Artificial weathering
Testing
In artificial weathering testing, samples are exposed to controlled environmental conditions with different levels of radiation, heat and irrigation.
The relative spectral irradiance of the global radiation in the ultraviolet (UV) and visible wavelength range of the spectrum is simulated using a xenon lamp.
During this test, it is possible to vary the irradiance, type of irrigation, cycles of irradiation and dark phases and the selection of optical filters.
