NF EN ISO 4892-3, T51-195-3 (10/2024)

ISO 4892-3:2016 specifies methods for exposing specimens to UV fluorescent radiation, heat and water in apparatus designed to simulate the effects of aging that occur when materials are exposed to solar radiation total in actual end-use environments, or to solar radiation through window glazing. The test pieces are exposed to UV fluorescent lamps under controlled environmental conditions (temperature, humidity and/or water content). Different types of UV fluorescent lamps can be used to meet the requirements for testing different materials. Preparation of specimens and evaluation of results are covered in other International Standards for specific materials. General guidelines are given in ISO 4892-1. NOTE Exposure to UV fluorescent lamps of paints, varnishes and other coatings is described in ISO 11507.
