Duncan, I've had the scenario with my end product (very simple product - metal enclosure, SELV printed circuit, 150W Recognized component Power Supply, Recognized Input module. That's it.)
I had it listed with NRTL B. Market pressure forced me to get NRTL A's listing mark - to the same standard. NRTL A would not accept ANY data (not just test data, even part number info - I had to send the complete package again). While I don't like to pay twice for the same thing, and while I was exposed to what amounted to be different interpretations (between the NRTLs) of the specifications causing great frustration . . . I looked at it from a different point of view. Don't get me wrong, I do sympathize with you, and I wish they had an MRA between them - it would save a lot of time, money, and frustration . . . but I can see NRTL A's point. If a customer came to me with a product and wanted it listed with my mark, before I put MY mark on it (which, historically, most consumers consider a quality indicator) I would make damn sure that the product was compliant, lest I incur the wrath if it fails. I wouldn't take anyone's word for it (report or not) and rubber stamp it.

Group, What about another scenario that I have been in with two NRTL's. For the sake of embarrassment,lets call them 'NRTL A' and 'NRTL B' Firstly any components or equipment recognised or listed by an NRTL are deemed 'acceptable' to OSHA so long as it is used as prescribed in its conditions of acceptability or use. so can I presume that as OSHA accepts any NRTL mark they are all of equal standing. Why is it then that NRTL A will not accept a power supply approved by NRTL B. The latter is true for NRTL B who will accept NRTL A's mark with no problems (in all cases the conditions of acceptability are followed) So long as the conditions of acceptability are followed and there are no engineering reasons for NRTL A to reject NRTL B's approval then what happens next. Is there any recourse or would we have to go to one NRTL and get the whole lot retested. If there is no engineering reason, can an NRTL reject anothers recognition just because it distlikes it or maybe sees it as competition! Has anyone else had a similar experience, if so what did you do to resolve it without paying out for more NRTL approvals on an already recognised component. Any comments would be greatly recieved.
