Jeff,
Mr. Eszlari asked, Is it true that European safety agency approval for
critical components may not be required for CE?
Answer, No, it is NOT required (compulsory) for a manufacturer to use
European safety agency approval for critical components. Having a
certificate from an accredited
Yeah, I second that. I try to believe in as little confirmation as
possible. Extended stacks of paper don't verify anything. For the EMC
stuff I think that you really want to deal with labs that have NIST
approval through NVLAP or A2LA. Among other things if you don't need an
FCC ID you can ship
Thanks all for your fast helpful responses.

Greetings,
For those of you that may be interested in EN 60950 and all other clones of
IEC 950, I have scanned and OCR'd the latest List of Decisions, as of July
1998.

I absolutely disagree about having a separate ground for the shielded room.
Any ac fault inside the room can potentially cause a personnel hazard, as
will any lightning strike to the vicinity. A separate ground for the
shielded room is acceptable ONLY if it is bonded to building ground. The

all of the requirements that testing and calibration laboratories have

Kate,
My apologies for the apparent slight. In the US, where I'm located,
NVLAP and A2LA were simply familiar to me. I happen to us NVLAP when I
qualified a former employers site. Quite possibly their are more
certifying bodies in the US than just those two and if they carry NIST
credentials I

Hi Ed,
Yes, I agree. The way you suggested is an ideal method to get Ambient noise
in the Conducted emission test. Please allow me to make two more points
about impedance vs. frequency:
(1) It is inconvenient in practice to find a resistive load sized to draw
the same amount of power. We

Hi Group,
Do you know where I should go for renting a EFT/B Generator to run

Thank you.

Mike,
sorry you disagree.
Inside the room, all equipment is referenced to the room itself, there is no
new safety risk introduced by the room being grounded differently.
Outside the room, again, all equipment is referenced tightly to the room, so
the operator does not see any differential.
We have a new display panel design that requires a a small switcher for
power. The end product must meet Class B emissions. We are planning
on using the Linear Technology LT1376 IC which contains the control
circuitry and switch. It operates at 500KHz and is rated at 1.25 amps.
Has anyone had

Michael Hello,
1. You state a piece of equipment. Is this piece going to be
integrated into an end-product? If so, it is wise to ask the Irish end-
product manufacturer or installer, what the requirements (EMC,
Safety, etc.) for the end-product are and work accordingly.
Otherwise, you may be

Is Ozone a toxin?
Many years ago I had a factory inspector threaten to close down some High

Lately we have had bad vibes about a Xerox copier making too much Ozone and
