300J 500J 750J ASTM E23 Pendulum Charpy Impact Testing Machine

They are mainly used to determine the anti-impact capability of metal materials under dynamic load. They are the best testing equipments for many metal material manufactories, quality inspection departments and universities. The results will be displayed on both digital screen and dial gauge. JBW-C series impact testers can use pendulum’s residual impact energy to achieve the re-raising of pendulum, so as to save energy. The results can be printed out, be applicable for mass testing departments.

 

2. Standards:

JBS-B series impact testers are strictly designed according to the standards ASTM E23, ISO148-2006 and GB/T3038-2002, GB/229-2007.
