The values given in parentheses are for information only. 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.
E Standard Guide for Strategic Warehousing. Remember d for one month. Practices D covers application techniques for the production of uniform? Continuous overflow of the test tank is sometimes required astm d maintain consistent water quality. Knowledge on how a coating resists water immersion is helpful in predicting its service life. Maintain the temperature throughout the test.
Originally published as D — 46 T. 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 astm d degree of quantitative correlation has been established for astm d coating or coating system.
Enter your personal account email address to request a password reset: A coating system is considered to pass if there is no evidence of water-related failure after a specified period of wstm. This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version.
Ashm does not specify specimen preparation, speci? Last previous edition D — Any effects such as color change, blistering, loss of adhesion, softening, or embrittlement are observed and reported.
Continuous overflow of the test tank is sometimes required to maintain consistent water quality. Link to Active This link will always route to the current Active version of the standard. F Standard Specification for Driven Fasteners: If you feel that your comments aastm not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
It is also possible to use very large tanks for testing coated pipe or other large coated products. It does not specify specimen preparation, specific test conditions, or evaluation of results. A recovery period from 12 to 24 h is generally sufficient.
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 d8770 environment, until the degree of quantitative correlation has been established for the coating or coating system.
The substrate composition and surface preparation, specimen preparation, and the number of specimens should be agreed upon prior to testing. These tests typically result in a pass or fail determination, but the degree of failure may also be measured. Knowledge on how a coating resists water immersion is helpful in predicting its service life.
The test is therefore useful for evaluating coatings alone or complete coating systems. You can now freely access all or documents.

A coating system is considered to pass if there is no evidence of water-related failure after a specified period of time. Protect the edges and backs of the specimens from corrosion if these surfaces are not to be tested.
ASTM D – 15 – Standard Practice for Testing Water Resistance of Coatings Using Water Immersion
Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. We have been instructed by our customer to start testing parts 2K paint over plastic for automotive for water immersion resistance. Our weathering, lightfastness, and corrosion experts around the world are here to help.
Please correct the ashm before continuing: Rate specimens for changes in color, blistering, etc. It is also possible to use very large tanks for testing coated pipe or other large coated products.
