Over the years, traditional methods for testing and screening materials which are prone to corrosion have suffered from chronic complaints about the lack of acceleration. Efforts to respond to this criticism have included changes in laboratory cyclic test chambers and outdoor test methods. This paper examines the performance of a specific coating system after cyclic exposure to seven different accelerated corrosion test methods, two of which are South Florida Test Service test designs.
Of the seven accelerated corrosion test methods reviewed, the ones that provided the fastest corrosion growth after a total of 4 weeks of exposure are: cyclic salt fog and cyclic salt spray. It is also possible to achieve significant corrosion growth by conducting outdoor cyclic corrosion tests in the Arizona desert.
