Falling dart impact tester BMC-H

for packagingfor compositespaper and cardboard

The BMC-H Free Falling Dart Impact Tester is designed to determine the impact resistance of packaging materials, such as plastic films, laminates, and paper, by means of a free-falling dart from a specified height. This instrument is designed according to ASTM D1709 and ISO 7765-1, using methods A and B.

Product Features

• 7-inch color touchscreen with graphical user interface (GUI).
• Fully automated testing process without manual calculations improves work efficiency.
• Two test modes, A and B, are available.
• Electromagnetic Dart Release Mechanism
• The falling dart operates on the principle of electromagnetic suspension and can be released automatically.
• Pneumatic Sample Clamp
• Pneumatic specimen grips prevent specimen slippage and ensure accuracy of test data.
• Built-in observation lamp allows for easy assessment of specimen condition.
• Users can choose between manual and pedal switch modes to start tests.
• Equipped with micro-printer and standard USB interface.

Test Principle
At the beginning of the test, select the test method as the first step, estimate an initial mass and △m value, and then conduct the test. If the first sample is damaged, use the weight △m to reduce the falling mass; if the first sample is not damaged, use the weight △m to increase the falling mass for the next test. In short, the use of weights to reduce or increase the falling mass depends on whether the previous sample is damaged. After 20 samples are tested, calculate the total number of damaged samples. If n is equal to 10, the test is complete; if n is less than 10, continue the test after supplementing samples until n is equal to 10; if n is greater than 10, continue testing with additional samples until the total number of undamaged samples equals 10. Finally, the system automatically calculates the impact results.

Test Standards
This test instrument conforms to many national and international standards:

ASTM D1709, ISO 7765-1, JIS K7124-1, GB/T 9639.1-2008

Applications
Basic Applications
Film, Foil and Sheeting: It is suitable for testing the impact resistance of plastic films, sheets, foils and composite films with thickness less than 1 mm.
Paper and Paperboard: It is suitable for testing of the impact strength of paper and paperboard.
Extended Applications
Ball Drop Test: It is suitable for the falling ball impact test of the specimen. The specimen is clamped on the drop (falling) ball impact test fixture, and the falling ball of a certain quality is selected to hit the specimen from a certain height. The damage of the specimen is checked and the impact resistance of the specimen is judged.
Multi-angle impact Test: It is suitable for the multi-angle impact of bottle caps and other materials.
