Principle

Before starting the test, choose test method, and estimate an initial mass and m. Start the test. If the first specimen fails, decrease the mass of the falling dart by m. If the first specimen is not a failure, increase the mass of the falling dart by m. Continue the test according to this rule. In brief, increase or decrease by m 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.
