The levels of safety are described by code letters. The following URL will (with a following electric wind) give you a list of the relevant IEC standards. This is on the publicly-accessible part of the IEC web site. http://www.iec.ch/cgi-bin/procgi.pl/www/iecwww.p?wwwlang=E&wwwprog=sea22 .p&search=text&searchfor=60079&Submit=OK -- Regards, John Woodgate, OOO - Own Opinions Only. The good news is that nothing is compulsory. The bad news is that everything is prohibited. http://www.jmwa.demon.co.uk Also see http://www.isce.org.uk This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
