In recent years, the application scenarios of electrical and electronic products have become increasingly perse worldwide. The impact of climatic environmental tests on the performance of related products has attracted much attention, and formulating scientific and reasonable environmental test plans has become an important step to ensure product quality and reliability.

IEC has attached great importance to the construction of the International Electrotechnical Commission Quality Assessment System for Electronic Components (IECQ), and released IEC 60068-3-14:2025, Environmental testing—Part 3-14: Supporting documentation and guidance—Developing a climatic sequential test. It is the first IEC standard led by China in the field of environmental testing, providing a generic process for developing a climatic sequential test programme by sequencing test methods prescribed in the IEC 60068-2 series.
