What is IEC 60068-31:2007?

IEC 60068-31:2007 is an international standard that defines the test methods to determine the resistance of electronic components and equipment to vibration. This standard provides guidance on testing procedures, test levels, and acceptable criteria for evaluating the performance of products when subjected to various types and levels of vibrations.

Vibration Testing Procedures

The standard specifies two main types of vibration tests: sinusoidal vibration and random vibration. Sinusoidal vibration tests subject the equipment to a single frequency at a time, while random vibration tests apply vibration with a wide range of frequencies simultaneously.

During the tests, the equipment is typically mounted onto a vibration platform or table. The vibration is then applied in different directions (i.e., x, y, and z-axis), and the product's performance is evaluated based on its ability to withstand these vibrations without malfunctioning or sustaining damage. Test parameters such as frequency, amplitude, and duration are defined in the standard.

Test Levels and Acceptable Criteria

IEC 60068-31:2007 provides guidelines for determining appropriate test levels based on the intended use environment of the equipment. These test levels simulate real-world scenarios that the product may encounter, such as transportation or operation in harsh conditions.

The standard also outlines acceptable criteria for evaluating the product's performance during and after vibration testing. These criteria often include factors like functional operation, visual inspection, and electrical performance. By comparing the test results against the predefined acceptance criteria, manufacturers can ensure that their products meet the required quality and reliability standards.

Benefits and Importance

The implementation of IEC 60068-31:2007 brings several benefits to manufacturers and end-users. Firstly, it allows manufacturers to assess and improve their product designs by identifying potential weaknesses that may affect the equipment's performance under vibration. This helps in developing more robust and reliable products.

For end-users, the standard provides a means to compare various products and evaluate their resistance to vibration. By using products that meet the criteria defined in IEC 60068-31:2007, they can be confident about the reliability and durability of the equipment in their specific applications.

In conclusion, IEC 60068-31:2007 is a vital international standard for assessing the resistance of electronic components and equipment to vibration. By following the prescribed test methods, manufacturers can ensure the quality and reliability of their products, while end-users can make informed decisions based on the compliance of the equipment with this standard.
