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

This European Standard specifies the design, materials, dimensions and marking requirements 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 16 bar working pressure (for aluminium-cast-materials -0,8 bar to 10 bar) in a working temperature range of -20 °C up to +65 °C.

Schlaucharmaturen mit Klemmfassungen - Teil 7: Hebelarmkupplungen

Diese Europäische Norm legt die Konstruktion, Werkstoffe, Maße und Anforderungen zur Kennzeichnung 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 (für Aluminium-Guss-Werkstoffe –0,8 bar bis 10 bar) in einem Arbeitstemperaturbereich von –20 °C bis 65 °C verwendet werden können.

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

La présente Norme européenne spécifie la conception, les matériaux, les dimensions et le marquage des raccords à cames destinés à relier les tuyaux et les connexions pour le transport de liquides, de matières solides et de gaz, à l'exception des gaz liquéfiés et de la vapeur. Les raccords sont utilisables dans une plage de pression de service de 0,8 bar ) à 16 bar (pour les matériaux en fonte d’aluminium  0,8 bar à 10 bar) pour des températures de service de 20 °C à + 65 °C.

Cevni fitingi z objemkami - 7. del: Spojke z vzvodno ročico

Ta evropski standard določa načrtovanje, materiale, dimenzije in zahteve za označevanje za spojke z vzvodno ročico, ki povezujejo cevi in priključke za prevoz tekočin, trdnih snovi in plinov, razen tekočega plina in pare. Spojke opravljajo svojo nalogo pri delovnem tlaku od −0,8 bara1) do 16 barov (za materiale iz litega aluminija od −0,8 bara do 10 barov) pri delovni temperaturi od −20 °C do +65 °C.
