LPG equipment and accessories - Essential operational dimensions for LPG cylinder valve outlet and associated equipment connections

This European Standard specifies basic dimensions of cylinder valves (manufactured in accordance with EN 13152 and EN 13153) and connectors (including regulators) to enable them to be connected together.
This European Standard lists connections where it may be possible to connect together, but which when connected may not be sound or secure in some operating conditions or orientations.
This European Standard also recommends tightening torques for the attachment of screwed metal-to-metal connections.
This European Standard contains the drawings, which describe direct cylinder valve connections in the following standards:
-   EN 12864,
-   EN 13785, and
-   EN 13786.
Quality assurance systems, production testing and particularly certificates of conformity are not covered in this standard.
This European Standard excludes connections for automotive vehicles covered by UN/ECE Regulation 67 and EN 13760 and excludes connections for cartridges.

Diese Europäische Norm enthält ebenfalls Empfehlungen zu Anschlussdrehmomenten für das Anbringen von Schraubverbindungen von Metall auf Metall.
Diese Europäische Norms Dokument enthält die Darstellungen, die direkte Flaschenventil-Verbindungen beschreiben, entsprechend:
-   EN 12864;
-   prEN 13785; und
-   EN 13786.
Qualitätssicherungssysteme, Fertigungsprüfung und besondere Konformitätsnachweise werden in diesem Dokument nicht behandelt.
Diese Europäische Norm gilt nicht für Verbindungen von Autogasfahrzeugen, die in UN/ECE Regulation 67 und EN 13760 geregelt sind und nicht für Anschlüsse von Kartuschen.

Equipements pour GPL et leurs accessoires - Dimensions opérationnelles essentielles des connexions des robinets et valves de bouteilles de GPL et des équipements associés

La présente Norme européenne spécifie les dimensions de base des robinets et valves de bouteilles (fabriqués conformément a l’EN 13152 et a l’EN 13153) et des matériels qui s’y connectent (y compris les détendeurs) afin de permettre leur raccordement.
La présente Norme européenne fournit la liste des connexions qu’il est possible de raccorder ensemble mais qui, une fois le raccordement effectué, sont susceptibles de ne plus etre saines ou sures dans certaines conditions d’utilisation ou d’orientation.
La présente Norme européenne recommande également des couples de serrage pour le montage des connexions métal/métal vissées.
La présente Norme européenne comporte les schémas qui décrivent les connexions directes des robinets et des valves de bouteilles dans les normes suivantes :
   l’EN 12864 ;
   l’EN 13785 ; et
   l’EN 13786.
La présente norme ne traite pas des systemes d’assurance qualité, des essais production, notamment des certificats de conformité.
La présente Norme européenne exclut les connexions des véhicules automobiles traités dans le Reglement 67 UN/ECE et dans l’EN 13760 ainsi que les connexions des cartouches
