Plastics — Methods of exposure to solar radiation — Part 3: Intensified weathering using concentrated solar radiation

SKU: 5b34e49a31b7 Category:

Description

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 the cross-section of a Fresnel lens.

General guidance concerning the scope of the ISO 877 series is given in ISO 877-1.

NOTE            Additional information about solar concentrating exposures, including a partial list of standards in which they are specified, is given in the Bibliography.
