Hose fittings with clamp units - Part 1: Requirements, survey, designation and testing
This document specifies requirements for hose fittings with clamp units for hoses made of rubber/plastics or thermoplastics preferably for use with flammable and non flammable products. It contains requirements for hose fittings to ensure that, when used appropriately, the user or third persons are not exposed to hazards from fire, explosions or acid burns, for example from mineral oils or chemicals, and that the environment is protected from pollution and other detriments. The use of non-asbestos materials for gaskets in hose fittings is recommended in this series of standards.
For maximum working pressure (WP) and temperature see 3.3.
Schlaucharmaturen mit Klemmfassungen - Teil 1: Anforderungen, Übersicht, Bezeichnung und Prüfung
Diese Europäische Norm legt die Anforderungen für Schlaucharmaturen mit Klemmfassungen für Schläuche aus Gummi/Kunststoff oder Thermoplast fest, die vorzugsweise für brennbare und nichtbrennbare Produkte verwendet werden. Sie enthält Anforderungen an Schlaucharmaturen, um sicherzustellen, dass bei bestimmungsgemäßem Gebrauch Benutzer oder Dritte keinen Gefahren durch Brand, Explosionen oder Verätzungen zum Beispiel durch Mineralöle oder Chemikalien ausgesetzt sind und die Umwelt vor Verunreinigungen und Beeinträchtigungen geschützt ist. In dieser Normenreihe wird für Dichtungen in Schlaucharmaturen die Verwendung asbestfreier Werkstoffe empfohlen.
Maximale Arbeitsdrücke und -temperaturen siehe 3.3.
