Develop sprinkler defense for any occupancy using the most up-to-date standard. NFPA 13, Standard for the Installation of Sprinkler Systems, can help you locate and apply the latest requirements for automatic sprinkler system design, installation, and acceptance testing; hanging and bracing systems; and underground piping.

Enhance your ability to apply requirements for automatic fire sprinklers, for more effective design, installation, and code enforcement. The 2022 edition of NFPA 13, Standard for the Installation of Sprinkler Systems, is the transformative next step for designers, engineers, contractors, and installers involved with water-based fire protection in today's world.

The latest edition of this safety standard underwent a philosophical change and moved away from the use of density/area curves in favor of single point density design options for new systems, although existing systems can still use density/area curves.

Significant changes to the 2022 edition of NFPA 13, Standard for the Installation of Sprinkler Systems, include the following:
  • New supplementary requirements for nitrogen generators were added.
  • New definitions were added and several existing definitions were modified.
  • In Chapter 4, several revisions were made to delineate miscellaneous and low-piled storage requirements.
  • In Chapter 8, supervision requirements for dry pipe systems were added.
  • In Chapter 9, requirements were added to address the use of intermediate temperature residential and quick-response sprinklers; a new section on small temporarily occupied spaces was added to address conditions where pods are installed; and obstruction criteria were added for suspended or floor-mounted obstructions in ordinary hazard occupancies.
  • In Chapter 14, the early suppression fast response (ESFR) sprinkler location criteria were modified; obstruction requirements were revised to align with the results of a current Fire Protection Research Foundation report.
  • In Chapter 16, the process for determining whether freeze protection is needed was modified to require the use of the lowest mean temperature for one day, obtained for an approved source, and no longer permits the use of the isothermal map; criteria were added to address the protection of piping subject to mechanical damage.
  • In Chapter 20, criteria on multiple-row rack depth were added.
  • In Chapter 25, the content was rewritten and reorganized for clarity; this chapter now covers the single point density change.
  • In Chapter 26, special design criteria for storage applications were combined into this new chapter.
