artificial weathering

SAE J2527

accelerated exposure of exterior automotive material using xenon arc lamps

SAE J2527 tests the performance of samples inside a Q-LAB Xe-3 Xenon Arc Chamber. Samples are exposed to Xenon Arc light, accelerating the simulation of the outdoor environmental conditions. This allows us to recreate the effects of direct sunlight, temperature and/or moisture.
