Was at an NRTL/CAB site yesterday. Noted a small group lurking - assessment
engineer said they were part of an OSHA audit team. I recognized one member
of the audit team from another NRTL down the road.
Does the U.S. OSHA use NRTLs to audit each other?

Many companies can not justify the cost of a measurement chamber for radiated
emissions - not to mention the cost of an EMC engineer to run it. I completed
an article on how I set up temporary radiated emissions measurement test sites

I would like someone to verify my thoughts in IEC 61010-1:2010 section 16.2
d) Ergonomics Aspects - arrangement of TERMINALS.
This clause is a bit obscure (possibly incomplete) and to be honest makes
no sense in the ways I have seen it used so far. This new section 16 is

Brian,
NRTLs are under to oversight of OSHA, although I was not aware they would
do field surveys like this.

OSHA only uses OSHA employees to conduct NRTLaudits and assessments.
The NRTL program does not operate on a peer assessment type of
system.

Am aware of the OSHA requirements for NRTLs (29CFR1910.7), as I was recently
involved in an issue pertaining to the legal requirements vs internal policy
of a test lab.
CAB accreditation programs in North America are not as transparent as the
legal code would indicate. Vee have vays, I vill
Hello All,
I have recently been tasked with writing a set of questions that job
candidates would need to answer at the same time they apply for a
position requiring knowledge of product safety evaluation, testing
and practices. These questions would serve as an automated pre

When I was at TUV the OSHA auditors for our NRTL accreditation were actually
from the Department of Mines if I remember correctly but maybe it has changed
in the last 12years?
For our CB accreditation CENELC did use auditors from other notified bodies
like CSA and VDE.

Could it be that the NRTL you visited recently hired the other NRTL staff
member?

Well don't try - what is the sound of one hand clapping I asked Siri (iPhone

Try to avoid definitions and work the question so they have to demonstrate

You might try, if you have inadequate creepage distances
In the 1980s, I believe MSHA(Mine Safety and Health Association)performed our

I guess that makes me old.

This has the makings of an extremely esoteric pub quiz, if we're not careful!
Here is one, adapted from a phone enquiry I dealt with this morning this
morning:
You have two appliances. One is marked 110 - 230V ~50Hz and the other is
marked 110/230V ~50Hz. What do you look for on one which is
You could ask them for a hipot voltage per 5.2.2; I don't believe the table
is available via google; you would also be able to evaluate their useage
of the table, conversion from RMS to Peak voltage, AC vs DC, etc.
You could also ask them to summarize the requirements for a fire or
mechanical
Not sure this is what you are looking for; but the 110-230V unit is rated
as a range, so the tolerance would be below 110 and above 230. The 110/230
V has two distinct rating ranges, so the tolerances would be above and
below 110 AND above and below 230VAC. That's the first thing that pops
into
Pre-screens that attempt to minimize consumption of a candidates' time is a
good thing.
What if the candidate logs in to answer one or two questions that evaluate
engineering judgment and/or problem solving? Perhaps you have to consider
that the knowledge of... stuff cannot be used as a

assessing this type of knowledge, but if you have to have questions on an

And a voltage switch is NOT necessarily required. Think auto-switch power

Hi Scott,
That's not always the case. I've had experience with auto-ranging 120/240V
products where no voltage selector switch was needed.
