Advanced technical ceramics - Thermomechanical properties of monolithic ceramics - Part 4: Determination of flexural creep deformation at elevated temperatures

This Part of EN 820 describes a procedure for undertaking flexural creep tests at elevated temperatures on advanced technical ceramics, mainly for the purposes of comparison of deformation behaviour of materials under stressed conditions and under any appropriate atmospheric condition.
NOTE   This European Standard does not provide a method of acquiring engineering performance data since the stress distribution under flexural loading is indeterminate.

Hochleistungskeramik - Thermomechanische Eigenschaften monolithischer Keramik - Teil 4: Bestimmung der Kriechverformung unter Biegebeanspruchung bei erhöhten Temperaturen

Dieser Teil von EN 820 legt ein Verfahren zur Durchführung von Kriechprüfungen unter Biegebeanspruchung
bei erhöhten Temperaturen an Hochleistungskeramiken fest, hauptsächlich, um das Verformungsverhalten
von Werkstoffen unter Beanspruchung und bei geeigneten Umgebungsbedingungen zu vergleichen.
ANMERKUNG Diese Europäische Norm liefert kein Verfahren für die Gewinnung technisch anwendbarer Daten, weil
die Spannungsverteilung unter Biegebeanspruchung unbestimmt ist.

Céramiques techniques avancées - Méthodes d'essai des céramiques monolithiques - Propriétés thermomécaniques - Partie 4: Détermination de la déformation par fluage en flexion à températures élevées

La présente Partie de l'EN 820 décrit un mode opératoire pour réaliser des essais de fluage en flexion à des
températures élevées sur des céramiques techniques avancées, principalement à des fins de comparaison du
comportement en déformation de matériaux soumis à une contrainte et dans des conditions atmosphériques
appropriées.
NOTE La présente Norme européenne ne fournit pas de méthode d'acquisition de données de performances
d'ingénierie, car la répartition des contraintes sous charge en flexion est indéterminée.
