It isn't Amund's fault; the old Generic standards are defective in this respect. The bit about the mains power is in clause 1, whereas the other items are in clause 5, including ISM but not including any reference to clause 1. The British Standard version of EN50082 actually draws attention to this in the National Foreword. In EN61000-6-2, which is not identical to IEC61000-6-2, the four items are all in clause 1, including ISM, with a footnote that ISM Class A is meant. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero.
