Weight Drop Impact Test Device
Product Information
Testing Principle:
At the beginning of the test, select the test method and estimate an initial mass ?m. Start testing. If the first sample fails, reduce the mass of the dropped weight by ?m. If the first sample did not fail, increase the mass of the dropped weight by ?m. Continue testing according to this rule. In short, increase or decrease the mass by ?m depending on whether the previous sample failed.

Testing Principle:
At the beginning of the test, select the test method and estimate an initial mass ?m. Start testing. If the first sample fails, reduce the mass of the dropped weight by ?m. If the first sample did not fail, increase the mass of the dropped weight by ?m. Continue testing according to this rule. In short, increase or decrease the mass by ?m depending on whether the previous sample failed. After 20 samples, calculate the total number of failed samples (N). If N = 10, the test is complete. If N < 10, continue testing by adding samples until N = 10. If N > 10, continue testing by adding samples until the number of non-failed samples equals 10. After that, the tester automatically calculates the test results according to certain formulas.
