ISO 4892-3 : general accelerated weathering standards
Plastics method of exposure to laboratory light source.
ISO 4892 specifies methods of exposing samples to laboratory light sources with the addition of moisture, humidity, and temperature, to simulate the conditions which it is expected to endure in its real-life application.
For ISO 4892-3, specimens are exposed to fluorescent UV lamps under controlled environmental conditions (temperature, humidity, and/or water). Different types of fluorescent UV lamps may be used to meet all of the requirements for testing different materials.
