       1. DEFINITIONS

        For the purpose of this Regulation

       1.1. "Lens" means the outermost component of the headlamp (unit) which transmits light through the illuminating surface;

       1.2. "Coating" means any product or products applied in one or more layers to the outer face of a lens;

       1.3. Headlamps of different "types" are headlamps which differ in such essential respects as:

       1.3.1. The trade name or mark;

       1.3.2. The characteristics of the optical system;

       1.3.3. The inclusion of additional components capable of altering the optical effects by reflection, refraction or absorption; and/or deformation during operation;

       1.3.4. Suitability for right-hand or left-hand traffic or for both traffic systems;

       1.3.5. Ability to provide a passing-beam or a driving-beam or both;

       1.3.6. The materials constituting the lenses and coating, if any.

       1.3.7. The holder intended to accommodate the filament lamp (or lamps) of one of the following categories: R2 and/or HS1;[2/]

       2. APPLICATIONS FOR APPROVAL [1/]

       2.1. The application for approval shall be submitted by the owner of the trade name or mark or by his duly accredited representative.  It shall specify:

        Whether the headlamp is intended to provide both a passing beam and a driving beam   or only one of these beams;

        Whether, if the headlamp is intended to provide a passing beam, it is designed for both left-hand and right-hand traffic or for either left-hand or right-hand traffic only.

        If the headlamp is equipped with an adjustable reflector, the mounting position(s) of the headlamp in relation to the ground and the longitudinal median plane of the vehicle.

       2.2. The application shall be accompanied, in respect of each type of headlamp, by:

       2.2.1. 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;

       If the headlamp is equipped with an adjustable reflector, an indication of the mounting position(s) of the headlamp in relation to the ground and the longitudinal median plane of the vehicle, if the headlamp is for use in that (those) position(s) only.

       2.2.2. A brief technical specification;

       2.2.3. Two samples of the type of headlamp;

       2.2.4. For the test of plastic material of which the lenses are made;

       2.2.4.1. Thirteen lenses.

       2.2.4.1.1. 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.

       2.2.4.1.2. Every such lens or sample of material shall be produced
