The rest is recommended.
This standard was drafted in accordance with rules GB/T 1.1-2009 given.
This translation method using identical with standard ISO 6742-2. 1985 "Bicycle lighting and optical reflecting means and the second physical requirements
Part. reflecting means. "
This standard made the following editorial changes.
--- is consistent with existing standard series, the standard name to "bicycle reflecting means";
--- For ease of use and more intuitive to reflect the colors of the reflector optics required technical parameters, based on ISO 6742-2. 1985
5.1 provisions clause 5.1 of this standard yellow reflector increases light intensity coefficient table 2 and the red reflection light intensity coefficient
Table 3, so the number of the table have been adjusted after it (see Chapter 5, Chapter 6, Section 7);
--- ISO 6742-2. 1985, clause 7.2.2.9 version cited "3.2" as a clerical error, this standard has been corrected to reference "5.2."
Consistency correspondence relationship with the international standard in normative documents referenced in our files are as follows.
Safety requirements for bicycles --- GB 3565-2005 (ISO 4210.1996, IDT);

3 Terms and Definitions
IEC Publication No.50 (45) define the following terms and definitions apply to this document.
3.1
Reflecting means retro-reflectivedevice
Reflector reflector
You can reply by one or more light reflecting units of readily available components.
3.2
Wide-angle reflectors wideanglereflector
Means for retroreflection sides of the axis from the reference level is not less than 50 ° angle of incidence of light can be made.
3.3
Common reflector conventionalreflector
Means for retroreflection sides of the axis from the reference level is not less than 20 ° angle of incidence of light can be made.
4 Application symbols and units
The following symbols and units apply to this document. see picture 1.
Note 1. The following symbols are predetermined in accordance with a UN/ECE No.3 about return reflection means).
1) see document E/ECE324-E/ECE/T RANS/505- Appendix 2/correction 1, No.3 states. reflecting means on the vehicles and their trailers
Terms of unity.
FIG 1 illustrates the application symbols
A. Reply effective area of the reflecting surface means, unit. cm2;
C. reference center;
NC. the reference axis;
Rr. a receiver, the visualizer or measurement devices;
CR. receiving center;
φR. Rr If the receiver is circular, its diameter means, unit. cm;
Se. a light source;
Cs. the light source center;
φS. a light source diameter, unit. cm;
De. Distance from the center of the light source to the reference center C Cs, unit. m;
D'e. the distance from the receiver to the reference center CR center C, unit. m;
Note 2. In general De and D'e is almost the same, as viewed under normal circumstances, it can be assumed to De = D'e. In order to achieve artificially increased measured
When the amount of the targeting system used from the effective distance may be employed.
D. The average diameter of the return reflected on the reflection of the tire ring, unit. mm;
α. angle of observation;
β. the angle of incidence. Given CsC always considered as horizontal straight line, so that when the reflection means for, in accordance with the NC axis with respect to the light source Se
Line position, the incident angle is defined as the symbol. is a left (-), the right is (), of the (), is lower (-). Angle may be in any direction
Is determined by two angles, i.e., the vertical angle and the horizontal angle, vertical angle is always EDITORIAL;
γ. see Rr is the aperture angle of the receiver from the point C;
δ. Se aperture angle of the light source seen from point C;
ε. the rotation angle. Facing the illuminated surface, when rotated c...
