SIST EN 843-4:2005

Advanced technical ceramics - Mechanical properties of monolithic ceramics at room temperature - Part 4: Vickers, Knoop and Rockwell superficial hardness

This part of EN 843 defines conditions for conducting, and provides guidelines concerning the value that may be ascribed to the results of, standard hardness tests when applied to advanced monolithic technical ceramics. It is assumed that the calibration and test procedures employed are exactly those for metallic materials. This European Standard refers to Rockwell A, Rockwell N-scale, Vickers, and Knoop hardness testing, as described in existing international standards.

Hochleistungskeramik - Mechanische Eigenschaften monolithischer Keramik bei Raumtemperatur - Teil 4: Härteprüfung nach Vickers, Knoop und Rockwell

Dieser Teil von EN 843 definiert Bedingungen für die Durchführung von Härteprüfungen an monolithischer
Hochleistungskeramik und gibt Richtlinien für die Bewertung der erhaltenen Ergebnisse. Es wird voraus-
gesetzt, dass Kalibrierung und Prüfablauf exakt denen für metallische Werkstoffe entsprechen. Diese
Europäische Norm nimmt Bezug auf die Härteprüfung nach Rockwell A, Rockwell N, Vickers und Knoop in
Übereinstimmung mit den einschlägigen Internationalen Normen.
