Description of BS EN ISO 10297:2014+A1:2017 2017

This International Standard specifies design, type testing and marking requirements for:

1. cylinder valves intended to be fitted to refillable transportable gas cylinders;

2. main valves (excluding ball valves) for cylinder bundles;

3. cylinder valves or main valves with integrated pressure regulator (VIPR);

4. valves for pressure drums and tubes;

which convey compressed, liquefied or dissolved gases.

NOTE 1 Where there is no risk of ambiguity, cylinder valves, main valves, VIPR and valves for pressure drums and tubes are addressed with the collective term “valves” within this document.

This International Standard covers the function of a valve as a closure.

This International Standard does not apply to

• valves for cryogenic equipment, portable fire extinguishers and liquefied petroleum gas (LPG), and

• quick-release cylinder valves (e.g. for fire-extinguishing, explosion protection and rescue applications), self-closing cylinder valves or ball valves.

NOTE 2 Requirements for valves for cryogenic vessels are specified in ISO 21011 and at a regional level, e.g. in EN 1626. Requirements for LPG valves are specified in ISO 14245 or ISO 15995. Requirements for quick-release cylinder valves are specified in ISO 17871. Requirements for self-closing cylinder valves are specified. in ISO 17879. Requirements for valves for portable fire extinguishers at a regional level are specified e.g. in EN 3 series.

NOTE 3 Requirements for manufacturing tests and examinations of valves covered by this International Standard are given in ISO 14246.

NOTE 4 Additional requirements for VIPR are specified in ISO 22435 for industrial applications or ISO 10524‑3 for medical applications. Additional requirements for residual pressure valves with or without a non-return function are specified in ISO 15996. Additional requirements for pressure-relief devices might be specified in international/regional regulations/standards.

NOTE 5 Additional specific requirements for valves for breathing apparatus at a regional level are specified e.g. in EN 144 series. Additional specific requirements for quick-release valves for fixed fire-fighting systems are specified in ISO 16003 and at a regional level e.g. in EN 12094‑4.
