Hi all,
The safety requirements under the low voltage directive are under a self
declaration procedure. This means at least 2 things in line with your
question.
First, you are free to declare compliance to the appropriate standard on
your own or with a third party (with a technical file to back

The OM (Overall Mark) is a good idea that continues to be promoted
by industry, especially multinational businesses. Oh that they had control
to proscribe it... Remember that the underlying basis for all of this is a
political issue in that nations want to control commerce
There is no requirement in the FCC Rules to include a Spanish translation of
the FCC Statement in a user manual. I do not believe that it would be illegal
though as long as the English version is present..

Let me add that screw placement (and number) is also very critical to enclosure
integrity. Having enclosure screws liberally placed along rear and sides could
lessen the need to rely on fingerstock. Most enclosures in addition to screws
along rear utilize finger contacts along sides to latch

Dan,
You are absolutely correct in questioning the need to get
certifications from all those agencies. All of the product safety
reports that I have for our products are basically the same report.
All are based on IEC950. And each one costs at least $2,000 US. Not
only that, they keep

We are currently planning to supply a single item of test equipment into the

With this we'll be up to 4 cents worth. In safety we don't have US

there were three major standards. The US controlled by UL a private

Hi Neil,
First, is a one-off a single on-of-a-kind unit?
Second, where one goes, usually more will follow.
I am not familiar with the specific requirements for test equipment in the US,

into Subpart I of FCC
We use the CB Scheme, and it does work to our advantage to a certain
extent. I only have to do the testing once and the other CB Scheme

The OM was just an example for purposes of illustration. A better name for
such a hypothetical beast would be World Mark (WM). If you read the
earlier thread, you would have read that all the agencies are getting out
of hand and that it would be nice to do testing once, then apply for a OM?
Yes - One mark, one process would be nice.

Unless your customer is a public utility or the US govt (see Rule paragraph

Dan et al,
Yes, OM, WM, or any other single mark would be much preferred over the current
system.
But, let's keep things in perspective. Years back (well, maybe not that far
back), it seemed that every counrty had its own unique approval scheme, which
included unique standards,
As you said other NRTL's can get your product certified with one

enough so that it is accepted by the general public. If they were able to
