ABSTRACT:
An optical deterioration-accelerating weather and optical resistance testing device has a light source and a frame supporting a sample to be tested rotating around the light source. Thermal deterioration of the sample due to radiant heat generated by the light source is inhibited by the provision of a cold air guide enclosing a portion of the sample rotating frame on which the sample is supported. Cold air is introduced to the surfaces of the sample through the cold air guide to maintain the both sides of the sample at a constant test temperature.
