Methods of test for dense shaped refractory products - Part 11: Determination of resistance to thermal shock

This European Standard describes two alternative methods for determining the resistance to thermal shock of dense shaped refractory materials by an air quenching method, which proved to give the most reliable results when compared with the behaviour of refractories in furnace linings.
Method B can also be applied to unshaped refractory materials.

Prüfverfahen für dichte geformte feuerfeste Erzeugnisse - Teil 11: Bestimmung der Temperaturwechselbeständigkeit

Diese Europäische Norm legt zwei alternative Verfahren zur Bestimmung der Temperaturwechselbeständigkeit von dichten geformten feuerfesten Erzeugnissen durch Abschrecken an Luft fest, für die nachgewiesen wurde, dass sie, verglichen mit dem Verhalten von feuerfesten Erzeugnissen in Ofenauskleidungen, die zuverlässigsten Ergebnisse liefern. Verfahren B ist auch auf ungeformte feuerfeste Werkstoffe anwendbar.

Méthodes d'essai pour produits réfractaires façonnés denses - Partie 11 : Détermination de la résistance au choc thermique

La présente Norme européenne définit deux méthodes alternatives permettant de déterminer la résistance aux chocs thermiques des matériaux réfractaires façonnés denses par une méthode de trempe à l’air ; il a été établi que, par comparaison avec le comportement des réfractaires placés dans les revêtements de fours, ces méthodes donnaient des résultats plus fiables.
La méthode B peut aussi être appliquée aux matériaux réfractaires non façonnés.
