ISO 4892-3 塑料荧光紫外灯老化测试-标准简介

ISO4892-3规定了样品在仪器中暴露于荧光紫外线辐射、热和水的方法，该仪器用于模拟材料在实际使用中暴露于太阳辐射或通过窗户玻璃暴露于太阳辐射时产生的风化效应。样品在受控的环境条件(温度、湿度和/或水)下暴露于荧光紫外线灯下。不同类型的荧光灯可用于满足各种不同材料的测试要求。样品的制备和结果的评价在其他的国际标准中。通用指南在ISO 4892 1中给出。

ISO4892-3 specifies methods for exposing specimens to fluorescent UV radiation, heatand water in apparatus designed to simulate the weathering effects that occurwhen materials are exposed in actual end-use environments to global solarradiation, or to solar radiation through window glass. The specimens areexposed to fluorescent UV lamps under controlled environmental conditions(temperature, humidity and/or water). Different types of fluorescent UV lampcan be used to meet all the requirements for testing different materials.

Specimenpreparation and evaluation of the results are covered in other InternationalStandards for specific materials. General guidance is given in ISO 4892‑1.
