CEN/TC 181/WG 8 - Pressure regulators and changeover devices

This European standard defines the constructional and operational characteristics, the safety requirements and test methods, and the marking of automatic change over devices with a capacity of less than or equal to 100 kg/h and having a maximum regulated pressure of less than or equal to 4 bar for butane, propane or their mixtures only in the vapour phase.
NOTE 1 bar = 105 Pa
Liquefied gases containing methylacetylene and propadiene are not covered by this standard. This European standard also covers safety devices likely to be fitted onto automatic change over devices. The characteristics of these devices are given in
annex A.

This standard defines the constructional and operational characteristics, the safety requirements and test methods, 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.
NOTE 1 bar = 105 Pa
This European standard also applies to the safety devices which are included within regulators covered by this standard. The characteristics of these devices are given in annexes A and B.

This European Standard defines the constructional and operational characteristics, the safety requirements and test methods, and the marking of automatic change over devices with a capacity of less than or equal to 100 kg/h and having a maximum regulated pressure of less than or equal to 4 bar for butane, propane or their mixtures only in the vapour phase.
NOTE   1 bar = 105 Pa.
Liquefied gases containing methylacetylene and propadiene are not covered by this standard.
This European Standard also covers safety devices likely to be fitted onto automatic change over devices. The characteristics of these devices are given in annex A.
The requirements of this European Standard generally cover designs where regulation is in one stage, using a single diaphragm. These requirements do not exclude designs using more than one diaphragm, provided that these diaphragms are integrated in a single automatic change over devices complying with the requirements of this European Standard.
For specific uses in caravans and leisure vehicles, the automatic change over devices function may also be carried out by an assembly of regulators, forming a "automatic change over devices system" as defined in 3.1.2. This standard covers such an assembly as follows:
-   special requirements for the manufacture, adjustment and operation of regulators forming a automatic change over devices system, as well as the corresponding test methods are given in annex B;
-   except for these special requirements, and unless otherwise stated, constructional and performance characteristics given in the body of the standard are also applicable to the devices in annex B.
The requirements apply generally to automatic change over device used in locations where the temperature likely to be reached during use is between -20 °C and +50 °C. When the devices are used at temperatures outside this range they shall comply with special requirements defined in annex C.
This standard does not include the installation rules

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.
NOTE   1 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.

This European standard defines the structural and operational characteristics, the safety requirements and test methods, the marking, of low-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 directly 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 for specific purposes (caravans and motor caravans) which are subjected to special
require-ments are dealt with in annex D.
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.
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.
