What does "listed for fire protection use" actually mean?
The Department of Defense specifications Section 21 13 13 calls for backflow preventers to be "listed for fire protection use". From what I have found, there is no such specific listing. Has anyone else heard of this? Thank you for your input.

I'm sure there will links to the UL listing standard for backflows posted however, check out the below site for all the current listed backflow assemblies, orientations, configurations...

For this particular product, I look for the UL listed symbol.

You can see if the backflow carries a UL listing

In addition to the UL listing, you can also check for FM approval.

Confirm if the backflow carries a UL and FM approval.

According to the principal I work for, it sure seems like listed for fire protection means "painted red and marked up." I always thought that was pretty funny and slightly accurate.

I tend to agree with the comment by Josh but I can also add that the UL listing will ensure the valving on the device is in accordance with NFPA 13. (Indicating type valve like an OS&Y Gate or Butterfly, Existence of a means of supervising per NFPA 13 such as a tamper switch, slow closing gear operation in nature to prevent water hammer) These are the items i tend to notice lacking in non-listed devices.

If you look at the information on the UL web site for UL Category BAEU it specifically indicates products in this category are intended "for use in fire service system". UL has other categories for backflow preventors intended for other applications all of these backflow preventors use UL Standard 1469 for approval, so it is important to only use equipment listed for UL Category BAEU for fire service applications.

Your reference to Department of Defense specifications Section 21 13 13 I believe is the document associated with the UFGS.
