Standard Practice for Testing Water Resistance of Coatings Using Water Immersion

You are now logged in to your account. Although the apparatus and procedure could be employed in immersion tests using solutions of various materials in water, this practice is limited to tests asgm water alone. These tests typically result in a pass or fail determination, but the degree of failure may also be measured.

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. Remember me for one month.

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 aetm coating or coating system.
