BS EN 843-4:2005

This standard BS EN 843-4:2005 Advanced technical ceramics. Mechanical properties of monolithic ceramics at room temperature is classified in these ICS categories:

• 81.060.30 Advanced ceramics

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.
