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".
Accelerated weathering instruments come in different sizes, with different light sources and with significantly different capabilities and limitations. For certain applications, a specific technology may be preferred or often even required.
Understanding laboratory weathering technology is critical to implementing the most efficient and effective testing strategy.
This Online Seminar is the third of a 6-part series on Fundamentals of Weathering:
3) Laboratory Weathering
The other 5 parts are:
1) Factors of Weathering
2) Outdoor Weathering
4) Test Methods & Basic Standards
