PLASTICS - METHODS OF EXPOSURE TO SOLAR RADIATION - PART 3: INTENSIFIED WEATHERING USING CONCENTRATED SOLAR RADIATION (FIRST REVISION) (ISO 877-3:2009, IDT)
This Malaysian Standard 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. General guidance concerning the scope of ISO 877 is given in ISO 877-1:2009, Clause 1. 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 the cross-section of a Fresnel lens.
