1 Scope
This part of ISO 4892 specifies methods for exposing specimens to xenon-arc light in the presence ofwindow moisture glass. to reproduce the weathering effects (temperature, humidity and/or wetting) that occur when materials are exposed in actual end-use environments to daylight or to daylight filtered through Specimen preparation and evaluation of the results are covered in other International Standards for specific materials. GeneralNOTE guidanceXenon-arc is exposuresgiven in ISO of paints4892-1. and varnishes are described in ISO 11341.
