Plastics. Standard table for reference global solar spectral irradiance at sea level. Horizontal, relative air mass 1
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.
