scope:

This International Standard applies to stand-alone indicator light units intended to give a visible signal. They are designed for a.c. only with a rated voltage not exceeding 440 V and a rated power not exceeding 10 W, for household and similar fixed-electrical installations, either indoors or outdoors.

NOTE 1 Indicator light units are not intended for lighting as a luminaire (see IEC 60598).

This standard does not apply to pilot lights incorporated in products complying with their own standards which are tested as part of that product.

The standard also applies to boxes for indicator light units, with the exception of flushmounting boxes (according to IEC 60670) for flush-type indicator light units.

Indicator light units complying with this standard are suitable for use at ambient temperatures not normally exceeding 25 °C, but occasionally reaching 35 °C.

In locations where special conditions prevail, as in ships, vehicles and the like and in hazardous locations, for example where explosions are liable to occur, special constructions may be required.

NOTE 2 LEDs and lamps are not considered as indicator light units, but as components.
