Before starting the test, select test technique and estimate an initial mass and Δm. Begin the test. If the first specimen fails, decrease the mass of the falling dart by Δm. If the first specimen is not a failure, increase the mass of the falling dart by Δm. Continue the test according to this rule. In brief, decrease or increase by Δm according to whether the earlier specimen is a failure or not. After 20 specimens, calculate the total number of failed specimens N. If N equals to 10, the test is finished. If N is less than 10, add specimens and continue to test until N equals to 10. If N is greater than 10, add specimen and continue the test until the number of non-failure specimens reaches 10. Then the tester calculates the test results automatically according to particular formulas.


This instrument conforms to a number of national and international standards:

  • ASTM D1709
  • JIS K7124-1
  • ISO 7765-1-1988
  • GB/T 9639.1-2008


. .
Basic Applications
  • Impact resistance test of plastic films, sheets and composite films, for example, PE preservative films, PET sheets, wrapping films, and other food package and heavy packages
  • Impact resistance test of paper and paper board
  • Impact resistance test of aluminum plastic composite films and aluminum foils
Extended Applications
  • Test the resistance of the specimen against the falling ball. Mount the specimen on particular clamp for falling ball impact test and choose falling ball of certain weight for the impact test. Check the status of the specimen and establish the impact resistance of the specimen
  • Impact test of shoulder lining. Mount the shoulder lining specimen to the particular clamp and choose falling dart of certain weight for impact test. Check the status of the specimen and establish the impact resistance of the shoulder lining specimen.
