This standard specifies the specific requirements for the equipment and samples used in the high-temperature bending strength test of engineering ceramics, the test procedures and the treatment methods of the test results. This standard applies to the determination of the three-point and four-point bending strength of high-strength engineering ceramics used as mechanical parts and structural materials at high temperatures, and also applies to the determination of the bending strength of high-strength functional ceramics at high temperatures. Method for determination of point bending strength.
