This document, in conjunction with ISO 10297:2014 and ISO 14246:2014, specifies design, type testing, marking and manufacturing tests, and examinations requirements for quick-release cylinder valves intended to be fitted to refillable transportable gas cylinders, pressure drums and tubes which convey non-toxic, non-oxidizing, non-flammable and non-corrosive compressed or liquefied gases or extinguishing agents charged with compressed gases to be used for fire-extinguishing, explosion protection, and rescue applications. NOTE 1 – The main application of such quick-release cylinder valves is in the fire-fighting industry. However, there are other applications such as to avalanche airbags, life raft inflation, and similar applications. NOTE 2 – Where there is no risk of ambiguity, gas cylinders, pressure drums and tubes are addressed with the collective term “cylinders” within this document. This document covers the function of a quick-release cylinder valve as a closure. This document does not apply to quick-release cylinder valves for cryogenic equipment, for portable fire extinguishers, or for liquefied petroleum gas (LPG). NOTE 3 – Quick-release cylinder valves of refillable propellant gas cylinders used as part of portable fire extinguishers are also covered by this document, if these cylinders are transported separately.
