Re: Compression Fittings
I have contacted UL and my understanding of this issue is:
There is a new standard for compression fittings, and to date no manufacturer has complied, although one company has submitted a fitting and it did not pass the standard.
The existing fittings do pass the older standard and the 2002 NEC has recognized them, so until such time, the older fittings can still be installed, and that is why one can still see them being sold as listed.
This is what the UL rep told me.
The NY Board of Fire Underwriters in NY has not passed down a ruling on this issue yet, so I believe they are allowing the installation of Emt in wet locations with the existing type compression fittings.
