Kevin & Listmates I broke down and decided to check out EN 50103-4. Here is what I found:
CENELEC EN 50130-4:1995 Alarm systems - Part 4: Electromagnetic compatibility - Product family standard: Immunity requirements for components of fire, intruder and social alarm systems There is an amendment - Amendment A1:1998 to EN 50130-4:1995 It supercedes generic standards, but will not be a manadatory replacement for them until Jan 01, 2001. Several observations: 1) EN 50130-4 can hardly conflict with the EMC directive. The directive is a bland motherhood and apple pie document saying thou shall not make alot of noise, and thou should not be really susceptible to noise & legal signals. 2) I asume you meant to say that EN 50130-4 and its ammendments conflict with the generic immunity standards for residential or immuEN 50082-1 or 82-2. But they are intended to do exactly that. The dirty little secret of immunity testing is that the generic standards are so generic, they are almost meaingless. Product family standards seek to improve this situation by giving more specific deatils on testing such as operating configuration of the EUT and specific pass fail criteria that better addresses the purpose and function of products in that specific product family standard. 3) >(snip) ..... . What path do you >recommend I follow to demand the repeal of these clauses?. > Were these international standards, such as the IEC, IEEE, SAE etc, you might have some path for appeal. CENELEC and EN standards are focused on Europe, and the great unwashed mongol hordes of the rest of the world (Americans, Canadians, etc.) don't amount to even a hill of beans.:):) Some would even suggest that's why they built fortress Europe, to make your life more difficult. :):) 4) Sometimes there just isn't much you can do to avoid multiple testing. If you need lab A to bless your product, and they wont take your EMC data, then you need to have them retest it or not have lab A bless your product. Probably the best way to handle things is to do your own internal testing to standards higher than the Europeans mandatory reqs, make your product pass it, and then coast thru the final Eurpoean compliance test at Lab A for certification. Several companies I know have internal EMC standards that are more severe than the European standards, because they have found out the hard way that it really is a cold cruel world out there, with real unhappy customers caused by preventable immunity failures. I hope this helps.
