Abstract

This part of ISO 4892 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 window-glass filtered solar radiation. The specimens are exposed to radiation from fluorescent UV lamps under controlled environmental conditions (temperature, humidity and/or water). Different types of fluorescent UV lamps 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. NOTE Fluorescent UV lamp exposures for paints, varnishes and other coatings are described in ISO 16474-3.
