I'd like to respond.
I just read the Federal Register notice (go to this URL and click on the
second item)
http://frwebgate.access.gpo.gov/cgi-bin/multidb.cgi
There are no requirements for LEDs NOW in the 21CFR 1040. In 1992, the FDA's
CDRH
published an NOI (Notice Of Intent) to update 21 CFR

Hi Jim:
1. Am I correct that the North American agencies (CSA, UL, ETL, etc.)
allow line-to-ground MOV's? The standards we work with do not
disallow
them, but this is the sort of issue for which agencies often invoke
desk drawer requirements.
Can't answer this one.
But, why use surge
Thanks to all the responses.
A suggested off line contact with one of the
persons involved with the limits produced
confirmation of much of what has been said.
If I may take the liberty to paraphrase his
response - it was determined to prevent radio
interference at an agreed upon
Hello Group,
I few years ago I remember seeing an article in one of the EMC/ Approval
trade magazines with some in depth country lists of what frequencies were
available for spread spectrum use. Does anyone remember that article and can
they point me to it, or alternatively does anybody know of
I too am re-posting an e-mail. I'm pretty sure this one did make it
onto the forum, but I've only received one reply, so I am begging for
more, particularly to my questions 2 and 3 below.
Thanks,
Jim

The RTTE Directive says the LVD will apply with no lower voltage limit;
however, it is not clear to me if internal battery operated equipment with
no recharge connections is subject to the LVD. Article 1 of the LVD seems to
imply that the directive applies only to devices with external power
This bounced yesterday, so I am resending it.

This is reposted because I believe it went into the bit bucket the first

Pehaps you can help me overcome an area of some confusion to me.
If our radio products are AC powered from a line cord, we get UL listing,
CSA certification, etc. No question.
But what if a radio is DC
Greetings,
I have just received the following message from a colleague. I have not
verified this personally, but I thought it would be of interest to this forum.
The FDA published in the Federal Register on March 24, 1999, a request for
comments from the public to remove LEDs as devices
Bob,
I don't know if this will help you with your situation but you may want
to check out clause 1.1.3 of EN 61010-1:1993.
It has a note that states similar equipment within the scope of IEC 950
and complying with its requirements are considered suitable for use with
equipment within the scope
Bruce,
DB has identified a very likely source of the problem. From your
description, the high value of surface transfer impedance of the shield of
the cable assembly occurs at the connectors, rather than along the braid,
itself.
An experiment to verify this would be to sacrifice a cable
The ITU regulations give an indication where the CISPR levels are coming
from;-
The ITU-R (BS.412) recommendation for minimum useable field strength in
urban areas is 54dbuV/m (for FM stereophonic service) and defines a
radio-frequency co-channel protection against steady state interference of
Lothar,
Of all the DofC's I've witnessed in my travels that have been generated from
test labs, very few have required the manufacturer's signature. In fact, they
were signed by an officer of the test lab. However, to be fair, these DofC's
issued from test labs may be only intended for
