Plastics — Methods of exposure to determine the wavelength dependent degradation using spectrally dispersed radiation

This document specifies methods of determining the spectral response of all kind of plastics materials to ultraviolet and visible radiation by an irradiation test with spectrally dispersed irradiation. NOTE Typical specimens that are evaluated include: films, liquids, plaques, pellets, powders, sheets and discs.
