Overview
EN ISO 17871:2020 (ISO 17871:2020) specifies requirements for quick-release cylinder valves used as closures on refillable, transportable gas cylinders, pressure drums and tubes. It covers valves for non-toxic, non-oxidizing, non-flammable and non-corrosive compressed or liquefied gases and for extinguishing agents charged with compressed gas - primarily used in the fire‑fighting industry but also in avalanche airbags, life‑raft inflation and similar applications. The standard focuses on valve design, type testing, marking, manufacturing tests and examinations.
Key topics and technical requirements
- Design and function: Requirements for valve operating mechanisms (pistons, flaps, piercing or differential pressure devices) and valve operating devices for quick release of cylinder contents.
- Valve types: Defines one‑time (type A) and multiple‑operation valves (types B–E) with differing cycle limits and maintenance needs.
- Type testing and safety: Tests for mechanical strength, resistance to impact, endurance, leak tightness, and provisions for valve burst test pressure (new to this edition).
- Manufacturing tests and examinations: Production-level inspections and tests to verify conformity with the specification (see Annex A).
- Marking and documentation: Mandatory marking and documentation to support traceability, safe use and regulatory compliance.
- Scope boundaries: Does not apply to quick‑release valves for cryogenic equipment or LPG, nor to valves used as the main closure of portable fire extinguishers (except auxiliary refillable propellant cylinders transported separately).
- Regulatory alignment: Written to be referenced in the UN Model Regulations; harmonizes with ISO 10297 and ISO 14246.

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) can be covered by
other standards and/or regulations.
Quick-release cylinder valves complying with this document can be expected to perform satisfactorily
under normal service conditions.
This document pays particular attention to:
a) suitability of materials;
b) safety (mechanical strength, impact strength, endurance, leak tightness);
c) testing;
d) marking.
[1]
This document has been written so that it is suitable to be referenced in the UN Model Regulations .
In 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.
INTERNATIONAL STANDARD ISO 17871:2020(E)

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,

The article discusses EN ISO 17871:2020, a specification for quick-release cylinder valves used in various industries. The valves are designed to be fitted to gas cylinders, pressure drums, and tubes that carry non-toxic, non-oxidizing, non-flammable, and non-corrosive compressed or liquefied gases or extinguishing agents. The document covers design, testing, marking, and manufacturing requirements for these valves. It notes that the valves are primarily used in the fire-fighting industry but also have applications in other areas such as avalanche airbags and life raft inflation. The specification does not apply to quick-release cylinder valves for cryogenic equipment or liquefied petroleum gas (LPG). Additionally, it does not cover valves used as the main closure of portable fire extinguishers, as those are not regulated by transport rules. However, it does include valves for auxiliary refillable propellant gas cylinders used within or as part of portable fire extinguishers, if those cylinders are transported separately for filling.
이 기사는 EN ISO 17871:2020에 대해 논의하고 있는데, 이는 다양한 산업에서 사용되는 퀵 리리스 실린더 밸브에 대한 명세입니다. 이 밸브는 비독성, 비산화, 비가연 및 비부식성 압축 또는 액화된 가스 또는 소화제를 운반하는 가스 실린더, 압력 드럼 및 관에 장착될 수 있도록 설계되었습니다. 이 문서는 이러한 밸브에 대한 설계, 시험, 표시 및 제조 요구사항을 다루고 있습니다. 이는 이러한 밸브가 주로 소방 산업에서 사용되지만, 산사태 에어백이나 라이프래프트 팽창과 같은 다른 분야에도 응용될 수 있다는 것을 언급합니다. 이 명세서는 크리오젠 장비나 액화 석유 가스 (LPG)용 퀵 리리스 실린더 밸브에는 적용되지 않습니다. 또한, 휴대용 소화기의 주요 폐쇄장치로 사용되는 퀵 리리스 실린더 밸브에는 적용되지 않으며, 이는 운송 규정에서 규정되지 않기 때문입니다. 그러나 이 명세서에는 휴대용 소화기의 일부로 사용되거나 독립적으로 운반되는 보조 충전식 추진 가스 실린더에 대한 밸브도 포함되어 있습니다(UN 모델 규정, 제3.3장, 특수 규정 225, 두 번째 주석 참조).
この記事はEN ISO 17871: 2020を取り上げており、さまざまな産業で使用されるクイックリリースシリンダーバルブに関する仕様について議論しています。このバルブは、無毒で酸化しない、可燃性ではない、腐食しない圧縮または液化ガスまたは消火剤を運ぶガスシリンダー、圧力ドラム、および管に取り付けるために設計されています。この文書は、これらのバルブの設計、試験、マーキング、および製造の要件をカバーしています。バルブは主に消防産業で使用されることがメインですが、雪崩エアバッグやライフラフトの膨張など、他の用途にも使用されることもあります。この仕様書は、クライオジェニック装置や液化石油ガス（LPG）用のクイックリリースシリンダーバルブには適用されません。また、携帯用消火器の主な閉塞装置として使用されるクイックリリースシリンダーバルブにも適用されません。なぜなら、携帯用消火器は輸送規則の対象外であるためです。ただし、充填のために別々に輸送される場合、携行式消火器の一部または一部として使用される補助的な充填可能推進ガスシリンダーのクイックリリースシリンダーバルブは、この文書の対象となります（UNモデル規則、第3.3章、特別規定225、第2注を参照）。
