This British Standard specifies requirements for the construction, rating, marking, dimensions and testing of travel adaptors intended for the temporary connection of electrical equipment. It applies to travel adaptors having at least one plug or socket‑outlet portion compatible with BS 1363 plugs and socket‑outlets, which are suitable for the connection of a non‑BS 1363 plug, or to a non‑BS 1363 socket‑outlet.
Travel adaptors incorporating USB circuits for charging devices are also covered by this standard.
This British Standard applies to travel adaptors intended for use in household, commercial and light industrial premises where:
-
the nominal supply voltage does not exceed 250 V a.c. single‑phase, 50 Hz to 60 Hz; or
-
the rated current of the travel adaptor does not exceed 13 A and is not less than 5 A.
Travel adaptors within the scope of this British Standard do not convert voltage.
This British Standard excludes adaptors conforming to BS 1363‑3 and conversion plugs conforming to BS 1363‑5.
