Impact Tester

The Impact Tester is a laboratory test machine, which is suitable to determine the crushability test that was developed by F.C. Bond.

  • The Impact Tester consists of two pendulum-mounted hammers, each weighing approximately 30 lb, and mounted to simultaneously strike equal blows on opposite sides of each rock specimen.
  • The crushability test is to be performed on ten or more representative pieces of broken stone. Each is to pass a 3-in. square opening and be retained on a 2-in. square opening. More specimens will increase the reliability of the test results.
