Fine ceramics (advanced ceramics, advanced technical ceramics). Mechanical properties of monolithic ceramics at room temperature. Determination of compressive strength1 Scope This International Standard specifies a method for the determination of nominal compressive strength of advanced monolithic technical ceramic materials at room temperature.

NOTE 1 Requirements in this International Standard are consistent with those developed by the Codex Alimentarius Commission (CAC/RCP 19-1979
