JB-300B-type impact testing machine is used for measuring the metal material resistance performance under dynamic load, in order to determine the material properties under dynamic load. Model JB-300B tester is developed strictly according to GB/T3808-2002 model swinging hammer impact tester international standard .It does impact test to mental material according to GB/T229-1994 impact test method of mental gap.The maximum impact energy is 300 Joule with a hammer of 150 Joule .Dimension of breaking surface of the sample is 10*10mm. It mainly does test to black metal, especially to steel and its alloy.
