Description / Abstract:
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.
These requirements cover stored-pressure, water fire
extinguishers that use a single chamber for both the extinguishing
agent and the expellant gas.
The extinguishers covered by these requirements may be charged
with plain water, an antifreeze or a loaded-stream solution. See
Extinguishing Agent, Clause 23.
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.
As used in these requirements, the term ²extinguisher² refers to
all extinguishers or any part thereof covered by these
requirements, unless specifically noted otherwise
