SAE J2527 : Automotive Accelerated Weathering Standard

Ford / General Standards. Accelerated exposure to exterior automotive material using xenon arc lamps.

SAE J2527 tests the performance of exterior automotive 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.
