WEATHERABILITY TESTING DEVICE AND WEATHERABILITY TESTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a weatherability testing device having higher correlation with an outdoor natural exposure and uniformity of deterioration processing than a conventional technique, capable of a weatherability test for simultaneously processing the deterioration in a plurality of testing object base materials, and enhancing processing reproducibility by measurement and control of a generation quantity of a radical having an oxygen atom being a deterioration promoting factor and ultraviolet radiation illuminance.;SOLUTION: This weatherability testing device has a test chamber of a vacuum atmosphere of arranging the testing object base materials inside, and has a radical generating source and an ultraviolet light source. A radiant flux of the radical having the oxygen atom and ultraviolet radiant flux are respectively separately irradiated to the testing object base materials. A sample table for placing the testing object base materials is also rotated, and the radical radiant flux and the ultraviolet radiant flux are alternately continuously irradiated to the testing object base materials. The radical generation quantity and/or the ultraviolet radiation illuminance are further controlled by making a feedback process.;COPYRIGHT: (C)2009,JPO&INPIT
