国际标准化组织 11341:2004 provides a method for determining the resistance of coatings and painted surfaces to artificial weathering and exposure to artificial radiation using filtered xenon arc radiation sources. This standard applies to coated and painted surfaces intended for external exposure.

This standard sets out general principles for testing procedures, including selection of test samples, preparation of test samples, exposure conditions and evaluation of test results. Exposure conditions include irradiance, 温度, 相对湿度, and spectral power distribution of xenon arc sources.

Exposure tests involve exposing the test sample to a cycle of radiation and moisture in a controlled laboratory environment. The standard provides two different exposure procedures: Procedure A covers exposure to radiation and moisture, and Procedure B covers exposure to radiation, 湿度和温度.
