Abstract

PURPOSE:To improve correlativity with deterioration in the natural world by almost equalizing a wavelength-energy distribution curve obtained by integrating the light intensity and irradiation time of monochromatic light projected on a sample relatively to the distribution curve of the sunshine. CONSTITUTION:The sample is held in a holder moving on an arcuate rack fixed along positions where the monochromatic light with a 200-700nm wavelength range in a test room 3, and the holder is controlled by a control part. For example, light intensity S320 of the sunshine of 320nm per unit time is 0.2W/m<2>/nm and the light intensity I32 of the testing device per unit time is 14W/m<2>/nm; when th light is projected for a time T320, the intensity is m=70XT320 times as large as when the sunshine is projected for the unit time and Tn is so determined that m=InXTn/Sn is constant with each wavelength value, thereby conducting a test equivalent to the intensity (m) times the light intensity of the sunshine per unit time over the entire wavelength range.
