Plastics - Methods of exposure to laboratory light sources - Part 2: Xenon-arc lamps (First revision) (ISO 4892-2:2006, AMD. 1:2009, IDT)
This Malaysian Standard specifies methods for exposing specimens to xenon-arc light in the presence of moisture to reproduce the weathering effects that occur when materials are exposed in actual end-use environments in daylight or daylight filtered through window glass.
The specimens are exposed to filtered xenon-arc light under controlled conditions (temperature, humidity and/or wetting). Various types of xenon-arc light source and various filter combinations may be used to meet different requirements.
Specimen preparation and evaluation of the results are covered in other International Standards for specific materials.
General guidance is given in ISO 4892-1.
NOTE: Xenon-arc exposures of paints and varnishes are described in ISO 11341.
