Gives a reference spectrum to the field of weathering degradation in order to classify solar simulators in the UV, visible and infrared wavelength range.

This Technical Report provides a reference spectrum to the field of weathering degradation (see Table1) 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. To give a spectral irradiance target, the table specifies the spectral irradiance of global radiation (direct and diffuse radiation) with a cloudless sky, zenith position of the sun by day and night comparisons at the equator at sea level as defined in Table4 of CIE No.85.This is a realistic maximum exposure under representative clear sky conditions.

The data contained in Table1, Figure2, and Figure3 were generated using the SMARTS2 Version 2.9.2^[2][3] to recalculate the CIE No. 85, Table4.

Table2 contains the original data from CIE No. 85, Table4. The numbers are shown in Figure2 and Figure3 as well.
