Sunlight, heat, and moisture act synergistically on materials, resulting in microscopic aging, visible degradation, and ultimately product failure. Laboratory weathering instruments simulate and control these primary weather factors in the "worst case".
A key question is: "How fast is my laboratory test compared to the end-use environment?" The answer is the "Acceleration Factor", which compares two given test environments, e.g. an accelerated laboratory test and a specific outdoor exposure location.
To implement the most efficient and effective testing strategy, it is critical to understand the options, limitations, and pitfalls of accelerating weather aging processes.
