v (15c) (1) Behavior of paint films when exposed to natural weather or accelerated weathering equipment, characterized by changes in color, texture, strength, chemical composition, or other properties. Natural outdoor weathering tests are normally carried out at selected exposure sites, on painted panels, generally exposed either vertically or at 45° facing south in the northern hemisphere. See  Accelerated Weathering. (2) The process of disintegration and decomposition as a consequence of exposure too the atmosphere, to chemical action, and the action of frost, water, and heat. (3) A broad term encompassing exposure of plastics to solar or ultraviolet light, temperature, oxygen, humidity, snow, wind, and air-borne dust and biological or chemical agents, such as smog.
