A coating system is considered to pass if there is no evidence of water-related failure after a speci? It does x870 specify specimen preparation, specific test conditions, or evaluation of results.

It does not specify specimen preparation, specific test conditions, or evaluation of results. The test is therefore useful for evaluating coatings alone or complete coating systems.

ASTM D870 – 15

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of astm d limitations prior to use. The test is therefore useful for evaluating coatings alone or complete coating systems. Register or Astmm in for direct access to additional content. The values given in parentheses are for information only.

It is also possible to use very large tanks for testing coated pipe or other large coated products. A recovery period from 12 to 24 h is generally sufficient. Knowledge on how a coating resists water immersion is helpful in predicting its service life. 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 dd870 degree of quantitative correlation has been established for the coating or coating system.

Last previous edition D — A coating system is considered to pass if there is no evidence of water-related failure after a specified period of time. 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.

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.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Although the apparatus and procedure could be employed in immersion tests using solutions of various materials astm d water, this astm d is limited s tests in water alone. Failure in a water immersion test may be caused by a number of factors including a deficiency astm d the coating itself, contamination of the substrate, or inadequate surface preparation.

A number in parentheses indicates the year of last reapproval.

Such control specimens can provide warning of changes in test severity in a given apparatus, asym can indicate variations in test severity between different apparatuses. Individual reprints single or multiple copies of this standard aastm be obtained by contacting ASTM at the above address or at phonefaxor service astm. The substrate composition and surface preparation, specimen preparation, and the number of specimens should be agreed upon prior to testing.

F Standard Specification for Driven Fasteners: 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. We have been instructed by our customer to start testing parts 2K paint over plastic for automotive for water immersion resistance. Immersion in water can cause the degradation of coatings.

ASTM D – 15 – Standard Practice for Testing Water Resistance of Coatings Using Water Immersion

Continuous overflow of the test tank is sometimes required to maintain consistent water quality. You can now freely access all or documents. 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.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations aztm to use. Our weathering, lightfastness, and corrosion experts around the world are here to help.

ASTM D – 15 Standard Practice for Testing Water Resistance of Coatings Using Water Immersion

These tests typically result in a pass or fail determination, but the degree of failure may also be measured. The test is therefore useful for evaluating coatings alone or complete coating systems. You have successfully saved to your supplier list. V870 the temperature throughout the test. Water permeates 8d70 coating at rates that are dependent upon the characteristics of the coating and upon the temperature of the water.
