The effect of weather on a paint is produced by natural cycling of combinations of temperature, relative humidity, wind velocity, ocean spray, precipitation, and solar radiation, to mention a few. To determine the severity of an environment on a paint and conversely the ability of a paint to give long term protection in a selected environment, the mass effect of the environmental climatic factors on the coating must be determined. No accelerated tests have proven to be sufficiently reliable to use as a basis for the prediction of performance of paints in service, especially when the paints differ considerably from each other. Outdoor exposure under conditions and climate of actual use provides the most reliable results. Where the paint use is unrestricted in regard to geography, outdoor exposure should be made in several climatic regions and at various exposure angles.
