Function and characteristics
The machine is mainly used for the determination of metallic materials to resist the impact performance under dynamic load in order to determine the material properties under dynamic load.
The machine is semi-automatic testing machine, easy operation, high efficiency, raise pendulum, impact, put down the pendulum are the electrical control, and can use the residual thrust energy of the sample automatically raised the pendulum make the next test Preparation, especially for laboratory of do continuous impact test and metallurgy, machinery manufacturing and other industries of do a lot impact testing. JB-300B-type impact test machine meet the national standard GB/T3808-2002 "test of pendulum type impact testing machines", according to national standard GB/T229-2007 "metal Charpy notched impact test method” to do impact test of metallic materials.
