<p>ISO 16474-4:2013 specifies methods for exposing specimens to open-flame carbon-arc lamps 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 open-flame carbon-arc light under controlled conditions (temperature, humidity and/or wetting). Different types of filters are used to simulate either direct exposure to the environment or exposure through window glass.</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. Open-flame carbon-arc exposures for plastics are described in ISO 4892‑4.</p>
