Abstract

Immersion testing is the most frequently conducted test for evaluating corrosion of metals in aqueous solutions. This article focuses on the basic factors that are considered in different conditions of immersion testing. These factors are solution composition, temperature, aeration, volume, velocity, and waterline effects; specimen surface preparation; method of immersion of specimens; duration of test; and method of cleaning specimens. The article discusses the different conditions of immersion testing, namely, full immersion condition, high temperature condition, partial immersion and vapor phase condition, and alternate immersion condition. It concludes with a checklist of items that should be included in a standard report of immersion tests.
