What is IEC 60068-2-78?

IEC 60068-2-78 is an international standard that specifies the testing method for both high and low temperature. Specifically, it outlines a procedure for testing electronic components and equipment to assess their ability to withstand extreme temperatures. The standard provides guidelines for determining the effects of these temperatures on the performance, reliability, and functionality of the tested products.

Scope and Objective

The primary objective of IEC 60068-2-78 is to ensure that electronic devices and equipment can operate reliably and safely within specified temperature ranges. This standard helps manufacturers, engineers, and other stakeholders to assess the suitability of their products for various environmental conditions.

This specific test method focuses on the behavior of products exposed to both high and low temperatures. By subjecting electronic components or equipment to extreme temperatures, potential issues such as component failure, degradation of parameters, or malfunctioning can be identified early in the development cycle.

Testing Procedures

The testing procedures prescribed by IEC 60068-2-78 involve exposing the electronic equipment to temperatures outside their normal operating range. The temperature levels are determined based on the intended application and environmental conditions in which the product is expected to function.

The standard specifies the time duration for which the equipment needs to be subjected to high and low temperatures. This enables engineers to evaluate how the temperature cycle affects the performance, functionality, and structural integrity of the tested product.

During the testing process, different parameters such as electrical continuity, insulation resistance, voltage, and mechanical aspects are measured to assess the impact of temperature extremes. The results of these tests help manufacturers make informed decisions regarding the quality, reliability, and durability of their products.

Conclusion

IEC 60068-2-78 plays a crucial role in ensuring the reliability and functionality of electronic equipment under extreme temperature conditions. By following the testing methods outlined in this standard, manufacturers can identify potential issues early in the development process and make necessary improvements to enhance the quality and performance of their products.

Ultimately, compliance with IEC 60068-2-78 helps to create a safer and more reliable electronic environment for users.
