Hose fittings with clamp units - Part 6: TW tank truck couplings

This document specifies the design, materials and dimensions for hose fittings with couplings for tank trucks (TW couplings).
Couplings for tank trucks in accordance to this document are intended to link hoses with connections for the transport of liquids, solid matters and gases with the exception of liquid gas and steam. They can be employed in a working pressure range of - 800 mbar up to 25 bar at working temperatures of - 20 °C up to + 65 °C. Couplings for tank trucks for other operating conditions is subject to agreement.
WARNING   Male and female dust couplings are pressure resistant plugs. They do not work as locking device, so, if pipelines remain under pressure, a locking device shall be superposed.

Schlaucharmaturen mit Klemmfassungen - Teil 6: TW Tankwagen-Kupplungen

Diese Europäische Norm legt die Konstruktion, Werkstoffe und Maße für Schlaucharmaturen mit Kupplungen für Tankwagen (TW-Kupplungen) fest.
Kupplungen für Tankwagen nach dieser Norm dienen der Verbindung von Schläuchen mit Anschlüssen zum Fördern von Flüssigkeiten, Feststoffen und Gasen, ausgenommen Flüssiggas und Dampf. Die Kupplungen können in einem Arbeitsdruckbereich von - 800 mbar bis 25 bar bei Arbeitstemperaturen von - 20 °C bis + 65 °C verwendet werden. Tankwagen-Kupplungen für andere Betriebsbedingungen müssen vereinbart werden.
WARNUNG - Vater- und Mutterteil-Blindkupplungen sind druckbeständige Verschlüsse. Sie übernehmen jedoch nicht die Funktion eines Absperrorgans, das in jedem Fall vorgeschaltet sein muss, solange Leitungen unter Druck stehen.
