Abstract
The present invention is intended for improving the reliability of a strength proof test method for ceramic parts. The present invention is directed to a strength proof test method for making total inspection of ceramic parts, including: applying a prescribed load to the ceramic parts; and at the same time, making an acoustic emission measurement, in which the ceramic parts are considered as passing when the ceramic parts are not fractured in the test and the variation of acoustic emission energy is not more than a threshold.
