This part of ISO 4892 specifies methods for exposing specimens to xenon-arc light in the presence of moisture 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 window glass.<\/p>\n

Specimen preparation and evaluation of the results are covered in other International Standards for specific materials.<\/p>\n

General guidance is given in ISO 4892\u20111.<\/p>\n

NOTE Xenon-arc exposures of paints and varnishes are described in ISO 11341.<\/p>\n<\/blockquote>\n
