European Norm



This document specifies 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.

The maximum supply pressures for devices covered by this standard are 7,5 bar for butane and 16 bar for propane and LPG.

This document also applies to the safety devices which are included within regulating devices covered by this document.

This document also includes requirements for:
— adaptors for connecting to self-closing valves;
— integral or auxiliary safety devices.

This document covers devices used in locations where the temperature likely to be reached during use is between −20 °C and +50 °C

Additional requirements for devices to be used at temperatures down to −30 °C and/or up to +80 °C are defined in Annex C.

This document gives special requirements for:
— devices intended to be used in caravans and motor caravans (Annex D);
— devices intended to be used in boats (Annex M);
— specific connections which are not defined in other standards (e.g. EN 15202:2012 for cylinder valve

NOTE: Boats considered in this document are recreational crafts covered by European Directive 2013/53/EU.
