FprEN ISO 17871
(Main)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]).

Dieses Dokument behandelt die Funktion eines Schnellöffnungs-Flaschenventils als Verschlusseinrichtung.
Dieses Dokument gilt nicht für Schnellöffnungs-Flaschenventile für Kryo-Ausrüstung und für Flüssiggas (LPG).
Dieses Dokument gilt nicht für Schnellöffnungs-Flaschenventile, wenn diese als Hauptverschlusseinrichtung für tragbare Feuerlöscher verwendet werden, weil tragbare Feuerlöscher nicht von Transportvorschriften behandelt werden.
Schnellöffnungs-Flaschenventile von als Zusatz dienenden nachfüllbaren Treibgasflaschen, die in oder als Teil von tragbaren Feuerlöschern verwendet werden, sind von diesem Dokument abgedeckt, sofern sie getrennt transportiert werden, z. B. für das Befüllen (siehe Literaturhinweis [1], Kapitel 3.3, „Special Provision 225“, zweite Anmerkung).
Bouteilles à gaz - Robinets de bouteilles à ouverture rapide - Spécifications et essais de type (ISO/FDIS 17871:2020)
Le présent document, conjointement avec les normes ISO 10297 et ISO 14246, spécifie des exigences relatives à la conception, aux essais de type, au marquage, ainsi qu'aux essais de fabrication et contrôles, pour les robinets de bouteilles à ouverture rapide destinés à être montés sur des bouteilles à gaz transportables et rechargeables, des fûts à pression et des tubes qui sont conçus pour transporter des gaz liquéfiés ou comprimés:
— non toxiques;
— non oxydants;
— ininflammables; et
— non corrosifs;
ou encore des agents d'extinction chargés avec des gaz comprimés, qui sont destinés à être utilisés pour des applications d'extinction d'incendie, de protection contre les explosions ou de secours.
NOTE 1 Les applications principales de ces robinets de bouteilles à ouverture rapide sont liées à l'industrie de la lutte contre l'incendie. Il existe toutefois d'autres applications telles que les sacs gonflables anti-ensevelissement lors d'une avalanche, le gonflage de canots de sauvetage et d'autres applications similaires.
NOTE 2 Lorsqu'il n'y a pas de risque d'ambiguïté, le terme « bouteilles » est utilisé collectivement dans le présent document pour désigner les bouteilles à gaz, les fûts à pression et les tubes.
Le présent document couvre la fonction d'un robinet de bouteille à ouverture rapide en tant que dispositif de fermeture.
Le présent document ne s'applique pas aux robinets de bouteilles à ouverture rapide utilisés sur des équipements cryogéniques ou avec du gaz de pétrole liquéfié (GPL).
Le présent document ne s'applique pas aux robinets de bouteilles à ouverture rapide s'ils sont utilisés comme fermeture principale sur des extincteurs d'incendie portatifs, car ces derniers ne sont pas couverts par la réglementation sur le transport.
Les robinets de bouteilles à ouverture rapide montés sur des bouteilles rechargeables auxiliaires transportant du gaz propulseur faisant partie d'extincteurs d'incendie portatifs ou intégrés à ces derniers relèvent du présent document si lesdites bouteilles sont transportées séparément, par exemple pour le remplissage (voir le Règlement type de l'ONU, chapitre 3.3, Disposition spéciale 225, seconde note[1]).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).Any trade name used in this document is information given for the convenience of users and does not

Introduction
This document covers the function of a quick-release cylinder valve as a closure (defined by the UN
Model Regulations). 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 document has been written to be in conformity with 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
regulation always takes precedenceIn this document, 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
5 5 2(1 bar = 10 Pa = 10 N/m ).
Pressure values given in this document are given as gauge pressure (pressure exceeding atmospheric
pressure) unless noted otherwise.Charging of agents with a compressed gas is in some areas, e.g. fire-fighting, referred to as super-
pressurization.© ISO 2019 – All rights reserved v
