At GPT we can perform a large array of accelerated weathering including Xenon, Fadeometers Exposures (Single Arc and Twin Arc), and Sunshine XW Carbon Arc all with automatic temperature and humidity control, and variable light, dark, and water cycles. Post exposure evaluations can include visual color evaluations according to AATCC or ISO Gray Scale, Instrumented Colorimetry Evaluations, gloss, haze, and microscopic evaluations.
New to weathering? Our guide What Is Accelerated Weathering Testing? explains how xenon arc and carbon arc exposures work, how interior and exterior methods differ, and which OEM specifications apply.
