Solar radiation, heat and moisture have a synergistic effect on materials and products, causing weather ageing and ultimately product failure. Weathering instruments must simulate these primary weather factors in an accelerated, precise and correlating manner.
The most advanced weathering instruments are using properly filtered xenon arc light sources. These devices are available in different geometries, sizes, and performance ranges. The weathering experimenter needs to understand the differences, operation, requirements, and parameter tolerances in order to choose the most favorable technology for his application.
