This document describes the test methods for accelerated outdoor exposure of building materials and components, including black box exposure test, Fresnel otoscope accelerated sunlight exposure test, outdoor periodic spray exposure test, Fresnel otoscope accelerated sunlight exposure/freeze-thaw cycle test. It is suitable for evaluating the performance changes of building materials and components under accelerated atmospheric environment conditions. According to the characteristics of different materials, different test methods should be selected for evaluation. The environmental conditions of the exposure test field should be selected to represent typical environmental conditions of climatological types or typical environmental conditions that are consistent with the actual environmental conditions of the tested product and are relatively stable.
