6. PARTICULAR SPECIFICATIONS
6.1. Ornaments
6.1.1. Added ornaments which project more than 10mm from their support shall retract, become
detached or bend over under a force of 10daN exerted at their most salient point in any
direction in a plane approximately parallel to the surface of which they are mounted. These
provisions shall not apply to ornaments on radiator grilles, to which only the general
requirements of Paragraph 5. shall apply.
To apply the 10daN force a flat-ended ram of not more than 50mm diameter shall be used.
Where this is not possible, an equivalent method shall be used. After the ornaments are
retracted, detached or bent over, the remaining projections shall not project more than
10mm. These projections shall in any case satisfy the provisions of Paragraph 5.2. If the
ornament is mounted on a base, this base is regarded as belonging to the ornament and not
to the supporting surface.
6.1.2. Protective strips or shielding on the external surface shall not be subject to the requirements
of Paragraph 6.1.1. above: however, they shall be firmly secured to the vehicle.
6.2. Headlights
6.2.1. Projecting visors and rims shall be permitted on headlights, provided that their projections,
as measured in relation to the external transparent surface of the headlight does not exceed
30mm and their radius of curvature is at least 2.5mm throughout. In the case of a headlamp
mounted behind an additional transparent surface, the projection shall be measured from
the outermost transparent surface. The projections shall be determined according to the
method described in Paragraph 3. of Annex 3 to this Regulation.
6.2.2. Retracting headlights shall meet the provisions of Paragraph 6.2.1. above in both the
operative and retracted positions.
6.2.3. The provisions of Paragraph 6.2.1. above do not apply to headlamps which are sunk into
the bodywork or which are "overhung" by the bodywork, if the latter complies with the
requirements of Paragraph 6.9.1.
6.3. Grilles and Gaps
6.3.1. The requirements of Paragraph 5.4. shall not apply to gaps between fixed or movable
elements, including those forming part of air intake or outlet grilles and radiator grilles,
provided that the distance between consecutive elements does not exceed 40mm and
provided that the grilles and gaps have a functional purpose. For gaps of between 40mm
and 25mm the radii of curvature shall be of 1mm or more. However, if the distance between
two consecutive elements is equal to or less than 25mm, the radii of curvature of external
faces of the elements shall not be less than 0.5mm. The distance between two consecutive
elements of grilles and gaps shall be determined according to the method described in
Paragraph 4 of Annex 3 to this Regulation.
6.3.2. The junction of the front with the side faces of each element forming a grille or gap shall be
blunted.

Figure 1
6.5.3. The requirement of Paragraph 6.5.2. shall not apply to parts on or of the bumper or to
bumper insets which have a projection of less than 5mm, with special reference to joint
covers and jets for headlamp washers; but the outward facing angles of such parts shall be
blunted, save where such parts protrude less than 1.5mm.
6.5.4. The requirement of Paragraph 6.5.2. above does not apply to the bumper cover. The
provisions of Paragraph 5. of this Regulation remain applicable.

6.8. Sheet-metal Edges
6.8.1. Sheet-metal edges, such as gutter edges and the rails of sliding doors, shall not be
permitted unless they are folded back or are fitted with a shield meeting the requirements of
this Regulation which are applicable to it.
An unprotected edge shall be considered to be folded back either if it is folded back by
approximately 180°, or if it is folded towards the bodywork in such a manner that it cannot
be contacted by a sphere having a diameter of 100mm.
The requirements of Paragraph 5.4. shall not apply to the following sheet metal edges: rear
edge of bonnet and front edge of rear luggage boot.
6.9. Body Panels
6.9.1. Folds in body panels may have a radius of curvature of less than 2.5mm, provided that it is
not less than one-tenth of the height "H" of the projection, measured in accordance with the
method described in Paragraph 1. of Annex 3.
6.10. Lateral Air or Rain Deflectors
6.10.1. Lateral deflectors shall have a radius of curvature of at least 1mm on edges capable of
being directed outwards.
6.11. Jacking Brackets and Exhaust Pipes
6.11.1. The jacking brackets and exhaust pipe(s) shall not project more than 10mm beyond the
vertical projection of the floor line lying vertically above them. As an exception to this
requirement an exhaust pipe may project more than 10mm beyond the vertical projection of
the floor line, so long as it terminates in rounded edges, the minimum radius of curvature
being 2.5mm.
6.12. Air Intake and Outlet Flaps
6.12.1. Air intake and outlet flaps shall meet the requirements of Paragraphs 5.2., 5.3. and 5.4.
above in all positions of use.
6.13. Roof
6.13.1. Opening roofs shall be considered only in the closed position.
6.13.2. Convertible vehicles shall be examined with the hood in both the raised and lowered
positions.
6.13.2.1. With the hood lowered, no examination shall be made of the vehicle inside an imaginary
surface formed by the hood when in the raised position.
6.13.2.2. Where a cover for the linkage of the hood when folded is provided as standard equipment,
the examination shall be made with the cover in position.

