as possible.
25.3. The width of the RUP shall at no point exceed the width of the rear axle measured at the
outermost points of the wheels, excluding the bulging of the tyres close to the ground, nor
shall RUP be more than 100mm shorter on either side. Where the device is contained in or
comprises the vehicle bodywork which itself extends beyond the width of the rear axle, the
requirement, that the width of the RUP shall not exceed that of the rear axle, shall not apply.
However, in case of vehicles of Categories O and O where the tyres project for more than
half of their width outside the bodywork (excluding the wheel guards) or outside the chassis
in the absence of bodywork, the width of the RUP shall not be less than 100mm deducted
from the distance measured between the innermost points of the tyres, excluding the
bulging of the tyres close to the ground, on either side. Where there is more than one rear
axle, the width to be considered is that of the widest rear axle. In addition, the requirements
of Paragraphs 3.1.2. and 3.1.3. of Annex 5 relating the distance of the points of application
of the test forces from the outer edges of the rear wheels (Annex 1, Item 7) shall be verified
and recorded in the type approval communication form.
25.4. The section height of the RUP must not be less than 100mm. The lateral extremities of the
RUP must not bend to the rear or have a sharp outer edge, this condition is fulfilled when
the lateral extremities of the RUP are rounded on the outside and have a radius of curvature
of not less than 2.5mm.
25.5. The RUP may be so designed to have several positions at the rear of the vehicle. In this
event, there must be a guaranteed method of securing it in the service position so that any
unintentional change of position is precluded. The force applied by the operator to vary the
position of the RUP must not exceed 40 daN.
25.6. The RUP must offer adequate resistance to forces applied parallel to the longitudinal axis of
the vehicle and be connected, when in the service position, with the chassis side-members
or whatever replaces them. This requirement will be satisfied if it is shown that both during
and after the application of the forces described in Annex 5 the horizontal distance between
the rear of the RUP and the rear extremity of the vehicle, including any platform lift
mechanism, does not exceed 400mm at any of the points where the test forces are applied.
In measuring this distance, any part of the vehicle which is more than 2 m above the ground
when the vehicle is unladen must be excluded.
25.7. A practical test shall not be required where it can be shown by calculation that the
requirements of Annex 5, Paragraph 3, are met. Where a practical test is carried out, the
device must be connected to the chassis side-members of the vehicle or to a significant part
of these or to other structural members.

29. PRODUCTION DEFINITELY DISCONTINUED

minimum distance apart of 700mm and a maximum of 1 m. The exact location of the points of
application shall be specified by the manufacturer.
3.1.2. In the cases defined in Paragraphs 1.1.1 and 1.1.2 of this Annex a horizontal force of 50kN or
25% of the force generated by the maximum mass of the vehicle, whichever is the lesser, shall
be applied consecutively to two points located 300 ± 25mm 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.
3.1.3. In the cases defined in Paragraph 1.1.3 of this Annex a horizontal force of 50kN or 25% of the
force generated by the maximum mass of the vehicle for which the device is intended,
whichever is the lesser, shall be applied consecutively to two points located at the discretion of
the manufacturer of the rear underrun protective device and to a third point located on the line
joining these two points, in the median vertical plane of the device.
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 Paragraphs 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 horizontal centerline and within 50mm of
each vertical edge closest to the intended points of force application, as defined in that
paragraph, and
3.2.2. For the requirement under Paragraph 3.1.2, at the intersection of the horizontal and vertical
centerlines of each element furthest from the vertical centerline of the device or of the vehicle,
whichever is applicable. These points should be a maximum of 325mm from the longitudinal
planes tangential to the outer edges of the wheels on the rear axle.
