Accelerated UV Weathering Device Based on Integrating Sphere Technology



Joannie W. Chin, E Byrd, E Embree, Jason D. Garver, B Dickens, T Finn, Jonathan W. Martin


An accelerated ultraviolet (UV) weathering device based on integrating sphere technology has been designed, fabricated, and implemented in weathering studies of polymers. This device has the capability of irradiating multiple speciments with exptremely uniform, high intensity UV radiation and simultaneously subjecting them to a wide range of precisely-controlled temperature and relative humidity. This paper will describe the integrating sphere-based weathering system, its ability to precisely control temperature and relative humidity, and ability to produce a highly uniform UV irradiance
