Rick, Jim,
As System Integrators this apparent easing of standards is of great concern.
Initially when the idea of the two environments was muted it seemed a good idea
and destined to make my life a little easier. Just make sure the equipment is

Brown out condition may occur during peak periods of utility usage
whereby the mains voltage drops to a level well below the minimum
voltage required to operate a critical load, and the duration of this
condition may be sec (or Hours in case of UPS, which is battery backed
up).
As I understand it, this is the Light Industrial
category. Does EN55024 (or any other ITE standard) also replace EN50082-2
Heavy Industrial?
To Jeff and everyone concerned:

Schedule is ALWAYS an issue for any testing be
it EMC or temperature. I have found that when

EMC is of minimal impact.
If we allow volume to dictate practices that are patently
wrong, then I belive we make the EMC testing pointless.

I had a look at the information, published in the EC Official Journal
on 27th February 1999, where EN55024 was made official.
In the section enabling EN55024, under the heading Reference of the
superseded standard it states Relevant generic standard(s) Note

Re CE mark,
The mark allows the free movement of goods within the EU and EFTA nations.
This is because it is indicating conformity against certain directives, which
apply throughout the union. Therefore, if a product falls within the category
of a directive, it requires the

Here's a web site for the Bureau of Standards, Metrology, and Inspection

Obviously you need to click on the English version. There you will find info
regarding the EMC regulations and the BCIQ (Bureau of Commodities Inspection

Can you recommend a lab in the USA that can perform failure analysis on an

Dear Mahesh/George
I can add a little here. Power supply vendors, and (I think safety
standards) assume that AC input voltage will be nominal plus or minus
10%. Thus the 264 volts quoted below will work with 240V +10% and the
180 volts is for a 200V supply -10%. These

Richard,
Your definitions make very good sense, with or without a lawyer's hat. The
problem is not with us. The problem is with the various regulatory

Let's don't get too far off the original path. The CE mark is just one of
the pieces of information that some directives require on the packaging. For
