ÖNORM EN ISO 10297

This document 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 bundles of cylinders; c) cylinder valves or main valves with integrated pressure regulator (VIPR); d) valves for pressure drums and tubes; which convey compressed, liquefied or dissolved gases. This document does not apply to - valves for cryogenic equipment, portable fire extinguishers and liquefied petroleum gas (LPG); - quick-release cylinder valves (e.g. for fire-extinguishing, explosion protection and rescue applications) - requirements for quick-release cylinder valves are specified in ISO 17871 which contains normative references to this document; - self-closing cylinder valves and ball valves. This document only covers the function of a valve as a closure. Other functions that are possibly integrated in the valve can be covered by other standards. Such standards do however not constitute requirements according to this document.
