Subject: Re: [PSES] OSHA and UL60974-1 Engine Driven Arc Welders

Hi John,

My name is Kevin Robinson, and I am the Director of the office that administers 
the NRTL Program for OSHA.  While this response is not an "official" response 
from OSHA (as I am sending it from my personal account), I would say the same 
thing if you were to contact me at work 
([email protected]<mailto:[email protected]>).

Before I answer your question, I would like to help set the stage a bit.  The 
NRTL Program was created by OSHA and for OSHA.  OSHA NRTL Approval requirements 
while adopted by many state and local AHJs do not officially travel down to 
that level.  Whether an AHJ would accept a certification is really up to that 
AHJ.  Additionally, only certain types of equipment 
(http://www.osha.gov/dts/otpca/nrtl/prodcatg.html) are required by OSHA 
regulations to be "acceptable" (certified by an  NRTL).  You will notice that 
engine driven arc welders do not appear on the list of products requiring NRTL 
approval, therefore, NRTL approval is not required to satisfy OSHA (but your 
local AHJ may require some independent certification).

With that said, any organization recognized by OSHA as an NRTL can evaluate, 
test and certify equipment that is not on their NRTL scope and issue a 
certification, however, if the standard is not in their NRTL scope of 
recognition (http://www.osha.gov/dts/otpca/nrtl/nrtllist.html) then they may 
not represent themselves as an NRTL (either in the quotation, contracts, but 
most importantly, on the certification mark that they authorize you to apply to 
your product.  If an organization recognized by OSHA as an NRTL were to test 
and certify a product outside their NRTL scope that would be fine.  An AHJ may 
accept that certification, but the certification would NOT be acceptable to 
OSHA (assuming NRTL certification was even required).

If you have any additional questions, feel free to contact me directly.

Hi guys,


Question on the subject -

UL60974-1 (Engine Driven Arc Welders) is not on the OSHA list of "Appropriate 
Test Standards".  UL551 (Transformer Arc Welders) is on the list.  No NRTLs 
have UL60974-1 coverage by OSHA.  Can we still use UL60974-1 for USA 
Certification?

Our issue is that UL551 does not cover our product - an Engine Driven Arc 
Welder.

Stated another way, if a Standard is not on the "Appropriate Test Standard" 
list, and no NRTLs have OSHA coverage for it, can we still Certify to it and 
have it be accepted by OSHA or any AHJ?

Thanks,

John
