Zusammenfassung:	PURPOSE:To enable accurate control of the test temperature of a sample regardless of changes in the ambient temperature, by blowing air to the sample while the temperature of the sample portion is detected with a sensor to adjust the blow. CONSTITUTION:A sample 3 is placed on a sample mount 4 in a testing tank 1 and light of an artificial light source 2 in a lamp house 5 is made to irradiate a sample through a reflecting mirror 6 to test for the deterioration in the sample. In the test, air is blown directly to the sample 3 through a blow-off nozzle 8 from a blower 7 to adjust the temperature of the sample. The heated air is discharged outside a testing tank 1 with an exhaust fan 9. On the other hand, the blow of the blower 7 is controlled through an inverter 13 by an output of a temperature sensor 12 connected to a black panel 11 set on the sample mount 4 to maintain the test temperature of the sample 3 at a specified value.
