EN 60238:1996

Thi International Standard applies to lampholders with Edison thread E14, E 27, E 40, designed for connection to the supply of lamps and semi-luminaires only. It also applies to switched-lampholders for use in a.c. circuits only, where the working voltage does not exceed 250 V r.m.s. This standard also applies to lampholders with Edison thread E5 designed for connection to the supply mains of series connected lamps, with a working voltage not exceeding 25 V, to be use indoors, and to lampholders with Edison thread E10 designed for connection to the supply mains of series connected lamps, with a working voltage not exceeding 60 V, to be used indoors or outdoors. I also applies to lampholders E10 for building-in, for the connection of single lamps to the supply. These lampholders are not intended for retail sale. As far as it reasonably applies, this standard also covers lampholders other than lampholders with Edison thread designed for connection of series-connected lamps to the supply. This standard also covers lampholders which are, wholly or partly, integral with a luminaire or intended to be built into appliances. This standard applies to lampholders to be used indoors or outdoors in residential as well as in industrial lighting installations. In location where special conditions prevail, special constructions may be required.
