Attention Please correct the following before continuing: Failure in a water immersion test may be caused by a number of factors including a deficiency in the coating itself, contamination of the substrate, or inadequate surface preparation. The test is therefore useful for evaluating coatings alone or complete coating systems.

Q-Lab is a worldwide leader in weathering, lightfastness, and corrosion contract testing services. A coating system is considered to pass if there is no evidence of water-related failure after a specified period of time.

Corrosion tests of a scribed coating on a ferrous substrate are impractical in water immersion tests as the corrosion products tend to contaminate the water bath. Immersion in water can cause the degradation of coatings.

Significance and Use Immersion in water can cause the degradation of coatings. It is also possible to use very large tanks for testing coated pipe or other large coated products.

Standard Practice for Testing Water Resistance of Coatings Using Water Immersion

Test Standards for the QCT Condensation Tester ASTM D Standard Practice for Testing Water Resistance of Coatings Using Water Immersion This practice covers the basic principles and operating procedures for testing water resistance of coatings by the partial or complete immersion of coated specimens in distilled or de-mineralized water at ambient or elevated temperatures.

Failure in a water immersion test may be caused by a number of factors including a deficiency in the coating itself, contamination of the substrate, or inadequate surface preparation.

It does not specify specimen preparation, specific test conditions, or evaluation of results. Although the apparatus and procedure could be employed in immersion tests using solutions of various materials in water, this practice is limited to tests in water alone.

Water immersion tests are used for research and development of coatings and substrate treatments, specification acceptance, and quality control in manufacturing. 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 d80, until the degree of quantitative correlation has been established for the coating or coating system.

The test is therefore useful for evaluating coatings alone or complete coating systems. Copyright Compu-tecture, Inc.
