PRETESTER FOR WEATHER PROOF TEST

摘要

PURPOSE:To achieve accurate decision on the characteristic of deterioration by ultraviolet rays in lot-wise samples very quickly by irradiating the lot-wise samples with a very strong ultraviolet rays to promote the deterioration caused by ultraviolet rays using a water-cooled metal halide lamp before the samples are set on a weather proof (light resistance) tester. CONSTITUTION:A sample carrying base 8 is provided under a light source unit 4 housing a water-cooled metal halide lamp 2 in a reflector 3. The interval between the sample carrying base 8 and the metal halide lamp 2 is made adjustable while a sample put on the sample carrying base 8 is irradiated with ultraviolet rays with the intensity exceeding 50mW per 1cm<2>. Air is blown to the sample carrying base 8 with a blower 9 and air in the equipment is discharged with an exhaustor 10.
