Environmental testing Part 2: Test methods Test N: Temperature variation range The tests specified in this part of GB/T 2423 are used to determine the ability of components, equipment, or other products to withstand rapid changes in environmental temperature. The exposure duration at each temperature required to achieve this depends on the characteristics of the test sample. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document. IEC 60068 (all parts) Environmental testing IEC 60068-2-1-Environmental testing, Part 2-1: Test methods: Test A: Low temperature (Environmental testing Part 2-1: Tests Test A: cold) IEC 60068-2-2 Environmental testing Part 2-2: Test methods: Test B: High temperature (Environmental testing Part 2-2: Tests Test B: dry heat) IEC 60068-2-17 Environmental testing Part 2-17: Test methods, Test Q: Sealing The preparation of safety publications and the use of basic safety publications and group safety publications are common in electronic devices and components. When the device is not powered on, its internal parts undergo slower temperature changes than the parts on its external surface
