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.

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,
