I found the following web site for MEEI, HUNGARIAN INSTITUTE FOR TESTING AND CERTIFICATION OF ELECTRICAL EQUIPMENTS. http://www.omikk.hu/trebag/meei/angol/meeia.htm . According to the site, safety certification is mandatory for certain equipment in

Are Safety Approvals Required for Telephone Adapters?

We are looking at Telephone Adapters, such as those made by TeleAdapt ( http://www.teleadapt.com/web/Catalogue/Index), to go from an RJ-11 plug to phone jacks for the following countries: (Embedded image moved to file: pic14566.pcx) We have seen some adapters with UL, TUV, and CE marks. The only

RE: Alarm bell box

My opinion is that EN60950 would apply if the equipment is for business use only. Otherwise, EN60065 would apply for household use and "similar" purposes. However, you should ask a Notified Body for an official opinion. You did not ask, but EN50130-4 would apply for immunity effective 1/2001. I as

RE: Compliances

Brian, No, I cannot, but if you would like to express this question in terms of some equations (preferably, Maxwell's Equations in either differential, or integral form) then perhaps I could come up with an answer! Jim Dr. Jim Knightene-mail: jlknigh...@ieee.org

RE: Characterizing a screen room

Here's a caution on conducted testing in a screen room, too: While testing a power supply at a former employer, I noted it was failing in our lab, and passing in another, with the same load board and using the same type of LISN. The failure was due to our test setup; radiated noise from the load

Alarm bell box

I've been asked to give an opinion on an intruder alarm bell box. EN guidance (CENELEC report R079-001:1998) indicates that either EN60950 or EN60065 may be appropriate for safety, and sooner or later I'll have to make my own mind up as to which to choose. However, if there's anyone out there would

RE: Characterizing a screen room

A screen room will be useful for conducted emissions but not radiated. Go with the parking lot for radiated. It's cheaper and will yield better results. -- From: plaw...@west.net [SMTP:plaw...@west.net] Sent: Tuesday, April 27, 1999 5:00 PM To: emc-p...@m

RE: Colors of indicators

Hi Folks This has been a "thorny" problem for the last 20yrs to my personal knowledge! I first encountered it in the late 60's/early 70's with IEC 204 (the predecessor to EN60204) and with medical equipment for use by the UK National Health Service. Over that period, the recommended colours h

Hi group A nice simple question after all this High level maths which has been going on regarding Harmonics. Can any one point me in the direction of a web site which lists the countries that now require mandatory compliances for EMC and Safety and if possible the marks that are req

Re: Colors of indicators

Hi Jim, The first time I came across this requirement was when carrying out GS approval on a PC. It came from the German ergonomic standard ZH1/618. Regards, Chris. "Allan, James" on 27/04/99 13:27:21 Please respond to "Allan, James" Sent by: "Allan, James" To: "'emc-pstc'" cc:

Re: Heat Calculation

Scott: Heat output from electronic products can be calculated using the formula: btu / hour = Watts * 0.29307 Also, you can check out the following website for other useful conversion factors: http://www.megaconverter.com/Cv_start.htm
