Richard,
You mention several safety standards but not the pertinent EMC standards.
One is the EN 61000-4-4 or IEC 1000-4-4 which is called the EFT/Burst test
and it has a test for AC mains and DC mains included. For my equipment at
overvoltage category III the +/- 2kV burst is appropriate.

Richard Hughes is looking for information on mains transients...
Several sources of information are:
1) 'IEEE Recommended Practice on Surge Voltages in Low-Voltage AC
Power Circuits' , 1991, IEEE 1. Transients (Electricity) 2. Electric
Circuits - Alternating Current 3

Recently I asked some of these same questions about MOVs to the group.
Most of the products I represent need to meet IEC950 or IEC1010-1.
Some of my questions were relative to use of MOVs from line to ground. I
heard that there are some local country requirements that do not allow MOV

Patty Elliot took care of Euro requirements.
I refer you to DHHS Laser Notice No. 42, dated 18DEC89. The FDA does
not require labeling or reporting of a product that incorporates a Class

Richard,
There is a study, ANSI C62.41, that somewhat addresses your interest.
In my knowledge, there is no universal standard or published work
that details the magnitude, joule content, or frequency of occurrence
of transients since there are many sources and condition
I'm going to stick my neck out and say no.
Why? Because your product does not interface
in an optical manner in any way with the CD.
Anything that has to do with laser generation,
transmission, reception and use is completely
contained within the CD.
I believe one of the understandings with
Hello,
I used to work for a large computer manufacturer, (that was also a TV
manufacturer and an electronics kit manufacturer).
As I recall, the laser labeling requirements were that the label be on
the outside of the cabinet that contained the laser. Its int
The FDA Guide for Compliance, answers all your questions. There are
some exemptions to labelling requirements if you are using a class I
OEM unit inside your product. (like a PC, it doesn't repeat the
warnings on the outside).There are no special treatment for test

Dear Safety & EMC folks,
I am interested in obtaining data on the number, duration and amplitude of
mains transients at different parts of the mains distribution network. It
would be great if someone could point me to information published by the
IEE, IEEE or whoever.
