Plastic Films Impact Strength Testing Machine ASTM D1709

Product Description

FDI-01 Plastic Films Impact Strength Testing Machine ASTM D1709 is designed to measure impact resistance property of plastic films, sheeting, paper and foils. It is based on free falling dart method and equipped with LCD display.


Principle:


Before starting the test, choose test method, and estimate an initial mass and m. Start the test. If the first specimen fails, decrease the mass of the falling dart by m. If the first specimen is not a failure, increase the mass of the falling dart by m. Continue the test according to this rule. In brief, increase or decrease by m 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:

Basic Applications:

Extended Applications:

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
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.
