Reaffirmed 2020

1 Scope

1.1 This standard applies to bayonet lampholders B15d and B22d for connection of lamps and semi-luminaires to a supply voltage not exceeding 250 V. As far as it reasonably applies, the standard also covers lampholders, which are wholly or partly integral with a luminaire or intended to be built into appliances.

Independent lampholders, for example, backplate lampholders, not specifically intended for building-in, are submitted to the additional requirements detailed in 4.

Note - Where lampholders are used in luminaires, their maximum operating temperatures are specified in relevant parts of IS 10322.

B15 denotes the cap/holder fit as given in Data Sheets 7004-11 and 7005-16 with the corresponding gauges.

B22 denotes the cap/holder fit as given in Data Sheets 7004-10 and 7005-10 with the corresponding gauges.
