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 TableĀ 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 TableĀ 4 of CIE No.85.This is a realistic maximum exposure under representative clear sky conditions.
The data contained in TableĀ 1, FigureĀ 2, and FigureĀ 3 were generated using the SMARTS2 Version 2.9.2[2][3] to recalculate the CIE No. 85, TableĀ 4.
TableĀ 2 contains the original data from CIE No. 85, TableĀ 4. The numbers are shown in FigureĀ 2 and FigureĀ 3 as well.
