Over the past several years, the Bureau of Reclamation’s Materials Engineering Research Laboratory has been developing and refining a test method to evaluate a coating’s resistance to erosion damage in sediment-laden immersion exposure. This test has initially been utilized as a screening/ranking method in selection of new coatings for the aforementioned severe service environments. However, the goal is to develop the procedure into an ASTM standard test method. This paper details the procedure developed by Reclamation in collaboration with the ASTM standards committee and provides initial results from several coating types.

Weight loss is measured during extended testing in order to evaluate and compare coating wear over time. It is expected that this standard will be useful in selection of coatings intended for raw water immersion service, particularly in situations where there are entrained solid particulates present in flowing water.
