Test Principle
Before starting the test, choose test method, and estimate an initial mass and Am. Start the test. If the first specimen fails, decrease the mass of the falling dart by Am. If the first specimen is not a failure, increase the mass of the falling dart by Am. Continue the test according to this rule. In brief, increase or decrease by Am 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.
This instrument conforms to various national and international standards: ISO 7765-1-1988, ASTM D1709, JIS K7124-1, GB/T 9639.1-2008
