Plastics. Methods of exposure to solar radiation - Direct weathering and exposure behind window glass1 Scope This part of ISO 877 specifies a method for the direct exposure of plastics to solar radiation (method A) and a method for the exposure of plastics to glass filtered solar radiation (exposure behind window glass) (method B). 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.
