Drop Dart Impact Testing Equipment
Drop Dart Impact Testing Equipment
Product Code : BMC-B1
Brand Name : Labthink
Product Description
BMC-B1 Drop Dart Impact Testing Equipment    is designed to measure impact resistance property of plastic films, paper and other packaging materials using free falling dart method.

Principle:

Before starting the test, choose test method, and estimate an initial mass and Δm. Start the test. If the first specimen fails, decrease the mass of the falling dart by Δm. If the first specimen is not a failure, increase the mass of the falling dart by Δm. Continue the test according to this rule. In brief, increase or decrease by Δm according to whether the former specimen is a failure or not. After 20 specimens, calculate the total number of failed specimens N. If N equals to 10, the test is over. If N is less than 10, add specimens and continue to test until N equals to 10. If N is greater than 10, add specimen and continue the test until the number of non-failure specimens reaches 10. Then the tester calculates the test results automatically according to specific formulas.

Standards:

ISO 7765-1, ASTM D1709, JIS K7124-1

Features:

  • 2 test methods of A & B and automatic determination of testing status
  • Electromagnetic suspension and automatic release of the falling dart reduce the errors caused by manual operation
  • Pneumatic clamping, 2 starting modes of manual and pedal switch and built-in observation light are convenient to the user's operation

Applications:

Basic Applications:
1. Plastic films, sheets and composite films e.g. PE preservative films, wrapping films, PET sheets and other food package and heavy packages
2. Aluminum foils and aluminum plastic composite films
3. Paper and paper board
Extended Applications:
1. Test the resistance of the specimen against the falling ball. Mount the specimen on specific clamp for falling ball impact test and select falling ball of certain weight for the impact test. Check the status of the specimen and determine the impact resistance of the specimen
2. Impact test of shoulder lining. Mount the shoulder lining specimen to the specified clamp and select falling dart of certain weight for impact test. Check the status of the specimen and determine the impact resistance of the shoulder lining specimen.
