<p>ISO 4892-3:2016 specifies methods for exposing specimens to fluorescent UV radiation, heat and water in apparatus designed to simulate the weathering effects that occur when materials are exposed in actual end-use environments to global solar radiation, or to solar radiation through window glass.</p>
<p>The specimens are exposed to fluorescent UV lamps under controlled environmental conditions (temperature, humidity and/or water). Different types of fluorescent UV lamp can 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 4892‑1.</p>
<p>NOTE Fluorescent UV lamp exposures for paints, varnishes and other coatings are described in ISO 11507.</p>
