The basic stresses in weathering are known and quantified. The time a material is stressed and the temperature during UV and water stresses are the primary variables in natural weathering. Reproducing them exactly in the laboratory can provide acceleration by eliminating idle time. Further acceleration is possible by maximizing UV, water and temperature stresses within natural limits. The tests reported here indicate that the most important factor in accelerated laboratory weathering is the proper balancing of these stresses.
