Other talk-groups / repair / service shops.

Hi all, Is there anyone out there who knows of a similar talkgroup like the emc-pstc in the RF field and electronic repair field. I'm sure all of you EMC specialists ( or nearly ) repair your own tv, audio equipment and video and must have needed advise on one thing or the other. At the mome

RE: The meaning of "Affixed"

Greetings, The need to have "the last two digits of the year in which the CE mark was affixed" marked on the Declaration of Conformity is simply to make the job of enforcement officers simpler. It is bourne out of the very nature and application of the LVD in that there are many electrical produc

National Communication and Information Committee of The Russian F ederation

Re: The meaning of "Affixed"

Dear Nick and Roger: Thank you for your responses. The protocol that both of you are advocating is the one in common use, and is also what we have been advising our clients. The plain language of the Directive seems to point the other way, however. The language does not say th

Re: The meaning of "Affixed"
