IEC 60238:2020 applies to lampholders with Edison thread E14, E27 and E40 designed for connection to the supply of lamps and semi-luminaires only.
It also applies to switched-lampholders for use in AC circuits only, where the working voltage does not exceed 250V 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 used 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 60V, to be used indoors or outdoors. It 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.

As far as it reasonably applies, this standard also covers adapters.
