DIN Standards Committee Coatings and Coating Materials
Paints and varnishes - Methods of exposure to laboratory light sources - Part 3: Fluorescent UV lamps
Abstract
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.
