>> At least one standard calls up IEC801-5, which simply does not exist.
John, I found reference to a draft IEC801-5 and it appears it is the surge immunity, now IEC/EN 61000-4-5. Just so that I know where you're coming from, are you saying the reference (number) is completely wrong or that the draft never got to see the light of the day and should have never been called up?

Am I not correct. AFAIK, the position is far from clear. The ENVs have been described as 'superseded' by ENs in the 61000-4 series, but do not seem to have been 'withdrawn'. Nevertheless, much of their content is now seriously out- of-date. It can just as well be argued that you must use the EN instead, because it is a 'better' standard, i.e. more certainly ensures that the 'essential requirements' are met. >Case in point, EN 50130-4 Product Family Standard for Alarm Systems calls >out specifically ENV 50141 not EN 61000-4-6. I know: see my other post saying that I am taking this up through BSI to get a general clarification from CENELEC. At least one standard calls up IEC801-5, which simply does not exist. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero. ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
