Test method of impact testing machine

General test methods for impact testing machines:
1. The test thickness was measured according to GB6672, and a point was measured at the center of all samples, and the arithmetic average of 10 samples were taken.
2. Select a punch according to the required pendulum impact energy for the test, so that the reading is between 10% DD90% of the full range
3. Calibrate the instrument according to the instrument usage rules.
4. Put the sample flat and clamp it in the clamper. The sample should not be wrinkled or the surrounding tension should be too large. The impact surfaces of 10 samples should be consistent.
5. Hang the pendulum on the release device, press the key on the computer to start the test, and let the pendulum impact the sample. The same step is to perform 10 tests. After the test is completed, the arithmetic average of the 10 samples is automatically calculated.
