6 Type testing 6.1 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. 6.2 Travel adaptors used for the tests shall be representative of production items in respect of all details which might affect the test results. 6.3 Travel adaptors shall be submitted to inspection and tests in accordance with Table 1. 6.4 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. 6.5 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.
