I read in !emc-pstc that Jim Ericson <[email protected]> wrote (in <[email protected]>) about 'EN 61000-3-2:2000' on Sun, 9 Nov 2003: >The question about whether the intent of the writers (of EN >61000-3-2:2000) was to require a double "repeatability" test for each >EUT tested, or whether the intent was simply to demonstrate a "process >qualification" has been touched on in this forum for over two years.
I recall only one (your?) article on the subject. > >It is now November 2003. The "presumption of conformity" on the old >1995 harmonic emissions standard ends on January 1, 2004.

OK, feel free to do so.

You are in the USA, so you should go to the US National Committee. There is, I suppose, a TAG for IEC SC77A, and it seems to have been very active. But I don't know where or whether you (in USA) can find the membership list. I'm fairly sure that people outside USA can't find it. > A >LITERAL interpretation of the "English" language text in the 2000 >standard means that many of our customers will have a big, big problem >on January first, 2004. I don't agree. My 'literal' interpretation differs form yours, but I agree that a clarification is necessary. A clarification is almost always necessary when someone reports a problem of this nature. > >I am requesting your personal involvement to assist in resolving this >"repeatability" question. I will do what I can, but I cannot do everything. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
