It is also useful to remember that compliance with the relevant harmonised standard(s) allows the manufacturer to place his product on the market, but the potential customer may have additional, more onerous requirements. These would be a contractual matter between the two. So, Class A may be acceptable for placing on the market under the EMC Directive for appropriate locations/environments, but the customer may state a requirement Class B, in his invitation to tender. … and yes, I was also a member of ETSI EE4 a long, long time ago … Best wishes Brian Brian Jones EMC Consultant and Competent Body signatory _____ From: [email protected] [mailto:[email protected]] On Behalf Of Mike Hurley Sent: 09 June 2006 17:38 To: 'McInturff Gary'; 'David Heald'; 'David Gelfand' Cc: [email protected] Subject: RE: EN 301 489-1 emissions question - Euro telecom center A or B classification? Gary, Your recollection is correct, Telecom centres were indeed Class B in Europe. It took us several years in the ETSI EE4 committee to get it changed to class A and even then it was by the somewhat devious means of removing emission limits from EN300 386 and instead referencing directly to EN55022. There are probably a few emc-pstc folk who remember the struggle.

Same question haunts me – I have a vague recollection that for some odd reason European telecommunications centers were Class B but I can’t find the reference. Maybe the distinction is “telecommunication centers ONLY” So I’m also interested in the answer if some one has it.

But, before just assuming that Class A is ok for telecom centers, I'd check with the telecom company to be sure that they don't have a requirement for Class B (I have this gut feel that I've run into that but I can't remember any specifics).

EMC radio equipment standard EN 301 489-1 calls out EN 55022 Class B limits in general, and Class A limits for "...equipment intended for use in telecommunication centres only,..." What is considered a "telecommunication centre?" Unfortunately I can not find any definition for this term in the standard, or in any other standards I have consulted. mc-pstc - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
