GB/T 2423.4-2008 is designed for evaluating the suitability of components, equipment, or other products when they are subjected to high humidity and temperature cycling conditions, which typically result in condensation on the surface of the test sample. This test method is particularly relevant for assessing the performance of products during transportation and storage. If the sample is packaged, the test should be conducted together with the packaging to ensure accurate results.
For small or lightweight samples, it may be challenging to induce condensation on the surface. In such cases, users are advised to consider alternative testing methods, such as GB/T 2423.34-2005, which provides a different approach for temperature and humidity cycle testing.
The standard references several normative documents, including:
- GB/T 2421-1999: General principles for environmental testing of electrical and electronic products
- GB/T 2422-1995: Terminology for environmental testing of electrical and electronic products
- GB/T 2423.34-2005: Test methods for environmental testing of electric and electronic products – Part 2: Test Z/AD: Temperature/humidity combination cycle test
- GB/T 2423.6-2006: Performance confirmation of temperature/humidity test chambers for electrical and electronic products
