25、lations). Additional features of a quick-release cylinder valve (e.g. pressure regulators, residual pressure-retaining devices, non-return devices, and pressure-relief devices) might be covered by other standards and/or regulations.This International Standard has been written to be in conformity wit

26、h the UN Model Regulations. When published, it will be submitted to the UN Subcommittee of Experts on the Transport of Dangerous Goods with a request that it be included in the UN Model Regulations.Where there is any conflict between this International Standard and any applicable regulation, the reg

27、ulation always takes precedenceIn this International Standard, the unit bar is used due to its universal use in the field of technical gases. However, it is noted that bar is not an SI unit, and that the corresponding SI unit for pressure is Pa (1 bar = 105Pa = 105N/m2).Pressure values given in this

28、 International Standard are given as gauge pressure (pressure exceeding atmospheric pressure) unless noted otherwise.

29、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 which convey non-toxic, non-oxidizing, and non-corrosive

30、 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 applicati

31、ons such as to avalanche airbags, life raft inflation, and similar applications.This International Standard covers the function of a quick-release cylinder valve as a closure.This International Standard does not apply to quick-release cylinder valves for cryogenic equipment, for portable fire exting

32、uishers, or for liquefied petroleum gas (LPG).NOTE 2 Quick-release cylinder valves of refillable propellant gas cylinders used as part of portable fire extinguishers are also covered by this International Standard, if these cylinders are transported separately.2 Normative referencesThe following doc
