  • SCOPE

    1 Scope

    1.1 These requirements cover the construction and performance, exclusive of performance during fire tests, of water fire extinguishers. Water fire extinguishers are intended to be utilized in accordance with the Standard for Portable Fire Extinguishers, NFPA 10, and the National Fire Code of Canada.

    1.2 These requirements cover stored-pressure, water fire extinguishers that use a single chamber for both the extinguishing agent and the expellant gas.

    1.3 The extinguishers covered by these requirements may be charged with plain water, an antifreeze or a loaded-stream solution. See Extinguishing Agent, Clause 23.

    1.4 The requirements for performance during fire testing of stored-pressure water fire extinguishers are specified in the Binational Standard for Rating and Fire Testing of Fire Extinguishers, ANSI/UL 711 CAN/ULC-S508.

    1.5 As used in these requirements, the term "extinguisher" refers to all extinguishers or any part thereof covered by these requirements, unless specifically noted otherwise.
