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. below.
6.3.  Grilles and gaps
6.3.1.  The requirements of paragraph 5.4. above 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 40 mm and provided that the grilles and gaps have a functional purpose.  For gaps of between 40 mm and 25 mm the radii of curvature shall be 1 mm or more.  However, if the distance between two consecutive elements is equal to or less than 25 mm, the radii of curvature of external faces of the elements shall not be less than 0.5 mm.  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.
6.4.  Windscreen wipers
6.4.1.  The windscreen wiper fittings shall be such that the wiper shaft is furnished with a protective casing which has a radius of curvature meeting the requirements of paragraph 5.4. above and an end surface area of not less than 150 mm2.  In the case of rounded covers, these shall have a minimum projected area of 150 mm2 when measured not more than 6.5 mm from the point projecting furthest.  These requirements shall also be met by rear window wipers and headlamp wipers.
6.4.2.  Paragraph 5.4. shall not apply to the wiper blades or to any supporting members.  However, these units shall be so made as to have no sharp angles or pointed or cutting parts.
6.5.   Bumpers
6.5.1.  The ends of the bumpers shall be turned in towards the external surface in order to minimize the risk of fouling.  This requirement is considered to be satisfied if either the bumper is recessed or integrated within the bodywork or the end of the bumper is turned in so that it is not contactable by a 100 mm sphere and the gap between the bumper end and the surrounding bodywork does not exceed 20 mm.
6.5.2. If the line of the bumper which corresponds to the outline contour of the car vertical projection is on a rigid surface, that surface shall have a minimum radius of curvature of 5 mm at all its points lying from the contour line to 20 mm inward, and a minimum radius of curvature of 2.5 mm in all other cases.  This provision applies to that part of the zone
