Full title and description

ISO 10297:2024 — Gas cylinders — Cylinder valves — Specification and type testing. This International Standard specifies design, type testing and marking requirements for cylinder valves (including certain valves with integrated pressure regulators and valves for pressure drums and tubes) used with refillable transportable gas cylinders conveying compressed, liquefied or dissolved gases.

Abstract

This document defines requirements for the design, type testing and marking of cylinder valves and main valves (excluding ball valves) for bundles, including certain valves with integrated pressure regulators (VIPR types B and C) and valves for pressure drums and tubes. It states exclusions (for example valves for cryogenic equipment, portable fire extinguishers, LPG valves, quick‑release valves and ball valves) and references other standards for specific functions or additional requirements (e.g., VIPRs, residual pressure devices, manufacturing tests).

Scope

Applies to cylinder valves intended to be fitted to refillable transportable gas cylinders, main valves (excluding ball valves) for cylinder bundles, certain valves with integrated pressure regulators (VIPR types B and C), and valves for pressure drums and tubes used to convey compressed, liquefied or dissolved gases. The standard covers valve function as a closure (design, type testing and marking) but does not cover cryogenic equipment valves, LPG valves, quick‑release valves, self‑closing valves or ball valves; these are covered by other ISO or regional standards.

Key topics and requirements

• Design requirements for cylinder and main valves intended for transportable gas cylinders.
• Type testing procedures (mechanical, pressure and functional tests) required to demonstrate conformity with performance requirements.
• Marking and identification requirements for valves (manufacturer identification, flow direction, pressure ratings, and relevant markings).
• Specific provisions and definitions for valves with integrated pressure regulators (VIPR), including VIPR types B and C and their particular design considerations.
• Explicit exclusions and cross‑references to other standards for specialised valve functions (e.g., cryogenic valves, LPG, quick‑release, ball valves) and for manufacturing tests.

Typical use and users

Used by cylinder and valve manufacturers, component designers, testing and certification bodies, regulatory authorities, gas suppliers and distributors, inspection and maintenance organizations, and safety engineers involved in the specification, testing and certification of valves for transportable gas cylinders and associated equipment.

FAQ

Q: What is this standard?

A: ISO 10297:2024 is an International Standard that specifies design, type testing and marking requirements for cylinder valves and certain main valves used on transportable gas cylinders.

Q: What does it cover?

A: It covers valve function as a closure — design criteria, required type tests (mechanical and pressure tests), marking and identification. It includes provisions for valves with integrated pressure regulators (VIPRs) of specified types and lists explicit exclusions that are addressed by other standards.

Q: Who typically uses it?

A: Manufacturers of cylinders and valves, testing laboratories and certification bodies, gas suppliers and distributors, regulatory and inspection authorities, and engineers responsible for specifying and testing cylinder valves.

Q: Is it current or superseded?

A: ISO 10297:2024 is the current edition (Edition 4) published on 1 April 2024 with a corrected version issued May 2024; it replaces earlier editions (including ISO 10297:2014).

Q: Is it part of a series?

A: It is part of a family of standards addressing valves, pressure‑reducing devices and cylinder equipment; related ISO standards define additional or specialized requirements (VIPRs, residual pressure devices, cryogenic valves, LPG valves and manufacturing tests).

Q: What are the key keywords?

A: Cylinder valve, gas cylinder, valve specification, type testing, VIPR, pressure regulator, marking, transportable gas cylinder.
