Re: EMC stds
I read in !emc-pstc that Brian O'Connell boconn...@t-yuden.com wrote (in f7e9180f6f7f5840858d3db815e4f7ad1f2...@cms21.t-yuden.com) about 'EMC stds', on Tue, 5 Feb 2002: Current D of C for a component SMPS lists basic stds (e.g., 61000-4-x), but customer wants product family stds listed. Based on my limited understanding of ITE EMC stds (55022/4), it would seem that only referenced basic stds can be listed; and that the product family std can only apply to the end-use item. Correct? Comments appreciated. Partly correct, I think. There will be a product-family EMC standard for stand-alone SMPS at some date, but it is not published yet AFAIK. But Basic Standards must NOT be cited in a DOC; they are not 'notified' in the OJ and a product cannot be said to conform to them. They only specify methods of measurement. Tables of proposed limits in such standards must be regarded as **advice to product standards committees** only, not limits applicable by manufacturers, test houses or regulatory authorities. You can, of course, cite the Generic Standards. Maybe that will suffice. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero.

RE: EMC stds
Basic standards do not provide the presumption of compliance with the essential requirements. Only generic, family or product standards can do that. If you component is legally subject to a directive, then you must apply the appropriate generic, family or product standard or use the Tecnical Construction File route. The standards that you apply will depend, as you say, upon the end applications that you envision for your component. You may have to use several family standards. If your component is not legally subject to a directive, you only have to do what is necessary to keep your customers happy.

Does any one have any info on this? TIA Chaz You will have to find out what the German equivalent to TEMPEST testing, or have the equipment tested in a TEMPEST lab if theat is acceptable to them. Unless you have TEMPEST qualified people at your site, specifically a TEMPEST engineer, I wish you luck. I am not qualified in TEMPEST. Let that be clear right now. Data pick up, the ability to gather intelligence from the emissions of a device is primarily the concern of TEMPEST and entirely different than any EMI/EMC experience you may have. Perhaps a TEMPEST qualified person out there would care to comment if allowed? *** --- The comments and opinions stated herein are mine alone, and do not reflect those of my employer. --- ***
