    Abstract - (Show below) - (Hide below)

    This document defines the constructional and operational characteristics, the safety requirements, test methods and the marking of regulators having a capacity of less than or equal to 100 kg/h, other than the regulators covered by EN 12864, for butane, propane or their mixtures, in the gaseous phase.Regulators for caravans up to 1,5 kg/h are covered by EN 12864.NOTE1 bar = 105 Pa.This document also applies to the safety devices which are included within regulators covered by this document. The characteristics of these devices are given in annexes A and B.The requirements apply generally to regulators used in locations where the temperature likely to be reached during use is between -20 °C and +50 °C. When the regulators are used at temperatures below -20 °C it is essential that they comply with special requirements which are defined in annex C.This document does not include the installation rules for regulators. Reference should be made to national regulations in force in the member countries.This document only covers type testing.WARNING NOTICE: The figures in annexes G and H show the types of connections used according to the country of use of the regulators.The top part of these figures (above the horizontal line) applies to the regulator and is normative.The bottom part of these figures (below the horizontal line) applies to the part to be connected to the regulator. This is given as a guide for the tests and is not normative.
