This part of CEN/TS 14425 describes a method for the determination of the fracture toughness of
advanced technical ceramics. The procedure makes use of V-notched bars, which are loaded in 4-
point bending until failure. It is applicable to ceramics with a grain size or major microstructural feature
size larger than about 1 μm.
