Plastics. Standard table for reference global solar spectral irradiance at sea level. Horizontal, relative air mass 11 Scope 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
