1.1* Scope. This standard covers the requirements for new adjustable-pattern spray nozzles intended for general firefighting use, for marine and offshore platform fire-fighting use, or for use with fire hoses affixed to standpipe systems. A.1.1 While nozzles meeting the requirements of this standard are designed to be used in fire suppression, including hose lines on standpipe systems, the nozzles cannot be expected to provide satisfactory performance if adequate water pressure and volume are not available. Pressures available in standpipe systems are often controlled by pressure-reducing devices. Fire departments planning to use spray nozzles with standpipe systems should ensure the standpipe system can supply the necessary pressure and volume. The inspection and care of in-service nozzles is covered by NFPA 1962.
