A coating system is considered to pass if there is no evidence of water-related failure after a astmm period of time. Water permeates the coating at rates that are dependent upon the characteristics of the coating and astj the temperature of the water. Knowledge on how a coating resists water immersion is helpful in predicting its service life.

Continuous overflow of the test tank is sometimes required to maintain consistent water quality. Continuous replacement of the water is permitted. It is also possible to use very large tanks for testing coated pipe or other large coated products. Results obtained from water immersion tests in accordance with this practice should not be represented as being equivalent to a period of exposure to water in the natural environment, until the degree of quantitative correlation has been established for the coating or coating system.
