Ensure the safe and effective installation of fire sprinkler systems with NFPA 13: Standard for the Installation of Sprinkler Systems. This essential standard provides the most current requirements for the design, installation, and testing of automatic sprinkler systems, helping to ensure reliable performance in controlling or extinguishing fires and protecting lives and property.
The 2025 edition introduces numerous technical updates and clarifications, including:
-
Inclusion of listed vacuum dry pipe systems in Chapter 8
-
New provisions in Chapter 7 permitting the use of vapor phase corrosion inhibitors in the air supply for dry pipe and preaction sprinkler systems to help mitigate corrosion
-
Multiple revisions to sprinkler placement criteria and allowable omissions throughout the standard
-
Updates to Chapter 4 that reorganize miscellaneous and low-piled storage protection requirements into separate sections
-
Additions to Chapter 9 allowing sprinkler omission in elevator hoistways in most situations
-
Revisions to Chapter 18, including updated load tables to account for seismic forces from piping and revised seismic coefficient (Cp) values aligned with ASCE/SEI 7, Minimum Design Loads and Associated Criteria for Buildings and Other Structures
-
For locations outside the United States, Annex E has been revised to permit conformance with ASCE/SEI 7
