Test principle and procedure of falling dart impact tester

The falling dart impact tester is suitable for the determination of the impact mass and energy of the plastic film or sheet when 50% of the sample is damaged under the free falling dart impact of a given height Through the impact resistance test, it can prevent the packaging surface from being damaged due to the insufficient toughness of packaging materials when impacted and dropped, and effectively avoid the damage caused by the impact or drop in the circulation of products Three springs rock falling dart impact tester - Falling Dart impact tester? Test principle: at the beginning of falling dart test, first select the test method, estimate an initial mass and △ m value, and carry out the test If the sample is damaged, use the weight △ m to reduce the falling mass; if the sample is not damaged, use the weight △ m to increase the falling mass in order to test In summary, the use of weights to reduce or increase the mass of the drop depends on whether the previous specimen is damaged After 20 samples are tested, calculate the total number of damages n if n is equal to 10, the test is completed; if n is less than 10, continue the test until n is equal to 10; if n is greater than 10, continue the test until the total number of undamaged samples is equal to 10, and the system will automatically calculate the impact strength of dart Basic operation steps of dart impact tester: (1) power on the system; (2) select test method; (3) estimate initial impulse and m value; (4) increase or decrease m value according to impact result; (5) automatically calculate progress by the system; (6) automatically judge whether the end condition is met; (7) display test result; (8) print test report; (9) end of test Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd has advanced testing technology, packaging testing equipment and professional laboratory It is committed to providing comprehensive and quality control solutions for industry customers, falling dart impact tester bmc-ab Sanquan Zhongshi!
