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.
