What is ISO/TR 17801 - global solar spectral irradiance at sea level about?
The effect of solar radiation on the surface of the earth is the most important primary weathering factor. The photons absorbed by the molecules during radiation exposure are often sufficient to split chemical bonds, start photochemical reactions and cause an electron transfer. ISO/TR 17801 provides a reference spectrum to the field of weathering degradation in order to classify solar simulators in the UV, visible and infrared wavelength range. The photochemical ageing which occurs in practice is simulated with time compression in laboratory weathering instruments by sequencing maximum stress climate episodes.
