I think maybe we have been snipping too much. MY reference is to the reason the symbol was proposed for inclusion in IEC 60417 - that it is less incomprehensible to the general public than an IP number. Maybe the proposal came from a country that doesn't use the Latin alphabet, whose citizens would have even more trouble understanding 'IP'? It does seem to be so that it is not called up in any IEC safety standard, BUT that would be because it ISN'T (yet?) in IEC 60417. IEC SC3C can take an awful long time to accept a symbol and standardize it. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
