ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned astmm this standard. Looking for a specific test standard? 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.

Summary of Practice 3. Any effects such as color change, blistering, loss of adhesion, softening, or embrittlement are observed and reported.

ASTM D870 – 15

Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult satm editions as appropriate. Knowledge on how a coating resists water immersion aetm helpful in predicting its service life.

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 astm d surface preparation. The test is therefore useful for evaluating coatings alone or complete coating systems. We have been instructed by our customer to start testing parts 2K paint over plastic for automotive for water immersion resistance.
