The crunch argument would be that no TV or radio receivers would be likely to be within 10 m (preferably 30 m) of the product. -- OOO - Own Opinions Only.

RE: EN 301 489-1 emissions question
David: All: To claim compliance with EN 301489-1 (I am looking at V1.6.1), Clause 8.4.3 Limits, the way the clause is worded, your equipment is not installed in a telecommunications center as one would infer from ETSI TR 101 651. The reason for Table 9: Limits for conducted emissions of equipment intended to be used in telecommunication centres only is to be in alignment with EN 300 386, which does allow Class A conducted emissions limits, as previously discussed. It appears you will be having to comply with the Section 8.4.3; Table 8, Conducted Limits. William T.

RE: EN 301 489-1 emissions question - Euro telecom center A or B classification?
Everyone 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: emc-p...@ieee.org [mailto:emc-p...@ieee.org] On Behalf Of Mike Hurley Sent: 09 June 2006 17:38 To: 'McInturff Gary'; 'David Heald'; 'David Gelfand' Cc: emc-p...@ieee.org Subject: RE: EN 301 489-1 emissions question - Euro telecom center A or B classification?

In message a3772c119941df41977965de844184d8ecc...@telefic.telefication.com, Willem Jan Jong wjj...@telefication.com writes Class A indeed applies for products meant for the general public. Class B products are meant for industrial users (e.g. telecom providers) operated by occupational workers. Surely it's the other way round. Class A is 'industrial', excluding 'light industry', which requires Class B, along with 'commercial' and 'residential'. You just might be able to get a Notified Body to agree that no radio or TV receiver is likely to be within 10 m of your product, and thus Class A could be permitted. At some point, these classes will have to be revisited, because many Class A products have found their way into homes, with no obvious adverse consequences. Furthermore, some spectrum management authorities in Europe now regard the LF and MF broadcast bands as 'unprotectable' because of the general level of 'EMC smog', quite a lot being contributed by large numbers of Class B-compliant products. In addition, because the emission limits are based on separations of 3 m, 10 m or 30 m, there is no protection against a receiver being interfered with by a small SMPS only 30 cm away, maybe even its own power supply! -- John Woodgate - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.Website: http://www.ieee-pses.org/ To post a message to the list, send your e-mail to emc-p...@ieee.org Instructions: http://listserv.ieee.org/request/user-guide.html List rules: http://www.ieee-pses.org/listrules.html For help, send mail to the list administrators: Scott Douglas emcp...@ptcnh.net Mike Cantwell mcantw...@ieee.org For policy questions, send mail to: Jim Bacher: j.bac...@ieee.org David Heald:emc-p...@daveheald.com All emc-pstc postings are archived and searchable on the web at: http://www.ieeecommunities.org/emc-pstc
RE: EN 301 489-1 emissions question
Although not defined as such, telecommunication centres (Major and Minor) are described in section 5 of ETSI TR 101 651 (free download from www.etsi.org). They generally relate to the ‘public telcoms network’ A ‘point-of-sale terminal system with a rooftop antenna’ would certainly not be a ‘telecommunication centre’ in this context Mike Hurley Director Mead testing ltd Units 23/25 Mead park River Way Harlow CM20 2SE mikehur...@meadtest.com www.meadtest.com phone 44 (0) 1279 635865 fax 44 (0) 1279 635874 From: emc-p...@ieee.org [mailto:emc-p...@ieee.org] On Behalf Of David Gelfand Sent: 09 June 2006 13:25 To: emc-p...@ieee.org Subject: EN 301 489-1 emissions question I need help from our esteemed CE mark experts!
