LEDsi lamps for general lighting services with supply voltages not exceeding 50 V a.c. r.m.s. or 120 V ripple free d.c. Safety specifications1 Scope This International Standard specifies the safety and interchangeability requirements, together with the test methods and conditions, required to show compliance of LED lamps with integrated means for stable operation, intended for domestic and similar general lighting purposes, having: a rated power up to 60 W a rated voltage equal to or less than 50 V a. c. r. m. s. or equal or less 120 V ripple free d. c., caps according to Table 1. NOTE 1

Identification

the steels specified in this standard are intended for use in heavily loaded parts of welded structures such as

smart community infrastructure and related subjects

To reveal aspects of the design that require particular attention to reliability or that present high risks in relation to the requirements (assessment may reveal that the product specification is itself inadequate)

The standard specifies compulsory functions which shall be provided on all electrical automatic control and delay devices and optional functions (options with requirements) which may be provided
