Effective Quality Control of Charpy Pendulum Impact Test

Through using standard impact specimens to verify the precision of the pendulum impact machine, and analyzing the fractured specimens that has been tested, a quick periodic check to the pendulum impact machine has been done. An apt solution shall be used when a bias factor of the Charpy pendulum impact test has been found. So a high precision of the Charpy pendulum impact test will be guaranteed and an effective quality control can be done at high level.
