The cyclic condensation test chamber is a general condition and procedure for testing coated specimens in a constant or alternating condensation environment to ensure reproducibility of test results between different laboratories. It can simulate three humid environments: CH (condensation environment under constant humidity), AHT (condensation environment under alternating air temperature and humidity), and AT (condensation environment under alternating air temperature), reflecting the degree of corrosion and defect types of coatings under different environmental conditions.
