Nema classifications versus IP Ratings
Nema classifications versus IP Ratings
(OP)
I am working on reclassifying a product made in Europe to become UL listed in the USA.
The product has a IP67 rating.
I want to have it tested and listed in the most appropriate NEMA rating, but don't know what the IP67 rating is close to at all. I can't find anything on the web.
Does anyone have a suggestion?

Ironically, in examining the links you provided, the Nema classifications meet or exceed the IP ratings, but you cannot go the other way.

BTW, I don't agree with that Cole-Parmer chart on the NEMA 4 being the same as IP56. Generally, NEMA 4 equates to IP65 or 66. it's all very subjective however. Hoffman, the gold standard of enclosures for the North American marketplace, use this chart for comparison and this is the de facto authority in a lot of engineering circles.

Lastly, if you are going to do the testing, use UL. UL adopted the NEMA specs and use the same numbering system, but it is a recognized 3rd party listing agency whereas NEMA is not a true testing or regulatory authority, just a set suggested guidelines put out by manufacturers. You can get in trouble making a NEMA rating claim that is not backed up by a NRTL test report. NRTL stands for Nationally Recognized Testing Lab such as UL and ETL.
