Basic Information
Scope
Scope: This document specifies the basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage for interior lighting and optical signal devices in automobiles. This document applies to interior lighting and optical signal devices for M, N, and O-class automobiles and trailers. Main Technical Content: 2.2 Main Technical Content 2.2.1 Standard Scope This standard specifies the basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage for interior lighting and optical signal devices in automobiles. This standard applies to interior lighting and optical signal devices for M, N, and O-class automobiles and trailers. 2.2.2 Technical Requirements and Explanation of Standard Content 1) Currently, there are no GB or QC industry standards for domestic interior lights, and the definitions of various parameters are mainly referenced from the definitions in the current mainstream automobile OEM enterprise standards. 2) The electromagnetic compatibility test requirements and test methods continue to follow the corresponding provisions in Part 1 for external lights. Considering the use characteristics of interior lights, the requirement for electrostatic immunity has been added. 3) The setting of conditions for comprehensive vibration and dustproof tests is related to the actual installation position of the samples. Interior lights are also installed on the vehicle body, so the test methods in Part 1 for external lights are still used. 4) After comprehensive consideration, the waterproof test for interior lights has been removed, which is consistent with the protection requirements for electronic and electrical components installed inside vehicles in GB/T 28046.4 standards. 5) The durability of interior light switches is also very important. All automakers have corresponding operation durability requirements. Originally, this was not included due to pri
