The Durable CASS Test 730210

The neutral salt spray as an accelerated corrosion test to predict the service performance of decorative, bright-plated automobile trim gave such unsatisfactory results that the American Electroplaters' Society sponsored development of more rapid and reliable testing methods. The Corrodkote and CASS tests were successfully developed to duplicate the extent and type of corrosion occurring on parts in one winter's service in Detroit. It is suggested that unsatisfactory experience with the neutral salt spray as an accelerated test was due to failure to define service performance properly, and that the CASS test has proved to be more satisfactory mainly because performance criteria have been more realistically defined.
