本欧洲标准规定了减压阀隔离装置、阀组、排气管和系统总成的设计、试验和检验要求，必要时，与液化石油气（LPG）用静压容器用减压阀一起使用。本欧洲标准涉及隔离装置和PRV阀组的原型试验和生产试验。液化石油气压力容器的泄压阀见EN 14129:2014。

This European Standard specifies the design, testing and inspection requirements for pressure relief valve isolating devices, valve manifolds, vent pipes and system assemblies which are, where necessary, used with pressure relief valves for use in static pressure vessels for Liquefied Petroleum Gas (LPG) service. This European Standard addresses both prototype testing and production testing of isolating devices and PRV manifolds. Pressure relief valves for LPG pressure vessels are specified in EN 14129:2014.
