This product 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.
