What is IEC 60068-26vibration resistance?

Vibration is a common phenomenon in many industrial processes and can cause significant damage to equipment and products. To ensure the reliability and durability of electrical and electronic devices, international standards have been developed to define vibration resistance requirements. One such standard is IEC 60068-26, which specifies the testing methods and criteria for vibration resistance. In this article, we will explore the basics of IEC 60068-26 vibration resistance and its importance in various industries.

The Importance of Vibration Resistance

Vibration resistance is crucial in ensuring the proper functioning and longevity of electrical and electronic equipment. In industries where machines and equipment are subject to vibrations, such as automotive, aerospace, and manufacturing, failure due to vibrations can lead to severe consequences, including safety hazards, production downtime, and monetary losses. By adhering to IEC 60068-26, manufacturers can assess the performance of their products under simulated vibration conditions and make necessary design improvements to enhance reliability.

Testing Methods and Procedures

IEC 60068-26 defines the testing methods and procedures to evaluate the vibration resistance of electrical and electronic equipment. The standard outlines various test levels, each specifying specific vibration patterns, amplitudes, and durations. These tests can be conducted using mechanical shakers or by subjecting the equipment to real-world vibration sources encountered during transportation or operation. The performance of the equipment is evaluated based on its ability to withstand these vibrations without any significant degradation or failure.

Criteria for Vibration Resistance Assessment

To determine whether a product meets the requirements of IEC 60068-26, several criteria are evaluated during the testing process. These include measuring changes in electrical parameters, physical damages or failures, performance degradation, and functional error rates. The equipment is subjected to vibration in multiple axes and frequencies to replicate real-world conditions. Test results are then compared against predetermined limits and standards to assess the product's overall vibration resistance.
