<p>ISO 16474-2:2013 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 to daylight or to daylight filtered through window glass.</p>
<p>The specimens are exposed to filtered xenon-arc light under controlled conditions (temperature, humidity and/or wetting). Various types of xenon-arc lamps and various filter combinations may be used to meet all the requirements for testing different materials.</p>
<p>Specimen preparation and evaluation of the results are covered in other International Standards for specific materials.</p>
<p>General guidance is given in ISO 16474‑1. Xenon-arc exposures for plastics are described in ISO 4892‑2.</p>
