UL Materials Testing and Certification (English)
This method measures optical and mechanical changes induced by precisely simulated weather events. UL Solutions TTC’s controlled irradiance (CI) Xenon arc apparatus guarantees constant light intensities as well as exact temperature and humidity control. All our tests are thus carried out with the necessary reliability with regard to correlativity, precision, reproducibility and repeatability.
Compared to natural tests, this method significantly reduces the time required to calculate the light aging/weathering stability of test specimens. All important climatic factors such as radiation, heat, humidity and rain can be simulated with these devices.
Standards for Xenon-WOM
ASTM G151, ASTM G155, ISO 4892-1, ISO 4892-2, or equivalent standards
