Accelerated weathering is something that hastens the natural process by which an item decomposes. Paint manufacturers use accelerated weathering to test paints used for decorating buildings. These tests typically involve applying the paint to be tested to a small panel which is then placed in a revolving drum and subjected to alternating ultra-violet light - to simulate the effects of sun light - and soaking with jets of cold water - to simulate the effect of rain. In such a test several month's normal outdoor exposure can be simulated in a few days. Research Accelerated Weathering
