BMC-AB Dart Impact Tester Test principle: At the beginning of the dart drop test, the test method is first selected, and an initial mass and Δ m value are estimated to be tested. If the first sample is damaged, use the weight △ m to reduce the mass of the falling body; if the first sample is not broken, the weight should be increased by using the weight △ m to increase the falling mass. In summary, using a weight to reduce or increase the weight of the body depends on whether the previous sample is broken. After the test of 20 samples, 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 after the sample is replenished until N is equal to 10; if N is greater than 10, continue the test after the sample is replenished until it is not damaged. The total number is equal to 10, and finally the system automatically calculates the dart impact strength result. Features: 1.
