This is a testing equipment that specifies the impact machine test, also known as the impact machine specification. This test is mainly used to assess the adaptability and structural integrity of electrical and electronic products on ships that are subjected to non-contact underwater explosions, airborne explosions, close range off target artillery fire, and other impact effects.

The impact conditions that shipborne electrical and electronic products may encounter during use and transportation include: local impacts caused by single and simultaneous firing of various shipborne artillery (including missiles), including shock waves from the muzzle of the artillery (also known as air wave impacts); The impact caused by the explosion of enemy shells, missiles, and aerial weapons near the ship; The non-contact underwater explosion shock caused by the explosion of self-propelled enemy attacks, such as torpedoes, mines, and depth charges, immediately below the ship's hull.
