4. APPLICATION FOR APPROVAL
4.1. The application for approval of a vehicle type with regard to its lateral protection shall be
submitted by the vehicle manufacturer or by his duly accredited representative.
4.2. It shall be accompanied by the undermentioned documents in triplicate and by the following
particulars:
4.2.1. a detailed description of the vehicle type with respect to its structure, dimensions, lines and
constituent materials in so far as required for the purpose of this Regulation;
4.2.2. drawings of the vehicle showing the vehicle type in side and rear elevation and design
details of the lateral parts of the structure;
4.2.3. a detailed description of the specific device for lateral protection: its dimensions, lines,
constituent materials and position on the vehicle.
4.3. A vehicle representative of the type to be approved shall be submitted to the technical
service responsible for controlling the technical specifications.
4.3.1. A vehicle not comprising all the components proper to the type may be accepted for
approval provided that it can be shown that the absence of the components omitted has no
detrimental effect on the results of the approval so far as the requirements of this Regulation
are concerned.
4.3.2. It shall be the responsibility of the applicant for approval to show that acceptance of the
variants referred to in Paragraph 4.3.1. above is compatible with compliance with the
requirements of this Regulation.
4.3.3. The competent authority shall verify the existence of satisfactory arrangements for ensuring
effective control of production before type-approval is granted.
5. APPROVAL
5.1. If the vehicle submitted for approval pursuant to this Regulation meets the requirements of
Paragraphs 6 and 7 below, approval of that vehicle type shall be granted.
5.2. An approval number shall be assigned to each type-approved. Its first two digits (at
present 00 for the Regulation in its original form) shall indicate the series of amendments
incorporating the most recent major technical amendments made to the Regulation at the
time of issue of the approval. The same Contracting Party may not assign the same
number to another vehicle type.
5.3. Notice of approval or refusal or extension of approval of a vehicle type pursuant to this
Regulation shall be communicated to the Parties to the Agreement which apply this
Regulation, by means of a form conforming to the model in Annex 1 to this Regulation.

6.2. Positioning of the Vehicle During Checks
When checked for compliance with the technical specifications set out in Paragraph 7
below, the position of the vehicle shall be as follows:
The vehicle shall be positioned on a horizontal and flat surface;
The steered wheels shall be in a straight-ahead position;
The vehicle shall be unladen;
Semi-trailers shall be positioned on their supports in an essentially horizontal manner.
7. TECHNICAL SPECIFICATIONS FOR LATERAL PROTECTIVE DEVICES
7.1. The lateral protective device shall not increase the overall width of the vehicle and the main
part of its outer surface shall not be more than 120 mm inboard from the outermost plane
(maximum width) of the vehicle. Its forward end may be turned inwards on some vehicles in
accordance with Paragraphs 7.4.3 and 7.4.4. Its rearward end shall not be more than
30 mm inboard from the outermost edge of the rear tyres (excluding any bulging of the tyres
close to the ground) over at least the rearmost 250 mm.
7.2. The outer surface of the device shall be smooth, and so far as possible continuous from
front to rear; adjacent parts may however overlap provided that the overlapping edge faces
rearwards or downwards, or a gap of not more than 25 mm measured longitudinally may be
left, provided that the rearward part does not protrude outboard of the forward part; domed
heads of bolts or rivets may protrude beyond the surface to a distance not exceeding 10 mm
and other parts may protrude to the same extent provided that they are smooth and similarly
rounded; all external edges and corners shall be rounded with a radius not less than
2.5 mm.
7.3. The device may consist of a continuous flat surface, or of one or more horizontal rails, or a
combination of surface and rails; when rails are used they shall be not more than 300 mm
apart and not less than:
50 mm high in the case of N and O ;
100 mm high and essentially flat in the case of N and O ;
combinations of surfaces and rails shall form a practically continuous sideguard subject,
however, to the provisions of 7.2.
7.4. The forward edge of the sideguard shall be constructed as follows:
7.4.1. Its position shall be:
7.4.1.1. on a motor vehicle: not more than 300 mm to the rear of the vertical plane perpendicular to
the longitudinal plane of the vehicle and tangential to the outer surface of the tyre on the
wheel immediately forward of the guard;
7.4.1.2. on a drawbar trailer: not more than 500 mm to the rear of the plane defined in
Paragraph 7.4.1.1;

7.8. Sideguards shall be essentially rigid, securely mounted (they shall not be liable to loosening
due to vibration in normal use of the vehicle) and, except as regards the parts listed in
Paragraph 7.9, made of metal or any other suitable material. The sideguard shall be
considered suitable if it is capable of withstanding a horizontal static force of 1 kN applied
perpendicularly to any part of its external surface by the centre of a ram the face of which is
circular and flat, with a diameter of 220 mm ± 10 mm, and if the deflection of the guard
under load is then not more than:
30 mm over the rearmost 250 mm of the guard, and
150 mm over the remainder of the guard.
Compliance with this requirement can be verified by calculation.
7.9. Components permanently fixed to the vehicle, e.g. spare wheels, batterybox, air tanks, fuel
tanks, lamps, reflectors and tool boxes may be incorporated in the sideguard, provided that
they meet the dimensional requirements of this Regulation. The requirements of
Paragraph 7.2. shall generally apply as regards gaps between protective devices and
permanently fixed components.
7.10. The guard may not be used for the attachment of brake, air or hydraulic pipes.
8. DEROGATIONS
8.1. By derogation from the above provisions, vehicles of the following types need comply only
as indicated in each case:
8.1.1. An extendible trailer shall comply with all the requirements of Paragraph 7 when closed to
its minimum length; when the trailer is extended, however, the sideguards shall comply with
Paragraphs 7.6, 7.7, and 7.8, and with either 7.4 or 7.5, but not necessarily both; extension
of the trailer shall not produce gaps in the length of the sideguards;
8.1.2. A tank-vehicle, that is a vehicle designed solely for the carriage of a fluid substance in a
closed tank permanently fitted to the vehicle and provided with hose or pipe connections for
loading or unloading, shall be fitted with sideguards which comply so far as is practicable
with all the requirements of Paragraph 7; strict compliance may be waived only where
operational requirements make this necessary;
8.1.3. On a vehicle fitted with extendible legs to provide additional stability during loading,
unloading or other operations for which the vehicle is designed, the sideguard may be
arranged with additional gaps where these are necessary to permit extension of the legs.
8.1.4. On a vehicle equipped with anchorage points for ro-ro transport, gaps shall be permitted
within the sideguard to accept the passage and tension of fixing ropes.
8.2. If the sides of the vehicle are so designed and/or equipped that by their shape and
characteristics the component parts together meet the requirements of Paragraph 7, they
may be regarded as replacing the sideguards.

13. NAMES AND ADDRESSES OF TECHNICAL SERVICES RESPONSIBLE FOR
CONDUCTING APPROVAL TESTS, AND OF ADMINISTRATIVE DEPARTMENTS
The Parties to the Agreement which apply this Regulation shall communicate to the United
Nations Secretariat the names and addresses of the technical services responsible for
conducting approval tests and of the administrative departments which grant approval and
to which forms certifying approval or extension or refusal or withdrawal of approval, issued
in other countries, are to be sent.
