What is IEC 60068 Part 2-14?

IEC 60068 Part 2-14, also known as Environmental testing - Part 2-14: Tests - Test N: Change of temperature, is an international standard developed by the International Electrotechnical Commission (IEC). It specifies a method for testing electronic and electrical products to evaluate their ability to withstand temperature changes.

The Purpose of IEC 60068 Part 2-14

The main purpose of IEC 60068 Part 2-14 is to ensure that electronic and electrical products can perform reliably in various temperature environments. This standard helps manufacturers understand how their products will respond to extreme temperature conditions and assists in determining the suitability of the product for specific operating environments.

Testing Procedure

The testing procedure outlined in IEC 60068 Part 2-14 involves subjecting the product to a series of temperature changes within predefined limits. The product is typically placed in a test chamber where the temperature is raised and lowered according to a specified pattern. This pattern may include ramp rates, hold times, and dwell periods. The purpose of these temperature changes is to simulate real-world scenarios and assess the product's performance under different thermal stress conditions.

Test Results and Evaluation

After completing the test, the results are evaluated based on predefined criteria. These criteria may include functional operation, physical damage, or any other specific requirements depending on the nature of the product. The evaluation process considers factors such as temperature variation, time response, and the ability of the product to recover its functionality after exposure to extreme temperatures. Based on these evaluations, the product can be certified for compliance with the standard or rejected if it fails to meet the specified criteria.
