EN ISO 23146:2016 Fine ceramics (advanced ceramics@ advanced technical ceramics) - Test methods for fracture toughness of monolithic ceramics - Single-edge V-notch beam (SEVNB) method
This International Standard specifies a method for determining the fracture toughness of advanced ceramics. This method uses one-sided notched V-notched bending specimens that are subjected to a 4-point bend to the point of failure. The method applies to monolithic ceramics with a grain size or a size of another typical microstructure feature of at least about 1 µm. The use of this International Standard for yttrium-stabilized polycrystalline tetragonal zirconia (Y-TZP) is not recommended. The process may also be unsuitable for other high-toughness or soft ceramic materials where a sharp crack does not form at the base of the V-notch.
