ABSTRACT:
A method of and apparatus for weather resistance test comprising a process for washing the surface of samples with a cleaner which is added at least between a process for condensing moisture on the surface of the sample after ultraviolet radiation has been applied and the process for again applying ultraviolet radiation after the process for condensing moisture. Impurities adhered to the surface of the sample and substances extracted on the surface of the sample can be removed by washing with the cleaner so that the surface of the sample to which these impurities and substances are adhered intact can be protected from being baked in the ensuing ultraviolet radiation application process. Consequently, generation of spot patterns and excessive color change of the surface of the sample can be prevented.
