Post by thread:[PICLIST] FCC EMI testing rules? (and OTHERS?)

I've read the FCC stuff... what other testing is required by law in the US? UL? Anything other than FCC? I've been wondering.

I've always wondered whether (for example) UL certification is a "MUST" for legal reasons or a "SHOULD" for marketing/safety/liability reasons. The FCC stuff is, of course, a MUST, but I don't know where else to look. Of course I suppose there is a specific breed of attorney that could tell me this for a substantial fee.

Your customers, or your insurers, will drive you to UL. AFAIK, It's not legally required, but I'm not current in that area. You're right though, there's a million federal regulations that you are apparently supposed to have read and memorized in school... Ignorance is no excuse as they say. -- Dave's Engineering Page: http://www.dvanhorn.org Where's dave? http://www.findu.com/cgi-bin/find.cgi?kc6ete-9 -- http://www.piclist.com hint: To leave the PICList EraseMEpiclist-unsubscribe-requestspam_OUTTakeThisOuTmitvma.mit.edu

My boss was recently on a visit in the far east, the factories out there will put any label you want on the products with no testing whatsoever!. There's a 'newish' European mark CE, which is to do with the amount of interference a unit generates, and how susceptible to interference it is. This sort of testing is extremely difficult, and there doesn't appear to be any standard tests for doing so. -- Nigel. /--------------------------------------------------------------\ | Nigel Goodwin | Internet : KILLspamnigelgKILLspamlpilsley.co.uk | | Lower Pilsley | Web Page : http://www.lpilsley.co.uk | | Chesterfield | Official site for Shin Ki and New Spirit | | England | Ju Jitsu | \--------------------------------------------------------------/ -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

They are often broken into product categories, then deal with EMC (both emissions and susceptibility) and safety as a separate standard in each product category. It's my understanding that you "self certify" compliance (and apply the CE mark). The manual on the product includes a Declaration of Conformity that lists all the standards the product complies with. A DOC of one of our products appears below. You must also have a Technical File that shows the design and the test results that were used in determining conformity with the standards. The importer (who is bringing the product into the European Community) is to present the technical file to a government representative that asks for it. We ran this stuff through a lab. With several products we were out $30,000 or so by the time we were done. I was not really satisfied with the lab. They were unaware of some of the appropriate standards, etc. A great resource for this stuff is news:sci.engr.electrical.compliance Harold 11 - Declaration of Conformity We, Dove Lighting Systems, Inc.
