ISO 4892-2-2013 ISO 4892-2:2013 is a standard that 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 glass1. It is used to replicate weathering effects on plastic materials through the use of moisture and xenon arc light2. ISO 4892-3 is similar to this method,but it uses UV fluorescent lights as an illuminating source2.
