Hose fittings with clamp units - Part 7: Cam locking couplings

This document details the design, materials and dimensions for cam locking couplings that serve as the link between hoses and connections to transport liquids, solids and gases, except liquid gas and steam. The couplings are capable of operating the pressure range - 0,8 bar to 25 bar working pressure in a working temperature range of - 20 °C up to + 65 °C.
WARNING - Line pressure shall be reduced before disconnection.

Schlaucharmaturen mit Klemmfassungen - Teil 7: Hebelarmkupplungen

Diese Europäische Norm legt die Konstruktion, Werkstoffe und Maße für Hebelarmkupplungen fest, die der Verbindung von Schläuchen mit Anschlüssen zum Fördern von Flüssigkeiten, Feststoffen und Gasen, ausgenommen Flüssiggas und Dampf, dienen. Die Kupplungen müssen in einem Druckbereich von  0,8 bar bis !16"bar Arbeitsdruck in einem Arbeitstemperaturbereich von  20 °C bis + 65 °C verwendet werden können.
WARNHINWEIS  Vor dem Entkuppeln muss der Druck in der Leitung reduziert werden.

Raccords pour flexibles avec demi-coquille - Partie 7: Raccords à cames

Le présent document décrit la conception, les matériaux et les dimensions des accouplements à cames destinés à relier les tuyauteries flexibles aux raccordements de transport de liquides, de matières solides et de gaz, à l'exception des gaz liquéfiés et de la vapeur. Les accouplements sont utilisables dans une plage de pression de service de - 0,8 bar à 25 bar pour des températures de service de - 20 °C à + 65 °C.
AVERTISSEMENT - Avant déconnexion, la pression de la canalisation doit être détendue.
