The current status of weathering of plastics is reviewed. As a better understanding of the effective degradative parameters of weather are obtained, it is aparent that complex interactions occur. Present laboratory exposure tests do not simulate natural conditions sufficiently to provide the much neede reliable short term exposure test for predicting long term durability. While a major step forward occurred with the introduction of filtered xwnon lamps, which simulate terrestrial sunlight both in intensity and distribution, industry‐wide support of fundamental studies of degradation is necessary if weathering studies are to be conducted scientifically.
