Make sure spray nozzles will operate as expected in a fire emergency with the 2013 NFPA 1964.

NFPA 1964: Standard for Spray Nozzles provides the latest performance requirements for new adjustable-pattern spray nozzles intended for general fire-fighting use, for marine and offshore platform fire-fighting use, or for use with fire hoses affixed to standpipe systems.

Provisions cover all the bases, including:

  • Operational design
  • Construction materials
  • Test methods
  • Compliance testing

In the 2013 edition, the term "Flow rate" replaces the term "Discharge rate" to emphasize the importance of flow rate for the suppression of fires. NFPA 1964 is essential for nozzle manufacturers as well as fire departments and companies that provide testing of fire hose nozzles. (Softbound, 15 pp., 2013)
