Although some would get the impression from the text that these levels are regulatory test levels, they are **guidance for product committees when writing product EMC standards** and have NO regulatory validity. You must use the level specified in the relevant product EMC standard (an EN55xxx standard) or the generic EN61000-6-x if there is no product standard. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
