What is IEC 60068-2-78?

IEC 60068-2-78 is an international standard that defines the environmental testing requirements for electrical and electronic products. It provides guidelines for testing the performance of these products in harsh environmental conditions, such as extreme temperatures, humidity, and vibration.

Testing Procedures

The standard specifies various testing procedures to simulate different environmental conditions. These include temperature tests, humidity tests, and mechanical tests. The purpose of these tests is to assess the ability of the product to withstand the specified environmental conditions without any degradation in its performance and reliability.

Temperature Tests

The temperature tests in IEC 60068-2-78 are designed to evaluate the performance of the product when exposed to extreme temperatures. The standard defines several test methods, such as high temperature storage, low temperature storage, and cyclic temperature tests. These tests help identify any potential issues with the product's thermal resistance and determine its safe operating temperatures.

Humidity Tests

The humidity tests assess the product's ability to withstand high levels of moisture. They involve exposing the product to a controlled humidity environment for a specific duration. This helps determine if the product can function properly without any damage or deterioration in humid conditions. The standard specifies different humidity levels and test durations to simulate various real-life scenarios.

Mechanical Tests

The mechanical tests focus on evaluating the product's ability to withstand mechanical stresses and vibrations. These tests are essential for products that are subject to transportation or other forms of physical stress. The standard includes procedures for testing mechanical strength, shock resistance, and vibration resistance. By subjecting the product to these tests, any weaknesses or areas for improvement can be identified.

Overall, IEC 60068-2-78 is a crucial standard for manufacturers to ensure the reliability and durability of their electrical and electronic products. By following the testing procedures outlined in this standard, manufacturers can assess the product's performance under various environmental conditions and make any necessary improvements to enhance its quality and longevity.
