PURPOSE:To perform the endurance test of a test piece or valve in a short time with a low cost, by simulating prescribed operation conditions in prescribed simulated operation circumstances to operate the test piece or valve. CONSTITUTION:An impact load is applied to test pieces X and Y through a lower gripping tool 3 under the circumstances of a specific gas composition or the like by a vibrator. The stroke of the vibrator, the load, a test chamber pressure, etc. are recorded, and reduction of the weight, the damage condition of a contacting face, etc. after the test are observed to evaluate the durability. Thus, the endurance test of test pieces X and Y is performed in a short time with a low cost. |
