Here is my understanding of this issue relative to ITE. I post this both
to inform, and solicit comments which could improve my understanding.
The only U.S. Federal law I am aware of pertaining to product safety is
that covered in 29 CFR 1900 (the OSHA section). Electrical equipment

I agree with Rich's explanation (although I couldn't originally find the
right words to respond). I would like to add that the NEC (National Electric
Code) in section 300 (? - looks like someone took my copy) basically states:
an electronic product connected to the public power must be approved
Tim,
I am not aware that the different states have different approaches; however,
the local authorities, including your customer, might have different ideas,
especially with respect to safety. That is why I recommend that you
contact your customer to ask him what their expectations are
Barry,
NIST has put lots of effort to promote RC and
achieved significant results through experimental
approach. They deserved the honor of the best
symposium paper.
However, I guess we are the first team to study
RC through modeling simulation approach
building the 3-D RC model and obtaining
Hi Kathy:
Someone who seemed to believe such a edict was sent
out resently asked me to check to I asked this group.
Maybe this is just a very bad joke from someone who
really doesn't know what he is asking.
I wouldn't cross off the question this way.
Be aware that there are a
Hi Jim,
You are right. There was a Session 1A -- Reverberation Chamber, consisting of
6 technical papers, pp. 1- 29, Vol. 1, 1999 IEEE EMC Symposium at Seattle.
Besides it, there was a Tutorial Session WS3 -- Reverberation Chamber
Workshop in the Symposium as well. It comprises

Leslie,
Thanks for the valuable info.
You mentioned two articles in EMC'99 Seattle Symposium Record. Actually,
right before them on pp. 1-6 of Vol. 1 is Reverberation Chamber

Guys,
There was an entire session on Reverberation Chambers in the IEEE EMC
Symposium held two weeks ago in Seattle. You might find some good stuff in
the papers. If you are a Society member, they produced a CD-ROM of all the
papers, which is available for the asking, I'm told.

I have been informed about a standard name TL 9000 which could be adopted as
Quality standard for Telecoms industrials (soft, hard and services).
Unfortunately I have not the standard itself.
Is there a link between ISO9000-2000 and TL 9000 ?

Muriel,
we expereinced similar problems and idetified following phenomenon:
You have a loop consisting of:
PE (outlet) - Power cord receiver - receiver casing - coax cable for
measurement -

You'll have some significant HF currents flowing through this loop if
Hi Everybody,
I have some equipment that is currently under development for an
American company. While the design of the equipment still has to be
finalised, the customer requires a set of units to run on a simulator
for test purposes.
Apart from the obvious requirement that these development
First I would like to thank the group.As usual the open sharing
of ideas provides a lot of insight to me.
I have one question though - I am particularly interested in
the requirements for EN55024.
Has anyone changes their ESD procedures as a result of the
internal ESD requirement of the spec?
Dear Group,
I'm using a Strip Line Cell (S-Line) from RohdeSchwarz for doing
radiated emissions testing. Using the CISPR 22 limits of frequency
(30MHz - 1GHz), appeared a spurious signal at the frequency of
205,25MHz, and the cell was empty (no EUT inside it)!!
Well, I thought about two
Hello group,
Is anyone out there aware of an EN standard that specifically deals
with the safety of power supplies - the one in question operates on
230V single-phase and has up to six outputs one of which is as high as
1300V for a current of 0.5A.
Thank you in advance for your usual
