Accelerated corrosion tests are typically used to determine if a coating/substrate combination has been produced to yield a satisfactory service based on historical data from previous testing and field exposures of similar coating/substrate combinations. The intent is to find out, in a relatively short amount of time, what the appearance or performance of the product will be after several years of service. Real-life exposures are complicated events that may involve several factors including Geometric configuration, porosity/adherence of corrosion product, soiling, abrasion, fre- Quency of cleaning, cleaning procedures, cleaning chemicals, sun exposure, and temperature Variations.
