This International Standard specifies requirements for miniature halogen and non-halogen lamps with a nominal voltage up to 30 V and a nominal wattage up to 25 W. It covers: – lamps to be used in road vehicles not subject to regulation and which therefore are not included in IEC 60809 (section 2); – lamps for electric torches (section 3); – lamps for miners’ caplights (section 4). Aircraft lamps are standardized in IEC 60434. This standard specifies dimensional, electrical and photometric requirements as well as requirements concerning life and mechanical strength. NOTE Requirements are for production lamps. Individual lamps might not be completely within these requirements. Where conditions of compliance are required, they are specified in the relevant section. For some of the requirements given in this standard, reference is made to “the relevant lamp data sheet”. For some lamps these data sheets are contained in this standard. For other lamps, falling under the scope of this standard, the relevant data are supplied by the lamp manufacturer or responsible vendor. This Standard may also be used for future developments, e.g. where the light is produced by light emitting diodes (LED).
