Free-Falling Dart Method Impact Tester measures the energy that causes plastic film and sheet to fail under specified conditions of impact of a free falling dart.
The impact energy is expressed in terms of the weight/mass of the missile falling from a specified height which would result in 50% failure of specimens tested.
Free-Falling Dart Method Impact Tester gives a quantified analysis of sample quality, uniformity, thickness and strength.
