This document specifies the requirements for the design, testing and marking of spring-loaded pressure relief valves (PRVs) for use with liquefied petroleum gas (LPG) cylinders with a water capacity of 0.5 litres up to 150 litres inclusive. These PRVs may be an integral part of the cylinder valve (see EN ISO 14245 [4] and EN ISO 15995 [5]) or a separate device.
