GB/T 2423.25-2008 Environmental testing for eletric and electronic products—Part 2:Tests methods—Test Z/AM:Combined cold/low air pressure tests
Basic Information
Scope
This part of GB/T 2423 concerns the combined low-temperature and low-pressure tests for both heat-dissipating and non-heat-dissipating test samples, as specified in clauses 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 combined low-temperature and low-pressure environments encountered during storage and use.
This combined test is typically used only when a single environmental test of the test samples fails to reveal the combined environmental impact. The test procedures specified in this part are only applicable to test samples that can achieve temperature stability during the test.
The test methods specified in this part can only be used to test one heat-dissipating test sample at a time.
