Falling Dart Impact Tester
The falling dart impact test is a straightforward and efficient way to test the impact strength or toughness of films. It allows the measurement of the material’s impact resistance, by dropping a free-falling dart and recording the resulting effect on the film, which is clamped in place.
There are two main methods for testing, Method A and Method B. They are differentiated by the height of the drop and the diameter of the dart head.
Falling Dart Impact Test - Method A
Method A uses a dart head of 38±1mm and is made of low-density materials like aluminum or phenolic plastic. The drop height is 0.66±0.01m.
Falling Dart Impact Test - Method B
Method B uses a dart head of 50±1mm and is made of tough materials such as polished stainless steel. The drop height is 1.50 ±0.01m.
Saicheng falling dart impact tester can be used for the determination of impact resistance of packaging materials such as plastic films, laminates by a free falling dart from a certain height. This instrument is designed according to ASTM D1709, ISO 7765-1 with method A & B.
BMC-H Free Falling Dart Impact Tester
BMC-H Free Falling Dart Impact Tester is designed for determination of the impact resistance of packaging materials such as plastic films, laminates and paper by a free-falling dart from a certain height.
