What is the IEC 60068-21 procedure?

The IEC 60068-21 procedure is an internationally recognized standard that specifies a testing method for assessing the ability of electronic equipment to withstand the effects of condensation. This procedure helps in determining the reliability and performance of such equipment under varying environmental conditions.

Understanding the purpose of the IEC 60068-21 procedure

The primary objective of the IEC 60068-21 procedure is to evaluate the resistance of electronic equipment to condensation. Condensation can occur when there is a significant temperature difference between the environment and the equipment, causing moisture accumulation on the surface. This moisture can potentially damage the electronic components or interfere with their proper functioning.

The procedure involves subjecting the equipment to controlled temperature changes while maintaining constant humidity levels. The test aims to simulate real-world scenarios where devices may be exposed to high humidity levels as a result of changes in temperature or surrounding conditions.

Test conditions and criteria

The IEC 60068-21 procedure outlines specific conditions and criteria for conducting the tests. These include controlling the relative humidity levels, applying cycles of temperature changes, and monitoring the behavior and functionality of the equipment throughout the process.

During the test, the equipment is typically placed in a chamber where temperature and humidity can be controlled. It undergoes several cycles of temperature changes, including rapid and gradual variations. The equipment's performance and functionality are observed during and after each cycle to determine any adverse effects caused by condensation.

The criteria for passing the test depend on the type of equipment and intended application. These criteria may include parameters related to insulation resistance, mechanical integrity, electrical safety, and other specific requirements outlined in the standard.

Benefits of compliance with IEC 60068-21

Compliance with the IEC 60068-21 procedure offers several benefits for manufacturers and users of electronic equipment. By subjecting their products to this test, manufacturers can ensure that their equipment meets international standards of reliability and quality.

For end-users, the compliance indicates that the equipment will perform effectively even in environments where condensation may occur. It provides confidence in the durability and functionality of the devices under varying conditions, reducing the risk of costly failures or performance degradation.

Overall, the IEC 60068-21 procedure serves as a vital benchmark for assessing the ability of electronic equipment to withstand the effects of condensation. Its implementation helps both manufacturers and users in ensuring the reliable performance of electronic devices in diverse environmental conditions.
