Drop ball impact test is a test to drop balls of specified quality from different heights, or drop balls of different quality at the specified height, so as to determine the energy required for cracks of bonding samples under the impact of drop ball. The instrument adopts standard test steel ball, which is electromagnetically hung and automatically released, which can effectively avoid the systematic error caused by human factors.
