drop dart impact tester

BMC-B1 dart impact tester is suitable for measuring the impact mass and energy when 50% of plastic film or sheet samples are damaged under the free dart impact of a given height.

Product features

1.The system provides two test modes a and B, and automatically judges the test status

2.The falling dart adopts the principle of electromagnetic suction and hanging, which can be released automatically, effectively avoiding the systematic error caused by human factors

3.Sample pneumatic clamping, manual and pedal dual start mode, and the unique design of built-in observation lamp make it convenient for users to carry out test operation quickly and accurately

4.Professional computer software supports multiple unit display of test results, graphical display, output and printing of test process, and clearly and intuitively displays the test results to users

5.Micro printer and standard RS232 interface facilitate the external connection and data transmission between the system and computer

6.Support lystemtm laboratory data sharing system and uniformly manage test results and test reports

Test principle

At the beginning of the test, first select the test method, estimate an initial mass and △ m value, and conduct the test. If the first sample is damaged, use the weight △ m to reduce the falling mass; If the first sample is not broken, the falling mass must be increased with the weight △ m to carry out the test in turn. 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 damage n. if n is equal to 10, the test is completed; If n is less than 10, continue the test after supplementing the sample until n is equal to 10; If n is greater than 10, continue the test after supplementing the sample until the total number of undamaged is equal to 10, and finally the impact result is calculated automatically by the system.
