This standard follows the presentation and, to a large extent, the technical content of the corresponding international standard ISO 6742-1, Cycles Light
9、ing and retro-reflective devices Photometric and physical requirements Part 1: Lighting equipment, published by the International Organization for Standardization (ISO). The differences are as follows. a) Luminous intensity of the headlamp. The luminous intensity requirements of ISO 6742-1 have been
10、 adopted, but additional test points have been specified above the horizontal plane in compliance with the marker light requirements of the Department of Transport. b) Colour of light from headlamp. The selective yellow light, permitted by ISO 6742-1 as an alternative to a white light, has not been
11、included. c) Luminous intensity of the rear lamp. Higher luminous intensity requirements than those given in ISO 6742-1 have been specified over the whole range of test points, and additional test points at 5 from the vertical and horizontal planes have been included. The vertical cone of light from
12、 the rear lamp has been restricted to the forward sector of the cone. d) Instructions. Instructions are required to be supplied with all types of lamp. This standard supersedes British Standard AU 155 which is withdrawn. This standard also replaces BS 3648 as the current British Standard for cycle r
13、ear lamps, but because BS 3648 is referred to in UK legislation, it will not be withdrawn until such time as the Department of Transport indicates that it no longer applies to cycle rear lamps for regulatory purposes. BS 6102-1 specifies safety requirements for bicycles. BS 6102-2 specifies requirem
14、ents for reflective devices for cycles. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This docu

16、ber 2003 1 Introduction This Part of BS 6102 has been prepared in order to specify photometric and physical requirements for lighting equipment for cycles intended for use on public roads. The provision of such equipment is intended to make other road users aware of the presence of cyclists, especia
17、lly under conditions of poor visibility or at night. In addition, headlamps made in conformity with the requirements of this British Standard will provide sufficient lighting to enable cyclists at night to detect road conditions immediately ahead and, if necessary, to take action to avoid potential
18、hazards. It has been assumed, for the purposes of this standard, that the headlamp is mounted in the usual position on the headtube of a cycle, and that the beam centre will strike the road at a distance of about 16 m in front of the lamp, hence the positioning of point A in Figure 2 at 3.5 below th
19、e horizontal plane. This distance equates with the braking distance under wet conditions specified in BS 6102-1, plus an allowance for the riders perception and reaction time. Appendix A describes a suitable vibration test machine. 1 Scope This Part of BS 6102 specifies photometric and physical requ
20、irements, methods of test, and marking requirements for lighting equipment for cycles. 2 Field of application This Part of BS 6102 applies to lighting equipment for use on cycles intended to be used on public roads and, in particular, for use on bicycles complying with BS 6102-1. 3 References BS 397
