Paints and vanishes - Methods of exposure to laboratory light sources - Part 1 : general guidance
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. ISO 16474-1:2013 also provides information on the interpretation of data from artificial accelerated weathering or artificial accelerated irradiation exposures.

<p>ISO 11507:2007 specifies exposure conditions for paint coatings exposed to artificial weathering in apparatus including fluorescent UV lamps and condensation or water spray. The effects of weathering are evaluated separately by comparative testing of chosen parameters.</p>
<p>ISO 11341:2004 specifies a procedure for exposing paint coatings to artificial weathering in xenon-arc lamp apparatus, including the action of liquid water and water vapour. The effects of this weathering are evaluated separately by comparative determination of selected parameters before, during and after weathering. </p> <p>The standard describes the most important parameters and specifies the conditions to be used in the exposure apparatus.</p>
