scope:

Gives the rules for the international lamp coding systems and covers all lamp categories, excluding vehicle lamps. Coding for the main lamp types is specified and, for the others, will follow by amendments to this technical specification as appropriate. The object of the international coding system is: - to improve communication about the different types of lamps; - to help in discussions concerning interchangeability and compatibility of products; - to create a closer relationship between international standards and manufacturers' literature (for example the code could be given in future in the relevant parts of a standard); - to be used as a complementary marking on the luminaire; - to replace national and regional coding systems.
