STRENGTH GUARANTEE TEST METHOD AND APPARATUS USED THEREIN

摘要

The purpose of the present invention is to improve reliability of a testing method for guaranteeing strength of ceramic components. In this strength guarantee test method, unused ceramic components are totally inspected. The method is characterized in that a previously set load is applied to the ceramic components, and at the same time, acoustic emission measurement is performed, and ceramic components, which do not break during the test and have a threshold value acoustic emission energy change quantity or less, are determined acceptable.
