What is the IEC 60068 Shock Test?

The International Electrotechnical Commission (IEC) 60068 shock test is a standardized procedure used to assess the ability of electronic and electrical equipment to withstand mechanical shocks. It is an important test that helps ensure the reliability and durability of products in various industries, including aerospace, automotive, and consumer electronics.

Shock Test Procedure

The IEC 60068 shock test simulates the effects of sudden and intense mechanical impacts that can occur during transportation, handling, or operation of the equipment. The test involves subjecting the device under test (DUT) to controlled and predefined shocks in different directions and magnitudes.

The test starts by mounting the DUT onto a vibration machine or shock table. This machine generates a rapid acceleration or deceleration which causes a sudden impact on the DUT. The shock wave generated is measured using an accelerometer, which detects the intensity and duration of the shock event.

The shocks are applied based on a series of predefined shock pulse shapes and durations specified by the IEC 60068 standard. These pulses simulate common types of mechanical impacts, such as those caused by dropping the equipment, sudden collision, or rough handling during transit.

Evaluating Test Results

After subjecting the DUT to the shock test, the test results are evaluated against predetermined criteria. These criteria may include the functionality of the equipment, any visible damage, and changes in performance characteristics. Functional tests may be performed immediately after the shock test or after a certain period to assess any delayed effects of the shocks.

If the DUT passes the shock test without any significant damage or performance degradation, it indicates that the equipment is capable of withstanding the mechanical shocks expected in its intended environment. This gives manufacturers confidence in the product's reliability and helps them meet regulatory requirements or customer specifications.

However, if the DUT fails the shock test, it may signify potential design flaws, weak points in the construction, or inadequate packaging. Failures can lead to product recalls, increased warranty claims, and possible harm to users due to malfunctioning equipment.


The IEC 60068 shock test plays a crucial role in ensuring the robustness and reliability of electronic and electrical equipment. By subjecting the devices to controlled mechanical shocks, manufacturers can identify and rectify any weaknesses in their products, leading to improved quality and durability. Ultimately, this test is essential in enhancing customer satisfaction by delivering products that can withstand the rigors of real-world use.
