Falling Dart Impact Tester

Home » Falling Dart Impact Tester

The Falling Dart Impact Tester 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.

For example: Using Method A, the unit employs a dart with a 38mm diameter hemispherical head, dropped from a height of 660mm. This unit may be used for films whose impact resistance requires masses of approximately 50gms to 2 kg to fracture them.
