Drop Dart Impact Testing Machine ASTM D1709 - 1

PARAM® BMC-B1 Falling Dart Impact Tester Professional Technology • 2 test methods of A & B and automatic determination of testing status • Electromagnetic suspension and automatic release of the falling dart reduce the error 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 • Professional software supports multi-unit results display, graphic display of testing process and data export and printing • Equipped with RS232 port and micro printer port which is convenient to the data transmission and PC • Support Lystem™ Lab Data Sharing System for uniform and systematic data management Test Principle At the beginning of the test, choose test method, and estimate an initial mass and Am. Start the test. If the first specimen fails, decrease the mass of the falling dart by Am. If the first specimen is not a failure, increase the mass of the falling dart by Am. Continue the test according to this rule. In brief, increase or decrease by Am 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. This instrument conforms to various national and international standards: Impact resistance tests of plastic films, sheets and composite films e.g. PE preservative films, Basic wrapping films, PET sheets and other food package and heavy packages Applications Impact resistance test of aluminum foil and aluminum plastic composite film Impact resistance test of paper and paper board 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. Extended Check the status of the specimen and determine the impact resistance of the specimen Applications 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.
