BS EN 61184:2017

This document applies to bayonet lampholders B15d and B22d for connection of lamps and semi-luminaires to a supply voltage of 250V. This document also covers lampholders which are integral with a luminaire or intended to be built into appliances. It covers the requirements for the lampholder only. For all other requirements, such as protection against electric shock in the area of the terminals, the requirements of the relevant appliance standard are observed and tested after building into the appropriate equipment, when that equipment is tested according to its own standard. Lampholders for use by luminaire manufacturers only are not for retail sale. Where lampholders are used in luminaires, their maximum operating temperatures are specified in IEC60598‑1 . B15d denotes the cap/holder fit as defined by IEC60061‑1 , sheet 7004-11 and IEC60061‑2 , sheet 7005-16 with the corresponding gauges. B22d denotes the cap/holder fit as defined by IEC60061‑1 , sheet 7004-10 and IEC60061‑2 , sheet 7005-10 with the corresponding gauges.
