Natural stone test methods - Determination of sensitivity to changes in appearance produced by thermal cycles

This document specifies a method to assess possible alterations of natural stones (mainly visible sensitivity to oxidation processes) under the effect of sudden changes in temperature (thermal shock).

Prüfverfahren für Naturwerkstein - Bestimmung der Empfindlichkeit gegen Änderungen des äußeren Erscheinungsbildes durch thermische Zyklen

Dieses Dokument legt ein Verfahren zur Bewertung möglicher Verwitterungen von Natursteinen (vorwiegend sichtbare Empfindlichkeit auf Oxidationsprozesse) unter der Einwirkung plötzlicher Temperaturwechsel (thermischer Schock) fest.

Méthodes d'essai pour pierres naturelles - Détermination de la sensibilité aux changements d'aspect induits par des cycles thermiques

Le présent document décrit une méthode permettant d’évaluer les modifications possibles des pierres naturelles (sensibilité aux procédés d’oxydation généralement visible) sous l’effet de changements brusques de température (choc thermique).

Preskušanje naravnega kamna - Ugotavljanje občutljivosti pri spremembi videza, nastalega pri termičnih ciklih

Ta evropski standard določa metodo za ocenjevanje morebitnih sprememb naravnega kamna (predvsem vidne občutljivosti na oksidacijske procese) zaradi nenadnih sprememb temperature (temperaturni šok).
