ISO 17871:2020/Amd 2 is an ISO amendment to the standard for gas cylinders quick-release cylinder valves. It updates the specification and type-testing text for valves used as closures, and it is meant for manufacturers, test laboratories, and anyone specifying or checking these valves.

What does ISO 17871:2020/Amd 2 specify?

ISO 17871:2020/Amd 2 specifies targeted changes to the base standard for quick-release cylinder valves. The amendment narrows the scope to the valve’s closure function and updates several testing, leakage, and marking provisions.

The amendment is organized by direct replacements to the Scope, Clause 2, Clause 4, Clause 5, and Annex A. It also updates cross-references to companion standards used for valve testing and related requirements.

A key scope note states that additional valve functions can be covered by other standards, but those other standards are not requirements of ISO 17871 itself. The note also points to extra requirements for quick-release cylinder valves for fixed fire-fighting systems and for residual pressure valves (RPVs).

What are the key requirements of ISO 17871:2020/Amd 2?

ISO 17871:2020/Amd 2 mainly adjusts which companion standards apply, which tests are required, and how valves are marked. In practice, it changes how a manufacturer demonstrates conformity and which test results can be waived for certain valve designs and applications.

Base conformity with related valve standards

Quick-release cylinder valves shall comply with the relevant requirements of ISO 23826, ISO 10297 or ISO 17879, as applicable, unless ISO 17871 expressly allows different requirements or adds its own. This matters because the amendment sits on top of those standards rather than replacing them.

Filling connection non-return valve requirements

Where the valve filling connection is separate from the outlet connection and includes a non-return valve, the amendment points to the current ISO 10297 requirements for that non-return valve. The manufacturer decides the number of endurance cycles for that filling connection non-return valve, so the test plan has to reflect the intended design and duty.

Leakage and tightness testing

The amendment changes several leak-tightness expectations. The total external leakage limit remains capped at 12 cm3/h where that test is used, and some internal leak-tightness checks are removed or limited to certain valve types and applications.

For example, one internal leak-tightness check at low pressure is no longer needed, another is only for valves designed for intermittent discharge, and some transport-and-storage checks are waived for quick-release cylinder valves used only in fixed fire-fighting systems in covered areas when the system minimum exposure temperature is -20 °C. For type A valves, the pre-endurance internal and external leak-tightness test is not required.

Hydraulic pressure testing

The amendment revises the hydraulic test wording and the pressure terms used. It introduces the term hydraulic pressure test and requires the manufacturer to show that the valve design can withstand the specified hydraulic pressure throughout the valve body.

For extinguishing agents charged with compressed gases, the amendment also gives a separate rule for the hydraulic valve test pressure. That matters because the pressure demonstration is part of type testing and must match the valve’s intended service.

Marking before service

Valves conforming to this document shall be permanently and legibly marked before entering service, using one of the listed permanent methods such as forging, etching, hard metal stamping, engraving, pin stamping, laser etching, or an equivalent method. Adhesive labels are excluded. The markings must be separated by at least one space, and extra marking may be required by regulations or customer needs.

What terms does ISO 17871:2020/Amd 2 define?

• Quick-release cylinder valve - The valve type covered by ISO 17871, used as a cylinder closure with quick-release operation.
• Residual pressure valve (RPV) - A valve type mentioned in the scope note as having additional requirements in ISO 15996.
• Hydraulic pressure test - The pressure test used to show that the valve body can withstand the required hydraulic load.
• Hydraulic valve test pressure (pvht) - The pressure term used in this amendment for the hydraulic test requirement.
• Normal temperature and pressure (NTP) - A condition phrase removed from Annex A.2.2 in the amendment update.

Who uses ISO 17871:2020/Amd 2?

ISO 17871:2020/Amd 2 is used by valve manufacturers, test houses, certification bodies, and quality managers who need to design, test, mark, or assess quick-release cylinder valves. It is also relevant to users of fixed fire-fighting systems and to anyone specifying valves for gas cylinders where closure performance and leak tightness matter.

What changed in ISO 17871:2020/Amd 2 from the previous edition?

ISO 17871:2020/Amd 2 is an amendment to ISO 17871:2020. It changes the scope to focus on the closure function, adds notes about ISO 16003, EN 12094-4, and ISO 15996, updates references to ISO 10297:2024 and ISO 17879:2026, revises several test and leakage clauses in Clause 4, changes the marking text in Clause 5, and updates Annex A references to ISO 17879:2026 Annex E.

Which standards are used with ISO 17871:2020/Amd 2?

• ISO 10297:2024 - Supplies current valve requirements and test references used throughout the amendment.
• ISO 17879:2026 - Provides companion requirements and tables that the amendment cross-references for applicable tests.
• ISO 23826:2021 - Acts as one of the base standards whose requirements are modified or excepted by ISO 17871.
• ISO 16003 - Gives additional requirements for quick-release cylinder valves for fixed fire-fighting systems.
• EN 12094-4 - Regional reference named for additional fixed fire-fighting system requirements.
• ISO 15996 - Gives additional requirements for residual pressure valves (RPVs).

What does the ISO 17871:2020/Amd 2 document contain?

The amendment contains replacement text for the scope, updated normative references, and revised requirements in Clauses 4 and 5. It also updates cross-references in Annex A.

It points users to the companion standards for test tables and procedures rather than repeating those details. In practice, that means the document is used to align type testing, leakage checks, hydraulic pressure demonstration, and marking with the current referenced standards.

The amendment also shows where some tests are waived or limited for specific valve types, service conditions, or fixed fire-fighting applications. That helps manufacturers and test labs decide which checks apply to a particular valve design before entering service.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux
de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents
critères d'approbation requis pour les différents types de documents ISO. Le présent document
a été rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2
