ISO 10297:2014

ISO 10297:2014 specifies design, type testing and marking requirements for: a) cylinder valves intended to be fitted to refillable transportable gas cylinders; b) main valves (excluding ball valves) for cylinder bundles; c) cylinder valves or main valves with integrated pressure regulator (VIPR); which convey compressed, liquefied or dissolved gases. ISO 10297:2014 covers the function of a valve as a closure. It does not apply to valves for cryogenic equipment, portable fire extinguishers and liquefied petroleum gas (LPG) and quick-release valves (e.g. for fire-extinguishing, explosion protection and rescue applications), non-return valves or ball valves.
