ISO 4892-3 塑料熒光紫外燈老化測試-標(biāo)準(zhǔn)簡介
ISO 4892-3規(guī)定了樣品在儀器中暴露于熒光紫外線輻射、熱和水的方法，該儀器用于模擬材料在實(shí)際使用中暴露于太陽輻射或通過窗戶玻璃暴露于太陽輻射時產(chǎn)生的風(fēng)化效應(yīng)。樣品在受控的環(huán)境條件(溫度、濕度和/或水)下暴露于熒光紫外線燈下。不同類型的熒光燈可用于滿足各種不同材料的測試要求。樣品的制備和結(jié)果的評價(jià)在其他的國際標(biāo)準(zhǔn)中。通用指南在ISO 4892 1中給出。

ISO 4892-3 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. The specimens 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 International Standards for specific materials. General guidance is given in ISO 4892?1.
