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.

The Falling Dart Impact Tester (drop dart impact testing equipment) covers the determination of the energy that causes Polyethylene Film to fail under specified conditions, with the impact of a free-falling dart.  This energy is expressed in terms of weight (mass) of the dart falling from a specified height, which would result in 50% failure of specimens tested.

Conform with standard: ISO 7765, ASTM D1709, GB 9639. JIS K7124, AS/NZS 4347.6

Scope:
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.

Specimen size:
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

Other Name: drop impact tester, Falling weight impact tester, Falling dart impact tester, plastic pipe free falling dart impact testing machine.
