Use and Characteristic of the Tester                           

JBD-300W-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 JBD-300W 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 . This equipment used compression engine refrigeration technology of the USA, the use of the principle of heat balance and mixing method of circulation to achieve uniformity of the sample auto-cooling and temperature,
