Description
The dart drop tester is an easy-to-use, ergonomically designed instrument used to measure the impact resistance of plastic film, coated paper and other materials utilizing the free falling dart method.
How it Works
A pneumatic sample clamp is used to secure the specimen in place for ease of operation and operator safety. The operator needs to simultaneously activate dual switches mounted on either side of the instrument to engage the clamp and initiate the free falling dart.ย In addition, the dart drop tester provides a dual clamping sequence. The first phase utilizes low-pressure to safely clamp the sample followed by a high-pressure clamp prior to testing. The final phase of the test is completed with an automatic dart release.

ASTM D1709 – Method B
Dart 50.8 mm diameter (stainless steel)

Dart Options
Phenolic head: 38.1 mm (1.5 in) diameter, 50 g
Aluminum head: 38.1 mm (1.5 in) diameter, 50 g
Stainless Steel head: 50.8 mm (2 in) diameter, 300 g
Air Requirements:ย ย
You will need a compressed air source for the pneumatic clamp system.
The Dart Drop Tester is configured for defined dart release intervals, the input air pressure needs to be set to 60 psi (414 kPa).
A lower input air pressure will slow down the release mechanism, and a higher air pressure will speed up the release mechanism.
