Dart Impact Tester
Availability: In Stock
Brand: Laboratory Testing Instruments
The Dart Impact Tester is used to determine the impact resistance of plastic films, sheets, and flexible packaging materials. The instrument evaluates a specimen’s resistance to impact from a falling dart under specified test conditions.
During testing, a dart of specified mass is released from a predetermined height onto the specimen. The specimen is then evaluated for failure to assess its impact resistance. This test helps manufacturers evaluate the durability and performance of plastic films and packaging materials.
Laboratory Testing Instruments offers Dart Impact Testers for testing applications in the plastic film, packaging, and flexible materials industries.
Dart Impact Tester for Plastic Films
The Dart Impact Tester evaluates the impact resistance of plastic films by dropping a dart onto a clamped specimen from a specified height.
The impact applied to the specimen depends on the dart mass and drop height. Different test methods use different dart head diameters, dart masses, and testing conditions.
The instrument features an electromagnetic dart hold-and-release mechanism, an adjustable drop height, and a circular annular clamping mechanism to hold the specimen securely during testing. A digital LED display supports test operation and result indication.
The Dart Impact Tester is designed for testing in accordance with the following standards, subject to the applicable product configuration:
IS 2508:1984 (R2003)
ASTM D1709-16A
Working Principle of Dart Impact Tester
The Dart Impact Tester determines the impact resistance of plastic films and flexible packaging specimens by releasing a weighted dart from a specified height.
To perform the test:
Place the plastic film specimen over the test opening.
Secure the specimen using the circular annular clamping mechanism.
Select the required dart and drop height according to the applicable test method.
Position the dart at the specified drop height.
Release the dart using the electromagnetic hold-and-release mechanism.
Examine the specimen for failure after impact.
Record the test result according to the applicable test method.
The instrument provides controlled dart release and adjustable drop height to help maintain consistent testing conditions.
