Scope

This Part of GB/T 16422 provides information and general guidance relevant to the selection
and operation of the methods of exposure described in detail in subsequent parts. It also
describes general performance requirements for devices used for exposing plastics to laboratory
light sources. Information regarding performance requirements is for producers of artificial
accelerated weathering or artificial accelerated irradiation devices.
NOTE: In this Part, the term “light source” refers to radiation sources that emit UV radiation, visible
radiation, infrared radiation or any combination of these types of radiation.
This Part also provides information on the interpretation of data from artificial accelerated
weathering or artificial accelerated irradiation exposures. More specific information about
methods for determining the change in the properties of plastics after exposure and reporting
these results is given in ISO 4582.
