Plastics. Methods of exposure to determine the wavelength dependent degradation using spectrally dispersed radiation Ingestion-build-48024 — Type 39: Double hubbed1 Scope 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.
