Foreword
This standard is equal to the second edition in 1993 and the first revision in 1994 of International mission (IEC) 60810 standard “Lamps for road motor vehicle—performance requirements”. However, GB/T -1995 “Lamps for road motor vehicle—performance requirements” referred to IEC 60810:1993 Second Edition.
Reference standard is added in Chapter 1 of this standard. The definition of “Heavy load lamp” and the heavy load test conditions of narrow band random vibration are added (see Appendix B, among them, the heavy load test conditions of narrow band random vibration is under consideration).
