MS ISO 18756:2008 Fine ceramics (Advanced ceramics, advanced technical ceramics)-determination of fracture toughness of monolithic ceramics at room temperature by the surface crack in flexure (SCF) method (ISO 18756:2003, IDT)

This International Standard describes a test method that covers the determination of fracture toughness of monolithic ceramic materials at room temperature by the surface crack in flexure (SCF) method.
This International Standard is intended for use with monolithic ceramics and whisker-or particulate-reinforced ceramic composites.
The test method is applicable to materials with either flat or rising crack growth resistance curves. This method is similar to ISO 15732 except that precracks are smaller and are made by a different procedure. The methods should procedure similar or identical results for materials with a flat R-curve.
