Dart impact testing machine

A testing machine for measuring the energy when 50% of the sample is damaged under the free falling dart impact at a given height. It is suitable for plastic film, sheet and steel plate coating. Meet ASTM d1709 methods a and B, JIS k7124 and other standards. It can be used in scientific research, teaching, industrial and mining enterprises, laboratories, research institutes and quality supervision departments.
