EVS-EN ISO 4892-1:2024

ISO 4892-1 provides general guidance and requirements relevant to the selection and operation of the methods of exposure described in detail in subsequent parts of the ISO 4892 series. It also specifies 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.

Plastics are often used outdoors or in indoor locations where they are exposed to solar radiation or window-glass-filtered solar radiation for long periods. It is therefore very important to determine the effects of solar radiation, heat, moisture and other climatic stresses on the colour and other properties of plastics

ISO 4892-1 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 not part of this document. ISO 4892-1:2024 text has been approved in Europe as EN ISO 4892-1:2024 without any changes.
