RE: Telephone headsets
does anyone know about: RRL a standard/requirement in south korea? what equipment must comply to it? thank you, Richard, -Original Message- From: richwo...@tycoint.com [mailto:richwo...@tycoint.com] Sent: Friday, August 30, 2002 12:14 PM To: emc-p...@majordomo.ieee.org Subject: RE: Telephone headsets Chris, the CE marking indicates that the product complies with all applicable directives. The only two directives that might apply is the LV and EMC directives. However, the LVD does not apply since the working voltages are low. The EMC directive would apply if your equipment is likely to cause interference or likely to be susceptable to interference. I tend to believe that your equipment is not likely to cause interference, but it might be susceptable to magnetic fields. So some immunity requirements may apply. If so, your Declaration of Conformity would only claim compliance with the EMC Directive. If the EMC Directive does not apply, then no Declaration or CE marking is required.

RE: Telephone headsets
Chris, In your subject and ending you specify telephone headsets; in the body of your message you specify connection to audio amplifiers. For telephone headsets: use EN 60 950 and the RTTE Directive. Note the limit of 50 Vac/75 Vdc is not applicable under the RTTE Directive. There is really not much to comply with under EN 60 950 except for the flammability fo materials - the standard does not yet address acoustic requirements as in the UL60950 requirements. For audio/video equipment: use EN 60065 however, the LVD does not apply because of the 50 Vac/75 Vdc cutofff as mentioned in your e-mail. In this case, you may wish to consider complying with the EMC Directive and just make a declaration based on engineering judgement.

Re: Telephone headsets
I read in !emc-pstc that Chris K. Poore chr...@percept.com wrote (in kgeakhgkelfiikpbjhaiaejnccaa.chr...@percept.com) about 'Telephone headsets' on Fri, 30 Aug 2002: Is there a safety standard that we should use that is specific to these telephone headsets for EU compliance? What is the application? It is almost certain that, whether it is for household or professional use, the relevant standard is IEC 60065. But not if it's for *direct* connection to the public telephone system. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
