Pressure regulators, automatic change-over devices, having a maximum regulated pressure of 4 bar, with a maximum capacity of 150 kg/h, associated safety devices and adaptors for butane, propane, and their mixtures Ingestion-build-224916 then safe working at height1 Scope This European Standard defines the constructional and operational characteristics, the safety requirements, test methods and the marking of regulators and automatic change over devices having a maximum regulated pressure of 4 bar, with a maximum capacity of 150 kg h, for use with butane, propane and their mixtures in the vapour phase. This European Standard also applies to the safety devices which are included within regulating devices covered
