The standard specifies an accelerated test method for simulating the effects of acidic atmospheric precipitation on coatings. The standard describes the Acid Dew and Fog (ADF) test, which simulates the effect of acid precipitation by artificial acid precipitation and ultraviolet radiation, condensation precipitation, temperature, and Humidity changes. The test is designed to evaluate the suitability of coatings in acidic environments, rather than fully simulating actual outdoor efflorescences. This method provides more uniform damage and faster test results than in natural environments, helping to predict the performance of coatings under acidic precipitation conditions in the laboratory.
