Irrigation techniques - Connection and control accessories for use in irrigation systems - Technical characteristics and testing

This standard describes the technical characteristics and requirements of hydraulic connection and control accessories to ensure a sufficient mechanical resistance for practical use, and specifies the relevant testing methods. It applies to accessories made of steel, brass, aluminium, Polypropylene, Polyethylene or PVC for use in irrigation systems up to a diameter of 250 mm.

Bewässerungsverfahren - Verbindungs- und Steuerzubehör für den Einsatz in Bewässerungssystemen - Technische Eigenschaften und Prüfung

Diese Norm führt auf und legt fest die Eigenschaften von Verbindungs- und Steuerzubehör, um eine zufriedenstellende mechanische Widerstandsfähigkeit im praktischen Einsatz sicherzustellen, und spezifiziert ihre Prüfung. Sie ist anwendbar für Zubehör z. B. aus  Stahl, Buntmetall, Aluminium, Polypropylen, Polyethylen oder PVC-hart für die Benutzung in Bewässerungs-Systemen bis zu einem Durchmesser von 250 mm.

Techniques d'irrigation - Accessoires de raccord et de commande pour usage dans les systèmes d'irrigation - Caractéristiques techniques et essais

La présente Norme européenne spécifie une méthode permettant de déterminer la résistance à l'usure due au roulement d'une roue lourdement chargée, sur des éprouvettes de mortier moulées, confectionnées avec des matériaux pour chapes à base ciment ou de résine synthétique utilisés en couche d'usure. Cette méthode peut s'appliquer, le cas échéant, à d'autres matériaux de chape utilisés en couche d'usure.
