IDM Instruments says its Falling Dart Impact Tester can determine the energy required to cause Polyethylene Film to fail under specified conditions.
According to IDM, the instrument records its data after an impact of a free-falling dart, with the energy expressed in terms of weight or mass of the dart falling from a specified height, which would result in 50% failure of specimens tested.
The IDM Falling Dart Impact Tester is said to be manufactured with reference to international standards used for Flexible films, with two test methods achievable.
IDM says Test Method A is generally used for films whose impact resistances require masses of about 50g to 2kg to fracture them. Whereas Test Method B is generally used for films whose impact resistances require masses of about 0.3kg to 2kg to fracture them.
