本文件与ISO 10297和ISO 14246一起规定了快速释放钢瓶阀门的设计、型式试验、标记和制造试验以及检查要求，这些阀门旨在安装在可再填充的可运输气瓶、压力桶和管道上，用于输送: -无毒； -非氧化性； -不易燃；和 -无腐蚀性； 用于灭火、防爆和救援应用的压缩或液化气体或充有压缩气体的灭火剂。 注1该等快拆钢瓶阀主要应用于消防行业。然而，还有其他应用，如雪崩安全气囊、救生筏充气和类似的应用。 注2:在不存在歧义的情况下，本文件中将气瓶、压力桶和管道统称为“气瓶”。本文件涵盖了快速释放钢瓶阀作为封闭件的功能。 本文件不适用于低温设备和液化石油气（LPG）的快速释放钢瓶阀。 如果用作便携式灭火器的主要封闭件，本文件不适用于快速释放钢瓶阀，因为便携式灭火器不在运输法规的范围内。 本文件涵盖了在便携式灭火器内或作为其一部分使用的辅助可再填充推进剂气瓶的快速释放气瓶阀，如果这些气瓶单独运输，例如用于填充（见《联合国规章范本》第3.3章，特别规定225，第二注[1]）。

This document, in conjunction with ISO 10297 and ISO 14246, 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 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 and for liquefied petroleum gas (LPG). This document does not apply to quick-release cylinder valves if used as the main closure of portable fire extinguishers because portable fire extinguishers are not covered by transport regulation. Quick-release cylinder valves of auxiliary refillable propellant gas cylinders used within or as part of portable fire extinguishers are covered by this document, if these cylinders are transported separately, e.g. for filling (see UN Model Regulations, Chapter 3.3, Special Provision 225, second note^[1]).
