Drop Weight Impact Testing Machines for Plastics.

Model BMC-B1 Falling dart impact tester is designed and manufactured according to ASTM D 1709. It is applicable in energy test that causes plastic films and foils to fail under specified conditions of impact of a freefalling dart.

This energy is expressed in terms of the weight of the dart falling from a specified height which would result in 50% failure of specimens tested.


  • Compatible with state and international standards (ASTM D1709、JISK7124、GB 9639).
  • Novelty mechanical model, considerate design.
  • Two test methods integration: A & B.
  • Micro-computer processes test results.
  • Pneumatic clamping and releasing decrease test time and errors.
  • Test procedure requires no manual drawing and mark, data and parameters are displayed by LCD.
  • System identifies, calculates test data automatically, and requires no manual intervention. Test stops automatically, results are displayed by multifold units, micro-printer prints results.
