Paints and varnishes. Methods of exposure to laboratory light sources - Xenon-arc lamps best-seller What is BS EN 48141 Scope This part of ISO 16474 specifies methods for exposing specimens to xenon arc light in the presence of moisture to reproduce the weathering effects that occur when materials are exposed in actual end use environments to daylight or to daylight filtered through window glass. The specimens are exposed to filtered xenon arc light under controlled conditions (temperature, humidity and or wetting). Various types of xenon arc lamps and various filter
