(Main)Regulators with a capacity of up to and including 100 kg/h, having a maximum nominal outlet pressure of up to and including 4 bar, other than those covered by EN 12864 and their associated safety devices for butane, propane or their mixtures
Regulators with a capacity of up to and including 100 kg/h, having a maximum nominal outlet pressure of up to and including 4 bar, other than those covered by EN 12864 and their associated safety devices for butane, propane or their mixtures
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.
Druckregelgeräte mit einem höchsten Ausgansdruck von < 4 bar und einem Durchfluss < 100 kg/h, die nicht in EN 12864 geregelt sind, für Butan, Propan oder deren Gemische sowie die dazugehörigen Sicherheitseinrichtungen
Dieses Dokument legt die Bau- und Funktionseigenschaften, die sicherheitstechnischen Anforderungen, Prüfverfahren und Kennzeichnung von Druckregelgeräten mit einem Durchfluss von kleiner oder gleich 100 kg/h, außer den Druckregelgeräten nach EN 12864, für Butan, Propan und deren Gemische fest.
Druckregelgeräte für Freizeitfahrzeuge mit einem Durchfluss bis 1,5 kg/h werden in der EN 12864 geregelt.
ANMERKUNG 1 bar 105 Pa
Dieses Dokument gilt auch für Sicherheitseinrichtungen, die in Druckregelgeräten dieses Dokumentes enthalten sind. Die Besonderheiten dieser Einrichtungen sind in den Anhängen A und B aufgeführt.
Die Anforderungen gelten im Allgemeinen für Druckregelgeräte, die an Orten verwendet werden, bei denen im Betrieb Temperaturen zwischen 20 °C und 50 °C erreicht werden. Bei Anwendung der Geräte bei Temperaturen unterhalb 20 °C ist es notwendig, dass sie den im Anhang C festgelegten Anforderungen entsprechen.
Dieses Dokument enthält keine Installationsvorschriften von Druckregelgeräten. Hierbei sollten Hinweise auf die in den Mitgliedsstaaten geltenden nationalen Bestimmungen gegeben werden.
Dieses Dokument befasst sich nur mit Baumusterprüfungen.
ACHTUNG - Die Bilder in den Anhängen G und H zeigen die Anschlusstypen der Länder, in denen die Druckregelgeräte verwendet werden.
Der obere Bereich dieser Bilder (über der horizontalen Linie) gilt für die Druckregelgeräte und ist normativ.
Der untere Bereich dieser Bilder (unter der horizontalen Linie) gilt für den Teil, der mit dem Druckregelgerät verbunden wird. Dies dient als Hinweis für die Prüfungen und ist nicht normativ.
Détendeurs de débit inférieur ou égal à 100 kg/h, à pression de détente nominale maximale inférieure ou égale à 4 bar, autres que les détendeurs relevant de l'EN 12864, et leurs dispositifs de sécurité associés pour butane, propane ou leurs mélanges
La présente norme européenne a pour but de définir les caractéristiques de construction et de fonctionnement, les exigences de sécurité, les techniques d’essais et le marquage, des détendeurs d'un débit inférieur ou égal à 100 kg/h, autres que les détendeurs objets de l'EN 12864, utilisés pour le butane, le propane ou leurs mélanges, considérés uniquement à l'état gazeux.
Les détendeurs pour caravanes, jusqu’à 1,5 kg/h, sont couverts par l’EN 12864.
NOTE 1 bar = 105 Pa.
La présente norme européenne est également applicable aux dispositifs de sécurité qui sont susceptibles d'équiper les détendeurs visés par la présente norme. Les caractéristiques de ces dispositifs sont données dans les Annexes A et B.
Les spécifications de cette norme européenne s'appliquent en général aux détendeurs utilisés dans les régions où la température susceptible d'être atteinte en service varie entre – 20 °C et 50 °C. Lorsque les détendeurs sont utilisés à des températures situées au-dessous de – 20 °C, ils doivent répondre à des exigences particulières, qui sont définies dans l'Annexe C.
La présente norme ne spécifie pas les règles d'installation des détendeurs. Il y a lieu dans ce domaine de se reporter aux règles d'installation en vigueur dans les pays membres.
La présente norme couvre uniquement les essais de type.
AVERTISSEMENT — Les Figures des Annexes G et H présentent les types de raccordements retenus selon les pays d’utilisation des détendeurs.
La partie supérieure de ces Figures (au dessus du trait horizontal) s’applique au détendeur et est normative.
La partie inférieure de ces Figures (au dessous du trait horizontal) s’applique au composant destiné à être raccordé au détendeur. Celle-ci est donnée à titre indicatif pour le besoin des essais et n’est pas normative.

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. 2 Normative references The following referenced documents are indispensable for the application of this document.
