Re: ce and ul listings

I really don't know the difference between the two organizations, but in regards to the code; When the code calls for material or equipment to be listed, this material or equipments specifications must be published by one of these organizations that have been approved by the AHJ. See Definitions of Listed, identified, and approved in the NEC Article 100 Definitions. :)

Re: ce and ul listings

Some states will maintain a list of approved testing agenices. do a web search for nationally recognized testing laboratory (NRTL), the NRTL orginaziation is one that many tesing labs belong to.

Re: ce and ul listings

UL is for the US (In some cases also Canada)

CE is for Europe (Centered on the EU, but some other countries also use accept it.)

The UL listing is based on testing to UL standards, while the CE marking is the manufacturers promise that the product conforms to European standards.

In the US, you can ignore the CE marking. It doesn't mean the product is suitable for use in the US. And in Europe you can ignore the UL listing.

Re: ce and ul listings

See section 90.4. Listing is one way the AHJ can assure the product is suitable for the application.
Do a search for Nationally Recognized Testing Labs
for more information on testing labs.

Re: ce and ul listings

Bryan, that is not correct. :) The standards were, for the most part, written by UL. All the NRTL's use the same product standard for testing the product (this includes CSA where they have NRTL printed on the label next to their mark). I don't know if any European agencies have gotten approval as a USA NRTL. :cool:

Re: ce and ul listings

It could be worth mentioning that several of the companies running these testing labs are international. Also, the marking on the product may not always correspond to the organisation that carried out the actual testing. There have been efforts to make the testing simpler: Now a lab can test the product and issue a test report which the various organisations around the world accept. For a fee these organisations allow the use of their respective mark, without actually having seen the product. This currently only works for a handful of products, but it is slowly expanding.

Someday, it might just say "Safe for use on planet Earth" on devices :p

TUV as "European" NRTL?

TUV as "European" NRTL?

An earlier poster mentioned that TUV was a European NRTL. They are multinational and have a group that is certified by the US Dept of Labor for NRTL lab certs (and field certs) in the US. I believe that their name is TUV of North America. So a TUV sticker on a product that is certified for Europe (EU, with CE or IEC) involves different testing/listing than would be indicated by a TUV North America label. Of course, I should have let somebody from TUV explain that better. We use TUV North America for some of our field certs.
