ISO 7765 Plastic Film Impact Resistance Tester determinates the energy that causes plastic film to fail under specified conditions of impact of a free-falling dart. This 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.
The free falling dart tester can give a quantified analysis of sample quality, uniformity, thickness and strength.
