GB/T 2423.26-2008 Environmental testing for electric and electronic products.Part 2 Test methods TestZ/BM:Combined dry heat/low air pressure tests (English Version)
This part of GB/T 2423 is about the comprehensive test of high temperature (gradual or sudden temperature change) and low air pressure of heat dissipation and non-radiation test samples, see 8.2.2 and 8.2.8. The purpose of this test is to determine the adaptability of components, equipment and other products to the comprehensive environment of high temperature and low pressure encountered in their storage and use. This comprehensive test is usually only used when the single environmental test of the test sample cannot indicate the comprehensive environmental impact. The test procedures specified in this section apply only to test samples that can achieve temperature stabilization during the test. The test methods specified in this section can only test one heat dissipation test sample at a time.
