ADMINISTRATIVE PROVISIONS SCOPE 1/ This Regulation applies to motor vehicle headlamps which may incorporate lenses of glass or plastic material. 1. DEFINITIONS For the purpose of t
22、his Regulation, 1.1. “Lens“ means the outermost component of the headlamp (unit) which transmits light through the illuminating surface; 1.2. “Coatinq“ 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 dif
23、fer 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 or elimination of components capable of altering the optical effects by reflection, refraction, absorption and/or deformation during operation. However, the fittin
24、g or elimination of filters intended solely to change the colour of the beam but not its light distribution does not entail a change of type; 1.3.4. suitability for right-hand or left-hand traffic or for both traffic systems; 1.3.5. the kind of beam produced (passing beam, driving beam or both); 1.3
25、.6. the materials constituting the lenses and coating, if any. 1/ Nothing in this Regulation shall prevent a Party to the Agreement applying this Regulation from prohibiting the combination of a headlamp incorporating a lens of plastic material approved under this Regulation with a mechanical headla
26、mp-cleaning device (with wipers). E/ECE/324 E/ECE/TRANS/505 Rev.1/Add.19/Rev.3 Regulation No. 20 page 6 2. APPLICATION FOR APPROVAL OF A HEADLAMP 2/ 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:
27、 2.1.1. whether the headlamp is intended to provide both a passing beam and a driving beam or only one of these beams; 2.1.2. 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; 2
28、.1.3. 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. Every application for approval shall be accompanied by: 2.2.1. drawings in triplicate in sufficient detail to perm
29、it 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; 2.2.1.1. if the headlamp is equipped with an adjustable reflector, an indication of the mou
30、nting 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 description; 2.2.3. two samples of the type of headlamp; 2.2.3.1. for the testing of a coloured filter o
31、r coloured screen (or of a coloured lens): two samples. 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 s
32、ubstantially flat area (radius of curvature not less than 300 mm) in the middle measuring at least 15 x 15 mm; 2/ Application for approval of a filament lamp: see Regulation No. 37. E/ECE/324 E/ECE/TRANS/505Rev.1/Add.19/Rev.3 Regulation No. 20 page 7 2.2.4.1.2. every such lens or sample of material
33、shall be produced by the method to be used in mass production; 2.2.4.2. a reflector to which the lenses can be fitted in accordance with the manufacturers instructions. 2.3. The materials making up the lenses and coatings, if any, shall be accompanied by the test report of the characteristics of the
34、se materials and coatings if they have already been tested. 2.4. The Competent Authority shall verify the existence of satisfactory arrangements for ensuring effective control on conformity of production before type approval is granted. 3. MARKINGS 3/ 3.1. Headlamps submitted for approval shall bear
35、 the trade name or mark of the applicant. 3.2. They shall comprise, on the lens and on the main body, 4/ spaces of sufficient size for the approval mark and the additional symbols referred to in paragraph 4.; these spaces shall be indicated on the drawings referred to in paragraph 2.2.1. above. 3.3.
36、 Headlamps designed to satisfy the requirements both of right-hand and of left-hand traffic shall bear markings indicating the two settings of the optical unit on the vehicle or of the filament lamp on the reflector; these markings shall consist of the letters “R/D“ for the position for right-hand t
37、raffic and the letters “L/G“ for the position for left-hand traffic. 4. APPROVAL 4.1. General4.1.1. If all the samples of a type of headlamp submitted pursuant to paragraph 2 above satisfy the provisions of this Regulation, approval shall be granted. 3/ In the case of headlamps designed to meet the
38、requirements of traffic moving on one side of the road only (either right or left), it is further recommended that the area which can be occulted to prevent discomfort to users in a country where traffic moves on the side of the road opposite to that of the country for which the headlamp was designe
39、d should be outlined indelibly on the front lens. This marking is not necessary, however, where the area is clearly apparent from the design. 4/ If the lens cannot be detached from the main body of the headlamp, a space on the lens shall be sufficient. E/ECE/324 E/ECE/TRANS/505 Rev.1/Add.19/Rev.3 Re

Its first two digits (at present 02) shall indicate the series of amendments incorporating the most recent major technical amendments made to the Regulation at the time of issue of the approval. The same Contracting
42、Party may not assign the same number to another type of headlamp covered by this Regulation, except if the approval is extended to a device which only differs from the already approved device by the colour of the light emitted. 4.1.4.
