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.
