Methods of test for screed materials - Part 3: Determination of wear resistance - Böhme
This document specifies a method for determining the wear resistance of moulded specimens made from cementitious screed material, primarily for hard aggregate wearing screed materials or optionally for other screed materials. The method is also suitable for specimens cut from floor screed. This method is unsuitable for synthetic resin screed materials.
Prüfverfahren für Estrichmörtel und Estrichmassen - Teil 3: Bestimmung des Verschleißwiderstandes nach Böhme
Diese Europäische Norm legt ein Verfahren zur Bestimmung der Verschleißfestigkeit von aus Zementestrichmörtel geformten Prüfkörpern, hauptsächlich für Estrichmassen für die Hartstoffschicht oder wahlfrei für andere Estrichmörtel/Estrichmassen, fest. Das Verfahren ist auch für Prüfkörper geeignet, die aus verlegtem Estrich geschnitten wurden. Das Verfahren ist für Kunstharzestrichmörtel nicht geeignet.
Méthodes d'essai des matériaux pour chapes - Partie 3: Détermination de la résistance à l'usure Böhme
Le présent document spécifie une méthode permettant de déterminer la résistance à l’usure sur des éprouvettes moulées composées de matériaux pour chapes à base de ciment, principalement pour des matériaux utilisés pour les couches d’usure incorporant des granulats durs ou éventuellement pour d’autres matériaux pour chapes. Cette méthode s’applique également aux éprouvettes prélevées d’une chape. Elle ne s’applique pas aux matériaux pour chapes en résine synthétique.
Metode preskušanja mešanice za estrih - 3. del: Ugotavljanje odpornosti proti obrabi po Böhmeju
Ta dokument določa metodo za ugotavljanje odpornosti proti obrabi oblikovanih preskušancev iz cementnih mešanic za estrihe, ki so namenjene predvsem za mešanice za estrihe iz trdih agregatov ali izbirno za druge mešanice za estrihe. Ta metoda je primerna tudi za preskušance, izrezane iz estrihov. Metoda ni primerna za estrihe iz sintetične smole.
