Plastics. Methods of exposure to solar radiation - Intensified weathering using concentrated solar radiation Ingestion-build-207047 which is mainly regarded as1 Scope This document specifies a method for exposing plastics to concentrated solar radiation using reflecting concentrators to accelerate the weathering processes. The purpose is to assess property changes produced after specified stages of such exposures. The reflecting concentrators used in these exposures are sometimes referred to as Fresnel reflectors because in cross section the array of mirrors used to concentrate the solar radiation resembles
