Overview

This European Standard defines the constructional and operational characteristics, the safety requirements, test methods and the marking of pressure regulators and automatic change-over devices having a maximum regulated pressure of up to and including 4 bar, with a capacity of up to and including 150 kg/h, for use with butane, propane and their mixtures in the vapour phase. This European Standard also applies to safety devices which are integrated in regulating devices covered by this standard. The characteristics of these safety devices are given in Annexes A and B. This standard also includes the requirements for: - adaptors for connecting to self-valves; - independent supply-reserve indicators; - independent safety devices. For the purpose of this standard: - pressure regulators and automatic change-over devices are referred to as "regulating devices"; - pressure regulators, automatic change-over devices and adaptors are referred to as "devices". The requirements generally 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 pressure regulating devices intended to be used in caravans, motor caravans and freshwater boats are given in Annex D. Additional requirements for pressure regulating devices intended to be used in seawater boats are given in Annex M. For specific use in caravans, motor caravans and boats (freshwater and seawater), the automatic change-over device function may also be carried out by an assembly of pressure regulators, forming an automatic change-over device system as defined in 3.1.2. This European Standard does not include installation instructions for devices and their associated safety devices. For this purpose, reference should be made to national regulations in force in the member countries. All connections and their use in different countries are given in Annexes G and H. - Drawings of cylinder valve connections are presented in EN 15202; - Drawings of gas cartridges are presented in EN 417; - Drawings of other connections are presented in Annexes G and H, although the part of the device is normative. The other part refers to the part to which the device is connected, is merely represented for test purposes and is not normative.
