Reverberating chambers and screen rooms

[Aschenberg, Mat]

I was wondering how feasible it is to convert a screen room into a
reverberating chamber? 
How useful are reverberating chambers in measuring radiated emissions?

Hello, everyone:

We would like to buy the following EMC standards (US and Europe):

1.  CISPR 22
2.  IEC - 1000 - 1,2,3,4
3.  FCC CFR 47, Vol.1
4.  ANSI C63.4

I suppose that these are the most frequently-used standards in EMC
testing.
(Do I miss anything ?). I would appreciate if anybody could tell me
where I
can buy these standards.

fax: (508) 486-8828

She has been very helpful in providing me with all of the standards I have 
needed.  In addition to the specs you listed, you might consider purchasing 
the European Norm for the Immunity requirements.  The Generic Norm being 
EN50082-1 for light industrial equipment, while if your products fall in 
the category of ITE, then you would want to pick up EN55024.

Hope this helps!

Re: Australian electricity supply

[Chris Healy]

Any thing other than 415/240 will be a problem. 240/120  or 480/240 does not 
exist
in the normal distribution system. Where these exist it is from a specific
customer installation.

It is my understanding that the 250V areas of Western Australia are now the same
as the remainder of Australia and have been for some time.

RE: Australian electricity supply

[Geoff Haines]

Hi Everyone,

Australian mains voltage is due to change in line with European voltages.
See the info on the link below:

http://www.standards.com.au/standardization/electrotechnology/news/1999%2D03%2D25/1999%2D03%2D25.htm

Currently we are on 240V, the tolerances are +6%, -6%.

Perth is now closer to 240V than 250V.

european community meeting

[Lou Gnecco]

Group:
Yesterday the US Dept of Commerce held a meeting  regarding the EMC
annex of a Mutual Recognition Agreement being worked out between the US and
the european union. The idea is to work out procedures where american emc
labs will be recognized by the europeans as full-fledged "competent bodies."
that is, to give us the same status the european emc labs.

Before we all jump for joy, this looks like the first step towards
replacing our FCC rules with the vague, arcane amd constantly changing
european standards. This would enrich the emc labs (like us) but would put a
big burden on all manufacturers, specially small businesses. I think that in
the long run this would be very bad for our economy.

Anyway, I went to the meeting & brought back about 50 pages of
handouts, with some interesting stats. For example: last year the Germans
failed 44% of the domestic radio and tv sets they tested. They hit
manufacturers with a total of 418,000 Marks in fines (about  $200,000). This
doesnt seem like much, until you figure that each european country is about
as big as one of our states. multiply by 50. 
 
There is too much material to post on our web site. If any one is
interested, Ill send you a copy for the cost of printing and postage. $10
ought to do it.
Send to TEMPEST INC. 11654 PLAZA AMERICA DRIVE, RESTON VA 20190

Note: we are doing this as a service to the group. This is not a
commercial, so please don't dump us off the reflector (again) Rich!  ;)

Regards,
Lou
