Ultraviolet exposure (UV testing) is performed to understand how a material will withstand the damaging effects of ultraviolet exposure, which can cause significant changes to the properties and useful life of a material.
Prolonged exposure to UV rays can cause a host of issues, including fatigue and reduction of strength, yellowing or discoloration, cracking, brittleness, and general deterioration. To combat this, UV testing simulates the sun’s ultraviolet rays in a controlled laboratory setting.
Ultraviolet exposure & UV testing programs allow labs to test for prolonged periods of exposure in a fraction of the time. Because of the variety of environmental factors involved in real-world scenarios, it is advisable to avoid attempts to correlate laboratory UV testing with specific time frames of real word aging. However, labs can provide comparative data for multiple materials to evaluate overall resistance to UV aging.
