Low resistance shower hoses for sanitary tapware
This European Standard specifies :
- the dimensional, leaktightness, mechanical and hydraulic characteristics with which shower hoses shall comply ;
- the procedures for testing these characteristics.
It applies to shower hoses of any material used for ablutionary purposes and intended for connecting shower handsets to the sanitary tapware of baths and showers. They should only be connected downstream of the obturator of the tapware.
Details of pressure and temperature are given in Table 1.

Hoses which are an integral part of sanitary tapware (e.g. sink mixers) or hoses intended to connect sanitary tapware to the water supplies are not covered by this standard.
Brauseschläuche für Sanitärarmaturen mit geringem Durchflusswiderstand
Diese Europäische Norm legt Folgendes fest:
- die Maße, die Anforderungen an die Dichtheit, die mechanischen und hydraulischen Anforderungen, denen Brauseschläuche entsprechen müssen,
- die Prüfverfahren, um diese Anforderungen zu überprüfen.
Sie gilt unabhängig vom verwendeten Material für Brauseschläuche zur Verbindung von Handbrausen für die Körperhygiene als Ausrüstung von Sanitärarmaturen in Bädern und Duschen. Sie sollten nur hinter dem Absperrorgan der Sanitärarmatur angeschlossen werden.
Druck- und Temperaturangaben sind in Tabelle 1 enthalten.

Flexibles de douches basse pression pour robinetterie sanitaire
La présente Norme européenne spécifie :
¾ les caractéristiques dimensionnelles, d'étanchéité, de comportement mécanique et hydraulique auxquelles doivent répondre les flexibles de douches ;
¾ les modes opératoires d'essai permettant de contrôler ces caractéristiques.
Elle s'applique aux flexibles de douches, quel que soit le matériau utilisé, destinés à raccorder les douchettes aux robinetteries sanitaires de baignoires ou de douches réservées pour l'hygiène corporelle. Il convient qu'ils ne soient raccordés qu'en aval de l'obturateur de la robinetterie.
Les exigences relatives à la pression et à la température sont données dans le Tableau 1.
