Additional features of a quick-release cylinder valve (e.g. pressure reg

29、ulators, 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 with the UN Model Regulations. When published, it will be submitted to the UN Subcomm

30、ittee 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 regulation always takes precedenceIn this International Standard, the unit bar is use

31、d 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 International Standard are given as gauge pressure (pressure exceeding atmospheri

32、c pressure) unless noted otherwise.EN ISO 17871:2015 (E) 5DIN EN ISO 17871:2015-12 1 ScopeThis International Standard 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

33、 intended to be fitted to refillable transportable gas cylinders which convey non-toxic, non-oxidizing, 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 ma

34、in 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.This International Standard covers the function of a quick-release cylinder valve as a closure.This

35、 International Standard does not apply to quick-release cylinder valves for cryogenic equipment, for portable fire extinguishers, 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 cove

36、red by this International Standard, if these cylinders are transported separately.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
