Perhaps, but Tyco's Raychem "XL-Trace System for Fire Sprinkler Freeze Protection Design Guide and Installation Manual" certainly contains a lot of information about how to do branch lines and sprinklers. There does not seem to be a listing reference.
http://www.tycothermal.com/assets/Americas/English/Document/Design%20Guidelines/5329/H58489_XLTrace_Fire_Sprinkler_DG_0110.pdf The local sales arm came around recently to tell us about it. It was so new to them that they actually knew nothing about it other than instructions from higher up to knock on some doors. Maybe the listing is forthcoming.
