Field Corrosion Tests

Field tests show the real performance of a coated part that is exposed to all the variations in environmental conditions that cannot be simulated by laboratory tests. As with laboratory tests, the same field test procedures are applied for coating-substrate systems as for bulk materials. Evaluation is by visual inspection or surface analytical techniques. For reliable predictions of corrosion behavior, a thorough comparison of field test results with accelerated laboratory tests and electrochemical tests is indispensable.
