II. Falling dart impact tester works At baseline, first select the test method to estimate an initial mass and Δm values, to test if the first specimen damage, with the weights Δm reduce the drop-weight; if the first is not broken, should fall with increased body mass weight Δm so tested. In short, the use of weight reduction or increase in body weight down, depending on the previous sample is broken. 20 specimens, the calculation of the total number of damaged N, if N is equal to 10, the test is completed; if N is less than 10, additional samples, to continue to test until N is equal to 10; if N is greater than 10, additional samples, to continue to not broken until the total number of trials equal to 10 so far, and finally by the system automatically calculates the impact of the results.

III. Falling dart impact tester basic steps System power → Select → estimated test methods and Δm → initial impulse to increase or decrease based on the results of the impact of the system automatically calculates the progress of Δm → → automatically determine whether conditions meet the end of the test result → Display → Test → Test Report printed over.
