It is done to determine the structural strength and weak points of the design under the dynamic loads to which the sample is exposed under real working conditions.

Shock testing of products is a critical testing procedure performed to evaluate their physical and functional durability against potential force impulses and temperature changes in handling, transportation and service environments. This testing determines how products respond to relatively infrequent, short-term and moderately high-level force impulses, accelerations or decelerations, and temperature changes.

Mechanical shock testing usually involves subjecting a tester to sudden and extreme acceleration or deceleration. This testing is performed using instruments such as strain gauges, load cells, piezo sensors. The purpose of the test is to measure how the device handles these situations. Multi-channel data acquisition systems use this sensor data to produce waveforms, spectrum representations, and documentation. Engineers then analyze the recorded response, determine performance and make improvements.
