What is the IEC 60068-2 vibration test?

The International Electrotechnical Commission (IEC) has established several standards to ensure the reliability and performance of electronic and electrical equipment. One such standard is the IEC 60068-2 vibration test, which evaluates the ability of a device to withstand mechanical vibrations. This article aims to provide an easy-to-understand explanation of this technical test.

Why is the IEC 60068-2 vibration test important?

In real-world scenarios, electronic and electrical equipment can experience various types of vibrations during transportation, usage, or environmental conditions. Excessive vibrations can lead to failure or malfunction, causing significant losses in terms of financial costs and safety risks. Therefore, it is crucial to subject these devices to vibration testing to ensure their reliability and durability.

How does the IEC 60068-2 vibration test work?

The IEC 60068-2 vibration test involves subjecting the device to controlled mechanical vibrations. The equipment under test is securely mounted on a vibration test system that simulates different vibration profiles, including sinusoidal, random, and mixed-mode vibrations. The test system generates vibrations with specific frequencies, amplitudes, and durations. The device's response to these vibrations is then analyzed to determine its resistance to mechanical stress.

What are the parameters evaluated in the IEC 60068-2 vibration test?

The IEC 60068-2 vibration test assesses various parameters of the equipment. These include its ability to withstand certain frequency ranges, amplitudes, and acceleration levels. Additionally, the test evaluates the device's structural integrity, component reliability, and performance stability during and after the vibration exposure. The test results help manufacturers identify design flaws or weaknesses, allowing them to improve the product's robustness.
