GB/T 2423.26-2008 Environmental testing for electric and electronic products—Part 2:Tests methods—Test Z/BM:Combined dry heat/low air pressure tests
Basic Information
Scope
This part of GB/T 2423 is about the high-temperature (gradual or sudden temperature change) and low-pressure comprehensive test for heat-dissipating and non-heat-dissipating 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 high-temperature and low-pressure combined environment encountered during their storage and use.
This comprehensive test is usually only used when a single environmental test of the test sample cannot reveal the impact of the combined environment. The test procedures specified in this part are only applicable to test samples that can achieve temperature stability during the test.
The test method specified in this part can only test one heat-dissipating test sample at a time.
