ASSTM C 1161 (C-1161) determines the flexural strength of advanced ceramic materials at ambient temperature. Four-point-1/4 point and three-point loadings are the standard with rectangular specimens. The values obtained from this test method may be used in material development, quality control, characterization, and design. The material is assumed to be isotropic and homogeneous, the modulus of elasticity in tension and compression are identical, and the material is lenearly elastic. TestResources provides machines, grips, equipment, and fixtures for testing in accordance with ASTM C1161.
