Methods of test for mortar for masonry - Part 21: Determination of the compatibility of one-coat rendering mortars with substrates
This European Standard specifies a test method for the evaluation of the compatibility with given backgrounds of One-Coat (OC) rendering mortars. The evaluation is based on the determination of the adhesion strength and water permeability of the hardened render applied on tested substrates, after exposure to weathering cycles.
Prüfverfahren für Mörtel für Mauerwerk - Teil 21: Bestimmung der Verträglichkeit von Einlagenputzmörteln mit Untergründen
Diese Europäische Norm legt die Verfahren zur Bewertung der Verträglichkeit von Einlagenputzmörteln (OC) mit den in Frage kommenden Untergründen fest. Die Bewertung basiert auf der Bestimmung der Haftfestigkeit und der Wasserdurchlässigkeit des erhärteten Putzes, der auf geprüften Untergründen aufgetragen und bewittert wurde.
Méthodes d'essai des mortiers pour maçonnerie - Partie 21: Détermination de la compatibilité des mortiers d'enduit extérieur mono-couche avec les supports
La présente Norme européenne décrit une méthode de détermination de la compatibilité des mortiers d'enduit mono-couche (MC) avec les supports sur lesquels ils doivent etre appliqués.
Cette détermination est basée sur la mesure de l'adhérence et de la perméabilité a l'eau de l'enduit durci appliqué sur des supports définis, apres cycles de conditionnement.
