Astm d 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. A recovery period from 12 to 24 h is generally sufficient. The test is therefore useful for evaluating coatings alone or complete coating systems.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

Last previous edition D — 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. 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.

A coating system is considered to pass if there is no evidence of water-related failure f870 a specified period of time. Astm d tests typically aatm in a pass or fail determination, but zstm degree of failure may also be measured.

The apparatus for the test is relatively inexpensive and can be as simple as a glass beaker with a stirrer.
