Hose fittings with clamp units - Part 8: Symmetrical half coupling (Guillemin system)

This document applies to hose fittings with symmetrical half couplings (Guillemin system), with mobile locking ring, for hose assemblies with a maximum working pressure of up to 25 bar, with hose tails according to EN 14420-2 and clamp units according to EN 14420-3. Couplings in accordance with this document serve as link between hoses and connections to transport liquids, solids (e.g. powders, granules) except steam and liquid gas. It specifies dimensions, types of connections, quality of materials, marking requirements and testing requirements. The working temperature range is 20 °C up to + 65 °C.

Schlaucharmaturen mit Klemmfassungen - Teil 8: Symmetrische Kupplungen (System Guillemin)

Diese Europäische Norm gilt für Schlaucharmaturen mit symmetrischen Kupplungen (System Guillemin), mit beweglichem Klemmring für Schlauchleitungen mit einem maximalen Arbeitsdruck bis !16"bar, mit Schlauchstutzen nach EN 14420-2 und Klemmfassungen nach EN 14420-3. Kupplungen nach dieser Europäischen Norm dienen der Verbindung von Schläuchen mit Anschlüssen zum Fördern von Flüssigkeiten und Feststoffen (z. B. Pulver, Granalien), ausgenommen Dampf und Flüssiggas. Die Norm legt Maße, Anschlussarten, Werkstoffsorten, Anforderungen an die Kennzeichnung und Prüfung fest. Die Arbeitstemperatur beträgt
20 °C bis + 65 °C.

Raccords pour flexibles avec demi-coquille - Partie 8 : Demi raccords symétriques (systeme Guillemin)

Le présent document s'applique aux demi raccords symétriques (système Guillemin) à verrou mobile pour des flexibles destinés à être utilisés à une pression de service maximale de 25 bar, munis de douilles conformes à l'EN 14420 2 et de demi-coquilles conformes à l'EN 14420 3. Les accouplements conformes à la  présente norme européenne sont utilisés pour relier les tuyauteries flexibles et  les raccordements destinés au transport de liquides, de matières solides (par exemple des matières pulvérulentes ou granulaires) à l'exception des gaz liquéfiés et de la vapeur. Le présent document prescrit les dimensions, les types de raccordements, la qualité des matériaux ainsi que les exigences de marquage et d'essai. La plage de température de service est de -20 °C à + 65 °C.
