NF EN ISO 11507

<p>ISO 16474-1:2013 provides information and general guidance relevant to the selection and operation of the methods of exposure described in detail in subsequent parts. It also describes general performance requirements for devices used for exposing paints and varnishes to laboratory light sources. Information about such performance requirements is required only by producers of artificial accelerated weathering or artificial accelerated irradiation devices.</p> <p>ISO 16474-1:2013 also provides information on the interpretation of data from artificial accelerated weathering or artificial accelerated irradiation exposures.</p>

<p>ISO 16474-3:2013 specifies methods for exposing coatings to fluorescent UV lamps, heat and water in apparatus designed to reproduce the weathering effects that occur when materials are exposed in actual end-use environments to daylight, or to daylight through window glass.</p> <p>The coatings are exposed to different types of fluorescent UV lamps under controlled environmental conditions (temperature, humidity and/or water). Different types of fluorescent UV lamp 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 ISO documents for specific materials.</p> <p>General guidance is given in ISO 16474‑1. Fluorescent UV lamp exposures for plastics are described in ISO 4892‑3.</p>
