Test method of impact testing machine

Select a punch according to the required pendulum impact energy for the test, so that the reading is between 10% DD90% of the full scale
2. Measure the test thickness according to GB6672, measure a little at the center of all samples, and take the arithmetic average of 10 samples tests.
3. Calibrate the instrument according to the instrument usage rules.
4. Hang the pendulum on the release device, press the button 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.
5. 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.
