impact energy calculation charpy test

1.Application:

JBS-B Touchscreen Digital Display Charpy Impact Testing Machine 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.

This series tester is operated semi-automatically, the pendulum of the machine can be raised or released automatically. Be applicable for continuing testing in different kinds of laboratories and other metallurgy industrial manufactories.

2.Standards:

ISO148, EN10045, ASTM E23, GB/T3808-2002 ,GB/T229-2007.

4. Features:

4.1.Pendulum rising, impact, free releasing is realized as automatically by micro control meter or

remote control box.

4.2.Safety pin guaranties the impact action, standard protection shell to avoid any accident.

4.3.Pendulum will automatically rising and ready for next impact action after specimen breakout.

4.4.With two pendulums (big and small), LCD touching screen display the energy loss, impact

tenacity, rising angle, and test average value, meantime the dial scale show test result as well.

4.5.Built-in micro printer to print test result.
