适用范围：This part of EN 843 specifies methods for determining the nominal flexural strength of advanced monolithictechnical ceramic materials at ambient temperature. The available loading geometries are three- and four-pointflexure, using rectangular section test pieces of two prescribed geometries: 20 mm support span (A) and 40 mmsupport span (B).NOTE This part of EN 843 differs from ISO 14704 (see Bibliography) in respect of span A (not included in the ISOversion), the absence of the 30 mm span option, and the required use of a fully articulating test jig.The test applies to materials with grain size less than 200 pm.The test prescribes four categories of surface finish applied to the test pieces: Ⅰ: as-fired or annealed after machining; Ⅱ: standard finishing by grinding; Ⅲ: standard finishing by lapping/polishing; Ⅳ: machined using agreed grinding procedures and material removal rates.
