This paper describes the accelerating test method for the soiling caused by flowing rain containing dirt. 1) The color changes of materials caused by flowing rain containing dirt were observed by rainy day exposure test. And the influence of flowing rain on soiling was clarified. 2) An apparatus for accelerating the soiling process caused by flowing rain containing dirt was developed and appropriate testing conditions of the apparatus were clarified based on the similarity of the results to the exposed materials. 3) The relation between accelerating test cycles and the environmental factors became clear. 4) The color difference between soiled material and unsoiled initial material had a correlation with the psychological scale obtained from a sensory test about soiling.
