Regulation No. 57

UNIFORM PROVISIONS CONCERNING THE APPROVAL OF HEADLAMPS FOR MOTOR CYCLES AND VEHICLES TREATED AS SUCH

       1. SCOPE

This Regulation applies to the approval of headlamps using filament lamps and incorporating lenses of glass or plastic material [*/, which are provided for the equipment of motor cycles and vehicles treated as such.]
2.                                          DEFINITIONS
         For the purpose of this Regulation,
2.1.                                    "Lens" means the outermost component of the headlamp (unit) which transmits light through the illuminating surface;
2.2.                                    "Coating" means any product or products applied in one or more layers to the outer face of a lens;
2.3.                                    Headlamps different "types" are headlamps which differ in such essential respects as:
2.3.1.                              the trade name or mark;
2.3.2.                              marking of the headlamp as defined in paragraph 4.1.4 below;
2.3.3.                              the characteristics of the optical system;
2.3.4.                              the inclusion or the suppression of components capable of altering the optical effects by reflection, refraction or absorption and/or deformation during operation. A change in the colour of the beams emitted by headlamps whose other characteristics are not changed does not constitute a change of headlamp type. The same approval number shall accordingly be assigned to such headlamps.
2.3.5.                              the materials constituting the lenses and coating, if any.
3.                                          APPLICATION FOR APPROVAL OF A HEADLAMP [1/]
3.1.                                    The application for approval shall be submitted by the owner of the trade name or mark or by his duly accredited representative.
3.2.                                    Every application for approval shall be accompanied by:
3.2.1.                              drawings in triplicate in sufficient detail to permit identification of the type and representing a frontal view of the headlamp, with details of lens ribbing if any, and the cross-section; the drawings shall indicate the space reserved for the approval mark;
3.2.2.                              a brief technical description stating, in particular, the category or categories of the filament lamp provided (see annex 3, paragraph 6, to this Regulation);
3.2.3.                              two samples of the type of headlamp with colourless lenses. [2/]
3.2.4.                              for the test of plastic material of which the lenses are made:
3.2.4.1.                        thirteen lenses;
       3.2.4.1.1 six of these lenses may be replaced by six samples of material at least 60 x 80 mm in size, having a flat or convex outer surface and a substantially flat area (radius of curvature not less than 300 mm) in the middle measuring at least 15 x 15 mm;

       3.2.4.1.2 every such lens or sample of material shall be produced by the method to be used in mass production;

3.2.4.2.                                      a reflector to which the lenses can be fitted in accordance with the manufacturer's instructions.
3.3.                                    The materials making up the lenses and coatings, if any, shall be accompanied by the
