In order to investigate the effectiveness of high-temperature proof testing in silicon nitride, static fatigue tests at l000℃ were conducted using the specimens with and without proof testing at l000℃. The experiments were conducted in air under four-point bending. The times to failure of survivors of proof testing were measured and compared with that of as-received specimens, and the relation-ship between the proof-testing effect and the proof-testing conditions was investigated. It was clarified that high-temperature proof testing was influenced by oxidation of specimen surface and loading rate of proof stress.
