BS 8546:2016 pdf free.Travel adaptors compatible with UK plug and socket system – Specification.
BS 8546 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 S 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.
Travel adaptors shall be so designed and constructed that, in normal use, their performance is reliable and minimizes risk of danger to the user or surroundings.Travel adaptors incorporating plug pins and/or socket-outlets for use with a country’s specific standard sheets shall conform to the dimensional requirements of those relevant standards sheets, Travel adaptors incorporating plug pins and/or socket-outlets for use with more than one country’s standard sheets shall conform to those standard sheets as far as they reasonably apply.
Type testing Unless otherwise specified, travel adaptors shall be tested as delivered in accordance with normal use at an ambient temperature of (20 ±5) C, after being conditioned at normal laboratory temperature and humidity levels for at least four days.
Travel adaptors used for the tests shall be representative of production items in respect of all details which might affect the test results.
Travel adaptors shall be submitted to inspection and tests in accordance with Table 1.
Travel adaptors shall be deemed to conform if no travel adaptor fails in the complete series of tests given in Table 1. If one travel adaptor fails in any group in the complete series of tests specified in Table 1, then travel adaptors of that type shall be deemed to have failed to conform to this British Standard, unless that travel adaptor is shown to be not representative of normal production or design, in which case a further set of travel adaptors shall be submitted to the test or tests in that group. If there is no failure in this retest then travel adaptors of that type shall be deemed to conform to this British Standard.
If more than one travel adaptor fails in the complete series of tests given in Table 1 then travel adaptors of that type shall be deemed to have failed to conform to this British Standard.BS 8546 pdf download.
