Abstract
The performance of the three methods of accelerated corrosion tests, i. e., CASS, Corrodkote, and SO2 tests must be in accordance with the following items.
(1) Similarity of corrosion defects in outdoor exposure tests.
(2) Accelerating properties in outdoor exposure tests.
(3) Reproducibility of the test results.
At first, the effects of the thickness of electroplated coatings under various corrosive atmospheres on the results of outdoor exposure tests were studied.
These three tests were carried out in view of comparing their characteristics in the above items (1) and (2).
The test revealed that CASS and SO2 tests gave remarkably excellent results in the above items (1) and (2), and in respect to operation and expense.
