The requirements of paragraph 5.4 shall not apply.
6.7.2.
The wheels, wheel nuts, hub caps and wheel discs shall not exhibit any pointed or sharp projections that extend beyond the external plane of the wheel rim. Wing nuts shall not be allowed.
6.7.3.
When the vehicle is travelling in a straight line, no part of the wheels other than the tyres, situated above the horizontal plane passing through their axis of rotation shall project beyond the vertical projection, in a horizontal plane of the external surface or structure. However, if functional requirements so warrant, wheel discs which cover wheel and hub nuts may project beyond the vertical projection of the external surface or structure on condition that the radius of curvature of the surface of the projecting part is not less than 30 mm and that the projection beyond the vertical projection of the external surface or structure in no case exceeds 30 mm.
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 100 mm.
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 2,5 mm 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 1 mm 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 10 mm 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 10 mm beyond the vertical projection of the floor line, so long as it terminates in rounded edges, the minimum radius of curvature being 2,5 mm.
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 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.
6.14. Windows.
6.14.1.
Windows which move outwards from the external surface of the vehicle shall comply with the following provisions in all positions of use:
6.14.1.1.
no exposed edge shall face forwards;
6.14.1.2.
