XJB-30 mainly used to test plastic, film, or sheet thickness below 1mm, impact by falling dart, check the energy when 50% of test specimen broken.
Conform with standard: ISO 7765, ASTM D1709, GB 9639.
Falling dart impact is a traditional method for evaluating the impact strength or toughness of a plastic film. This test uses a single dart configuration and a single drop height, while varying the weight of the dart. Test results can be used either as a quality control evaluation or for end use comparisons.
Film samples that can be cut to 230 mm x 230 mm (9" x 9") specimens
A minimum of 30 specimens are required for the test
