本文件规定了将涂料暴露于荧光紫外线灯、热量和水下的方法，该装置旨在再现材料在实际最终使用环境中暴露于日光或通过窗户玻璃暴露于日光时产生的风化效应。 涂层在受控环境条件（温度、湿度和/或水）下暴露于不同类型的荧光紫外灯下。可以使用不同类型的荧光紫外灯来满足测试不同材料的所有要求。 特定材料的其他ISO文件中涵盖了试样制备和结果评估。 ISO 16474-1中给出了一般指南。 注:ISO 4892-3中描述了塑料的荧光紫外线灯曝光。

This document 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. 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 can be used to meet all the requirements for testing different materials. Specimen preparation and evaluation of the results are covered in other ISO documents for specific materials. General guidance is given in ISO 16474？1. NOTE Fluorescent UV lamp exposures for plastics are described in ISO 4892？3.
