Constant temperature and humidity test is an environmental simulation test method, mainly used to simulate the long-term stability of articles in a specific environment. The following is the standard specification of constant temperature and humidity test:
1. GB/T 2423.1-2008 Environmental tests for electronic products-Part 2: Test A: constant temperature and humidity test method
2. IEC 60068-2-78-1999 Environmental tests -- Part 2: Test Cab: constant humidity test method
3. ISO 2252-3-1983-Physical and chemical tests for paints and varnishes - Part 3: constant temperature and humidity test
4. ASTM D2247-11(2017) Test for water mist Resistance of coatings, paints, and lacquer surfaces
Test methods for properties of coating materials and coatings - Part 21: constant temperature and humidity drop test method
These specifications provide the specific implementation methods and required parameters of constant temperature and humidity test, which can be used to formulate test plans and judge whether the test results are qualified or not. However, the formulation of the specific test plan needs to be considered comprehensively according to the actual situation, such as the test purpose, test sample and its size.
