scope:

This standard shall be used jointly with EN 60309-1, EN 60309-2 and with the relevant National Standards for socket-outlets (listed in annex AA). It applies to conversion adapters intended mainly for industrial use, comprising a housing of insulating material, which incorporates an industrial 2P + earth, 16A, 6h, 250 V a.c. type plug part (table 104 in EN 60309-2) and one or two socket outlets in accordance with the relevant National Standards for socket outlets for household and similar use, with a rated current up to 16 A intended mainly for industrial use either indoors or outdoors. This standard applies to all applications where the ambient temperature does not normally exceed 40 °C. The use of these adaptors on building sites, for agricultural, commercial and domestic applications is not precluded but care should be taken in considering protection devices in use. Adaptors are for temporary use only. In locations where special conditions prevail, for example on board ship or where explosions are liable to occur, additional requirements may be necessary.
