Jeff,
It's a bit difficult to provide an exact answer since it's dependent on the
design of your system. Is the system approved by an NRTL? What is the
nature of the approval (i.e. listed, recognized, field investigated, etc.).

Hi Rafael,
I don't know how to exactly align UL 508C to an IEC equivalent, although
some of the learned members of this forum are sure to have suggestions.
Mine would be to contact UL. UL is well connected with a European agency

Just to add to the mix of questions so far, here's a few more that Debbie

2) Is a smart jack always to be used with the product? Who supplies it
(i.e. mfg. or customer)?
3) Is the product in

In my experience, the purpose of the end-assembly, 100% mfg. hi-pot test is

Hi,
I'm not familiar with any requirements disallowing the use of red leds (at
least per IEC 60950 and derivatives) but you'll need to ensure the LEDs (and
the application) meet EN 60825 laser class 1 requirements (ref. to cl.
0.2.6; 4.3.13 and Annex P)..

The guideline you've mentioned below is one that I've heard from UL and CSA
in the past and have applied within the realm of engineering

Hi Kurt,
I believe that under the RTTE Directive, now in full bloom, the
requirements of the LVD apply without the voltage limits.
For North America, UL 1950, third edition/CAN CSA C22.2 No. 950-M95 (the
binational standard) would likely be your best fit.

Oops,
Can't unsend the previous response so I'll apologize instead...the last

For another, possibly different point of view, you might consider contacting

Monty,
If you're serious about a cost estimate, you might consider contacting the
safety consultant(s) in a more direct manner, for negotiating purposes.
My guess is the more info you provide in terms of the product, which markets
you are targeting, etc., the more accurate a response you'll get