6.17.4. The bases of aerials shall not project more than 40mm when determined according to the
procedure of Annex 3, Paragraph 2.
6.17.4.1. In cases where by the absence of a flexible shaft or part it is not possible to identify what the
base is of an aerial this requirement is deemed to be met if, after a horizontal force of not
more than 50daN in forward and rearward direction is applied by a flat-ended ram of not
more than 50mm diameter at the most salient part of the aerial:
(a)
(b)
The aerial bends towards the support and does not project more than 40mm, or
The aerial breaks off and the remaining part of the aerial does not show any sharp or
dangerous part that can be contacted by the 100mm sphere and does not project
more than 40mm.
6.17.4.2. Paragraphs 6.17.4. and 6.17.4.1. shall not apply to aerials located behind the vertical
transversal plane passing through the "R" point of the driver, provided that the maximum
projection of the aerial including its housing does not exceed 70mm when determined
according to the procedure of Paragraph 2. of Annex 3 to this Regulation.
If the aerial is located behind that vertical plane but projects more than 70mm,
Paragraph 6.17.4.1. above shall apply using a projection limit of 70mm instead of 40mm.
6.18. Assembly Instructions
6.18.1. Luggage racks, ski racks and radio receiving or transmitting aerials that have been
approved as separate technical units may not be offered for sale, sold or purchased unless
accompanied by assembly instructions. The assembly instructions shall contain sufficient
information to enable the approved components to be mounted on the vehicle in a manner
that complies with the relevant provisions of Paragraphs 5. and 6 of this Regulation. In
particular, the positions of use must be indicated for telescopic aerials.
7. MODIFICATION OF A VEHICLE TYPE
7.1. Every modification to an existing vehicle type shall be notified to the Type Approval
Authority which approved the vehicle type. The Type Approval Authority shall then either:
(a)
(b)
Decide, in consultation with the manufacturer, that a new type approval is to be
granted, or
Apply the procedure contained in Paragraph 7.1.1. (Revision) and, if applicable, the
procedure contained in Paragraph 7.1.2. (Extension).
7.1.1. Revision
When particulars recorded in the information folder have changed and the Type Approval
Authority considers that the modifications made are unlikely to have an appreciable adverse
effect and that in any case the vehicle still complies with the requirements, the modification
shall be designated a "revision".
In such a case, the Type Approval Authority shall issue the revised pages of the information
folder as necessary, marking each revised page to show clearly the nature of the
modification and the date of re-issue. A consolidated updated version of the information
folder, accompanied by a detailed description of the modification, shall be deemed to meet
this requirement.

8.4. The Type Approval Authority which has granted type approval may at any time verify the
conformity control methods applicable to each production unit.
8.4.1. In every inspection, the test books and production survey records shall be presented to the
visiting inspector.
8.4.2. The inspector may take samples at random to be tested in the manufacturer's laboratory.
The minimum number of samples may be determined according to the results of the
manufacturer's own verification.
8.4.3. When the quality level appears unsatisfactory or when it seems necessary to verify the
validity of the tests carried out in the application of Paragraph 8.4.2. above, the inspector
shall select samples to be sent to the technical service which has conducted the type
approval tests.
8.4.4. The Type Approval Authority may carry out any test prescribed in this Regulation.
8.4.5. The normal frequency of inspections authorized by the Type Approval Authority shall be one
per two years. In the case where negative results are recorded during one of these visits,
the Type Approval Authority shall ensure that all necessary steps are taken to re-establish
the conformity of production as rapidly as possible.
9. PENALTIES FOR NON-CONFORMITY OF PRODUCTION
9.1. The approval granted in respect of a vehicle type pursuant to this Regulation may be
withdrawn if the requirement laid down in Paragraph 8.1. above is not complied with.
9.2. If a Party to the Agreement applying this Regulation withdraws an approval it has previously
granted, it shall forthwith notify the other Contracting Parties applying this Regulation by
means of a communication form conforming to the model in Annex 1 to this Regulation.
10. PRODUCTION DEFINITELY DISCONTINUED
If the holder of the approval completely ceases to manufacture the type approved in
accordance with this Regulation, he shall so inform the Type Approval Authority which
granted the approval. Upon receiving the relevant communication that authority shall inform
thereof the other Parties to the 1958 Agreement which apply this Regulation by means of a
communication form conforming to the model in Annex 1 to this Regulation.
11. NAMES AND ADDRESSES OF TECHNICAL SERVICES CONDUCTING APPROVAL
TESTS, AND OF TYPE APPROVAL AUTHORITIES
The Parties to the Agreement applying this Regulation shall communicate to the United
