There are three main factors of weather that contribute to the degradation
of exposed materials: radiant energy from the sun, temperature, and
moisture. These forces work synergistically to cause physical and chemical
changes. Understanding these factors are critical when evaluating exposed
materials, developing an exposure test program, or choosing an accelerated
method of testing. This presentation will feature specific features of
various natural and accelerated weathering test methods, discuss what
factors of weather are most accentuated by these methods, and provide a
guide to determine appropriate exposures based on the end-use application of
a material.
