The Importance of Solar Exposure Testing
Applied Technical Services performs solar exposure testing to support clients who need to verify whether their materials and components resist the weathering effects of sunlight as appropriate to their final product’s anticipated service conditions. Consumers have long noted how years of sunlight exposure can affect their household products, even if they never consciously drew the connection; the vibrant colors of lawncare tools’ coatings fade, vinyl car interiors crack, and plastic outdoor furniture becomes brittle and loses that glossiness it initially had. The segment of the electromagnetic spectrum that the sun naturally generates — namely infrared (IR), ultraviolet (UV), and visible light waves — weathers materials over time, causing adverse aesthetic and structural changes. The sun’s other characteristic emission, heat, also prematurely ages plastic products.
