Building lime - Part 2: Test methods

This document specifies the test methods for all building limes covered by EN 459 1. They can also be applied to other lime materials, the standards for which call up these methods.
This document specifies in Table 2 the methods used for the chemical analyses and the determination of physical properties of building limes.
This document specifies the reference methods and, in certain cases, an alternative method which can be considered to be equivalent. In the case of a dispute, only the reference methods are used.
Any other methods may be used provided they are calibrated, either against the reference methods or against internationally accepted reference materials, in order to demonstrate their equivalence.

Baukalk - Teil 2: Prüfverfahren

Dieses Dokument legt die Prüfverfahren für alle Baukalke, die in EN 459 1 enthalten sind, fest. Die Verfahren können auch für andere Kalkmaterialien gelten, sofern in den entsprechenden Normen darauf verwiesen wird.
Dieses Dokument legt in Tabelle 2 die Verfahren für die chemische Analyse und die Bestimmung der physikalischen Eigenschaften von Baukalken fest.
Dieses Dokument legt die Referenzverfahren und in einigen Fällen Alternativverfahren fest, deren Ergebnisse denen des Referenzverfahrens entsprechen. Im Streitfall sind die Referenzverfahren maßgebend.
Werden andere Verfahren angewendet, so sind diese gegen die Referenzverfahren oder gegen international anerkannte Referenzmaterialien zu kalibrieren, um ihre Eignung nachzuweisen.

Chaux de Construction - Partie 2 : Méthodes d'essais

La présente Norme européenne décrit les méthodes d'essai applicables à toutes les chaux de construction faisant l'objet de I'EN 459-1. Il peut aussi être appliqué à d’autres matériaux à base de chaux dont les normes font appel à ces méthodes.
La présente norme européenne prescrit les méthodes utilisées pour les analyses chimiques dans le tableau 2 et la détermination des propriétés physiques des chaux de construction.
Le présent document décrit les principales méthodes d’analyses chimiques. Les méthodes de références et, dans certains cas, des variantes qui peuvent être considérée comme équivalentes.
Toute autre méthode peut être utilisée à condition qu'elle soit étalonnée, soit par rapport aux méthodes de référence, soit aux matériaux de référence internationalement acceptés, afin de démontrer leur équivalence.
