This Document 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. This Document is applicable to the specimens that 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. Specimen preparation and evaluation of the results are covered in other Standards for specific materials. General guidance is given in ISO 4892-1. NOTE: Fluorescent UV lamp exposures for paints, varnishes and other coatings are described in GB/T 23987-2009.
