We are not obligated to apply ANY standards. If we apply those that have been notified in the OJ, we have a prima facie presumption of compliance with the Directive. If we apply any other standards, we have no such presumption, and our Declaration of Conformity is therefore weaker and more likely to be challenged. > >Related questions: > >- If more than one standard seems to apply, do you have to use all of them >in order to satisfy the standards route, or is one sufficient? There is no straight answer. We must deal with all the 'essential requirements', but that is too vague to be very useful - it doesn't do much more than tell us we must consider both emissions and immunity. We do not have to apply more than one standard for each phenomenon - e.g. we do not need to apply more than one standard that deals with high-frequency conducted emissions, but we must apply the one that is intended for our product, not one intended for quite a different product. If you really can't be sure which product standard applies, ask here for advice. We must **also** apply EN61000-3-2, and -3 or -11 (and -12 instead of -2 when -12 is published), because no product standard ENs deal with low- frequency conducted emissions or voltage changes. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero.
