1.Function
JB-300 manual pendulum impact tester is mainly used to determine the anti-impact capability of ferrous metal materials with high toughness, especially for steel and iron and their alloy, under dynamic load. It is designed according to national standards GB229-2007 "Metallic Material-Charpy Pendulum Impact Test Method" and standards of ISO148 and ASTM E23. It's operated manually, simple and reliable.
