This document specifies the design, testing and marking requirements for spring loaded pressure relief valves (PRV), for use in liquefied petroleum gas (LPG) cylinders of water capacity of 0,5 l up to and including 150 l.<\/p>\n

These PRVs can be either an integral part of a cylinder valve (see EN ISO 14245<\/span><\/span> [4] and EN ISO 15995<\/span><\/span> [5]) or a separate device.<\/p>\n
