This document 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 document also applies to the safety devices which are included within regulating devices covered by this standard. The characteristics of these safety devices are given in Annexes A and B. This document also includes the requirements for: - adaptors for connecting to self-closing valves; - auxiliary safety devices. For the purpose of this European Standard: - regulators and automatic change-over devices are referred to as “regulating devices”; - regulators, automatic change-over devices and adaptors are referred to as “devices”. This document does not cover automatic change over devices which do not have a regulating function. The requirements apply to 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 below -20 °C are given in Annex C. Additional requirements for regulating devices intended to be used in caravans, motor caravans and freshwater boats are given in Annex D. Additional requirements for regulating devices intended to be used in seawater boats are given in Annex M. All connections and the countries in which they are used are given in Annexes G and H. This document defines only specific connections which are not defined in other standards (e.g. EN 15202:2012 for cylinder valve connections). This document covers: - Regulating devices fitted with an over-pressure relief valve of a limited flow rate (PRV) (see A.1) - Regulating devices fitted with an over-pressure shut off safety device (OPSO) (see A.2) - Regulating devices fitted with a regulated outlet pressure limiter (see A.5) - Two stage pressure limiting regulating device (see A.6) which are considered as “safety accessories” and all other devices which are considered as “pressure accessories” according to the Pressure Equipment Directive (2014/68/EU). Gas pressure regulators according to this document do not have their own source of ignition and therefore are not within the scope of European Directive 2014/34/EU. Any additional component (e.g. proximity switch, travel transducer etc.) should be independently considered in the framework of assemblies as per ATEX Guideline “Guideline on the application of Council directive 94/9/EC of 23rd March 1994 edition June 2009”, Clauses 3.7.3 and 3.7.4.
