This International Standard describes a test method for the determination of the fracture toughness of monolithic ceramic thin plates at room temperature by the single-edge precracked plate method or the single-edge V-notch plate method. This International Standard is intended for use with monolithic ceramics and whisker- or particulatereinforced ceramics which are regarded as macroscopically homogeneous. It does not include continuous-fiber-reinforced ceramics composites. This International Standard is applicable to ceramic thin plates with thickness of 0,2 to less than 1,0 mm. The single-edge V-notch plate method can be applied to monolithic ceramics with a grain size larger than about 1 ?m. The use of this method is inappropriate for yttria tetragonal zirconia polycrystal material (Y-TZP) which consists of homogeneous fine submicron grains. The method might also be unsuitable for some other very tough or soft ceramics in which a sharp crack does not form at the root of the V-notch. This International Standard is for material development, material comparison, quality assurance, characterization, reliability and design data generation.
