What is this standard about?
This document describes a test method that covers the determination of fracture resistance of monolithic ceramics at room temperature by the indentation fracture (IF) method.
This document is intended for use with dense monolithic ceramics and whisker- or particulatereinforced ceramics which are regarded as macroscopically homogeneous. It does not include monolithic silicon nitride ceramics for bearing balls and continuous-fibre-reinforced ceramics composites.
This document is for material development, material comparison, quality assurance, characterization and reliability data generation.
Indentation fracture resistance, KI,IFR, as defined in this document is not to be equated with fracture toughness determined using other test methods such as KIsc and KIpb.
