This European standard defines the structural and operational characteristics, the safety requirements and test methods, the marking, of Iow-pressure, non adjustable regulators for butane, propane or their mixtures, referred to in the body of the text as "regulators". This European Standard covers regulators supplied at vapour pressure by one or several portable cylinders. They are normally derectly connected to the cylinder valve or the self closing valve. The regulators covered by this standard are designed for a maximum outlet pressure of up to and including 200 mbar and a maximum rate of up to and including 4 kg/h. This European Standard also applies to the safety devices which are supplied as part of the regulators. The characteristics of these devices are given in annex A and B. The requirements of this European Standard apply generally to regulators used in locations where the temperature likely to be reached during use is between - 20 ~C and + 50 ~C, + 50 ~C being the maximum temperature allowable for the cylinder. When the devices are subjected to temperatures below this range, they shall comply with special requirements defined in annex C. Regulators designed to be used in caravans, motor caravans and freshwater boats which are subjected to special requirements, are dealt with in Annex D. Regulators designed to be used in seawater boats which are subjected to special requirements, are dealt with in Annex M. This European standard does not include the installation rules for regulators and their possible associated safety devices. In this matter, reference should be made to national regulations in force in the member countries. Regulators which are intended to be used with gases containing methylacetylene and propadiene are excluded from the scope of this European Standard. This European standard only covers type testing.
