Thanks, and, now that you have reminded me, I do seem to remember BS1363-5 (but, TBH, I haven’t been taking a great interest in the evolution of standards over the last few years, having retired in 2015! 😊). So as John Woodgate has now pointed out to me, the correct standard for such adapters is BS 1363-5:2016 “13 A plugs, socket-outlets, adaptors and connection units. Specification for fused conversion plugs” – and, again, a good summary of the scope & contents can be found on the ANSI webstore here https://webstore.ansi.org/preview-pages/BSI/preview_30391432.pdf Apologies for the error of omission!

That standard is indeed withdrawn and should not be used. BS 1363-5 is valid. ====================================================================================== Best wishes John Woodgate OOO-Own Opinions Only www.woodjohn.uk <http://www.woodjohn.uk> Rayleigh, Essex UK Istae nunc praetereunt nisi non ubicumque On 2022-04-28 11:14, John E Allen wrote: Morning AFAIK, the most appropriate British Standard would appear to be: BS8546: 2016 “Travel adaptors compatible with UK plug and socket system. Specification” https://shop.bsigroup.com/products/travel-adaptors-compatible-with-uk-plug-and-socket-system-specification-1/standard There is a confusing reference to “Withdrawn” on that webpage, but I don’t think that it has been! It also incorporates by Normative reference a very large number of other BSS as here: https://shop.bsigroup.com/products/travel-adaptors-compatible-with-uk-plug-and-socket-system-specification-1/standard/details The most detailed description of the scope of that standard that I could find quickly seems to be here on the ANSI webstore: https://webstore.ansi.org/preview-pages/BSI/preview_30377194.pdf On a more general level, BS 5733: 2010 “General requirements for electrical accessories - specification (+A1:2014)” https://shop.bsigroup.com/products/general-requirements-for-electrical-accessories-specification/standard is used to assess many types of “electrical accessories” such as cable extension sockets and “plug-in accessories”, and, again, implements by Normative reference other BSS to cover specific aspects of design & construction. Again, the ANSI webstore site gives helpful detail, https://webstore.ansi.org/preview-pages/BSI/preview_30288272.pdf Obviously you can buy elsewhere, including BSI’s own website here https://www.bsigroup.com/en-GB/standards/!

Hi We have been checking several travel adopters for importers here in EU, but we have to fail nearly all of them. One big issue is the UK plug. As I understand they shall comply with BS 1363-3. And in this standard §12.4 e) there is a requirement for BS 1363 or BS 643 fuses. Some adapters have an 5x20 IEC fuse some have thermo fuses and many have no fuse at all. Do I overlook some exceptions or new requirements, that allows adaptors without BS fuse, or are they all just "normal" Asian low quality?
