Immersion Corrosion Tests:

Immersion tests can take the following forms:

Relatively simple tests involving constant immersion. The acceleration of corrosion damage can be achieved from the length of immersion in the corrosive medium and other accelerating factors.
Tests involving alternate immersions/drying in the form of cyclical tests.
Instrumentation of test specimens during immersion (such as connections to electrochemical instrumentation) to facilitate measurements other than simple weight loss measurements.
From simple beaker type tests to immersion of flush mounted coupons in flow loops to simulate service conditions more closely.

Historically, immersion tests have been extensively used to generate uniform corrosion data for alloys used in the process industries under immersion conditions.
