Scope

This Part of GB/T 16422 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 light source and
various filter combinations may be used to meet different requirements.
Specimen preparation and evaluation of the results are covered in other International
Standards for specific materials.
General guidance is given in GB/T 16422.1.
NOTE. Xenon-arc exposures of paints and varnishes are described in ISO 11341.
