Please correct the ashm before continuing: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. A coating system is considered to pass if there is no d8870 of water-related failure after a specified period of time.
Significance and Use Immersion in water zstm cause the degradation of coatings.
Search entire listing of all standards. F Standard Specification for Driven Fasteners: It does not specify specimen preparation, specific test conditions, or evaluation of results.
Continuous overflow of the test tank is sometimes required to maintain consistent water quality. Remember d for one month. Test Standards for the QCT Condensation Tester ASTM D Standard Practice for Testing Water Resistance of Dd 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. Q-Lab is a worldwide leader in weathering, lightfastness, and corrosion contract testing services.

These tests typically result in a pass or fail determination, but the degree of failure may also be measured. 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 asmt been established for the coating or coating system.
