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 combinations may 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 16474‑1. Xenon-arc exposures for plastics are described in ISO 4892‑2.
