impact testing machine experiment

Charpy impact test is a test material notch toughness test, the preparation of the standard is 55 mm long and 10 mm wide and thickness less than 10 mm sample, in a surface processing a 2 mm deep u-shaped or v-notch, control the pendulum is under the impact in setting height relative surface notch, pendulum thrust sample after the height of the swing-up is a measure of the energy absorption after blunt crack sample, which can measure the absorption of energy in the sample fracture, in order to get the notch toughness of the material was tested.Typically, three samples are tested at any one temperature and the results averaged.Charpy tests can be performed on ASTM E23 and ISO 148 at various test temperatures.

The JBS-500 LCD Display Impact Tester was strictly designed according to national standard GB/T3038 “Inspection for pendulum Impact Testing Machine” and GB/229 “Charpy notch Impact Test Method for metal material”. It is also accordance with international standard ISO148, EN100045 and ASTM E23. It is mainly used to determine the anti-impact capability of metal materials under dynamic load. It is the ideal testing equipment for many metal material manufactories, quality inspection departments and universities. The result will display on both digital display and dial gauge, with PLC control, its reliability is very good, JBS Series can use pendulum’s residual impact energy to achieve the raising again of pendulum, so it’s applicable for batch testing tasks.
