Jim raises an excellent point. IMO, if such an interpretation is not forthcoming then it shall be left to the manufacturers to interprete it and state it in their documentation, just as the Performance Criteria has been left. (see the thread on that topic a few months ago!)
If standards like this one in question cannot be written sufficiently clearly, then I suggest they be withdrawn and rewritten and then carfully assessed. Some have questioned whether 61000-3-2 is even an EMC standard! Ralph McDiarmid, AScT Compliance Engineering Group Xantrex Technology Inc. From: Jim Ericson [mailto:[email protected]] Sent: November 9, 2003 9:36 PM To: [email protected]; John Woodgate Cc: Harry Hodes; [email protected]; [email protected] Subject: RE: EN 61000-3-2:2000 John: 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. It is now November 2003. The "presumption of conformity" on the old 1995 harmonic emissions standard ends on January 1, 2004. It is time to finally clarify this for laboratories and manufacturers. I will communicate with you later this week "off-line", because some of my examples of problem EUT's (and suggestions for clarifications) may breach confidentiality standards if shared with this forum. However, as a general question, if as you say, "..the committee has not received any request for an official interpretation", then where exactly can we go (as a laboratory) to request such an interpretation? 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 am requesting your personal involvement to assist in resolving this "repeatability" question. Thanks for your help!

No, because the committee has not received any request for an official interpretation. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
