Plastics. Standard table for reference global solar spectral irradiance at sea level. Horizontal, relative air mass 1What is ISO TR 17801 global solar spectral irradiance at sea level about? The effect of solar radiation on the surface of the earth is the most important primary weathering factor. The photons absorbed by the molecules during radiation exposure are often sufficient to split chemical bonds, start photochemical reactions and cause an electron transfer. ISO TR 17801 provides a reference spectrum to the field of weathering degradation in order to classify
