Introduction
Gas cylinders are usually fitted with a valve to contain the gas or allow its discharge.
Requirements for the specification and type testing of cylinder valves are given in EN 849.
1 Scope

This Standard is applicable to valves to be fitted to industrial and medical gas cylinders, up to 150 l
water capacity, intended to convey compressed, liquefied or dissolved gases.
This Standard is only applicable to valves operated by a hand wheel or a key.
This Standard is not applicable to valves for breathing equipment, fire extinguishers, cryogenic
equipment and liquefied petroleum gas (LPG).
