This Technical Report provides a reference spectrum to the field of weathering degradation (see Table 1) 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 Table 4 of CIE No. 85 .This is a realistic maximum exposure under representative clear sky conditions. The data contained in Table 1@ Figure 2@ and Figure 3 were generated using the SMARTS2 Version 2.9.2[2] [3] to recalculate the CIE No. 85@ Table 4. Table 2 contains the original data from CIE No. 85@ Table 4. The numbers are shown in Figure 2 and Figure 3 as well.
