GB/T 2424.1-2015 "Environmental testing—Part 3: Supporting documentation and guidance—Cold and dry heat tests" is an important supporting and guiding document for low-temperature and high-temperature environmental testing [2-4]. It replaces the previous edition of the standard (GB/T 2424.1-2005) and is identical to the corresponding international standard (IEC 60068-3-1:2011) [2-4]. The core content of this standard is to provide detailed background explanations, technical principles, and implementation guidelines on how to correctly conduct low-temperature and high-temperature tests [4-6], such as explaining heat transfer principles, the selection of test chambers, and measurement requirements [4], to help testing personnel gain a deeper understanding of the standard and ensure the accuracy and reliability of environmental test results [2].
