F0008 - Falling Dart Impact Tester

Product details

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.

Applications:
• Flexible films
