This part of ISO 16474 specifies methods for subjecting coatings to UV fluorescent lamps, heat and water to reproduce, using equipment designed for this purpose, the effects of weathering that occur when end-use materials are exposed to daylight or window glass in existing environments Daylight can be used. The coatings are exposed to different types of UV fluorescent lamps under controlled environmental conditions (temperature, humidity and/or water). Different types of UV fluorescent lamps are allowed to be applied to meet all the requirements required when testing different materials. The preparation of the sample plates and the evaluation of the results are covered in other International Standards for specific materials. General guidance is given in ISO 16474-1. NOTE The exposure of plastics to UV fluorescent lamps is described in ISO 4892-3.
