**A standard impact test is an experiment used to evaluate the performance and safety of a material or product under shock loads. It is widely used in military, aviation, aerospace, automotive, electronics and other fields to ensure the reliability and safety of products under extreme conditions. In the first-class standard impact test, the design and manufacture of experimental equipment need to strictly comply with national military standards to ensure the accuracy and reliability of experimental results. This article will introduce the basic principle, experimental equipment, experimental procedures and application fields of the first standard impact test.
