Standard for Dry Pipe and Deluge Valves for Fire-Protection Service
Scope:
Note: The scope and ICS code for this NOI have been updated (originally published on August 5, 2020) was updated by the responsible SDO on December 20, 2022.
1.1 These requirements cover valve equipment intended for installation in piping systems to supply water automatically to dry pipe, deluge, and preaction sprinkler systems for fire-protection service.
1.2 Valves covered by these requirements may be a differential type, latched-clapper type, or a combination of these types.
1.3 The valves covered by these requirements are intended for installation and use in accordance with the following standards:
a) Standard for Low-, Medium-, and High-Expansion Foam, NFPA 11.
b) Standard for the Installation of Sprinkler Systems, NFPA 13.
c) Standard for the Installation of Standpipe and Hose Systems, NFPA 14.
d) Standard for Water Spray Fixed Systems for Fire Protection, NFPA 15
e) Standard for the Installation of Foam-Water Sprinkler and Foam-Water Spray Systems, NFPA 16
1.4 This standard does not cover low-differential dry pipe valves or valves with differentials outside of the requirement specified for differential dry pipe valves.
Project need:
AHJs are increasingly reluctant to use ORDs for regulatory requirements. There is an existing ORD that has surpassed its 5 year maintenance cycle and is no longer valid. Regulators have requested that we convert ORD in to a standard. This activity will result in a joint Canada/US standard. Manufacturers will benefit from reduced administrative burden when product only needs to be tested to a single standard. Regulators will benefit from reduced overlap in standards requirements. The proposal is to convert an already existing UL standard into a Joint Canada-U.S. National Standard by incorporating requirements from ULC/ORD-C260-1975, GUIDE FOR THE INVESTIGATION OF DRY PIPE, DELUGE, AND PRE-ACTION VALVES FOR FIRE-PROTECTION SERVICE.
