And another way, by exposed to sunlight (in the glass case), discoloration of wood are estimated and compared with the results of accelerate discoloration tests. Brief results were as follows. 1) As for the lightness L, specimens became darker and darker. 2) Chromaticness increased in accordance with the test going, and test pieces turn to yellowbrown. 3) Discoloration of wood by exposure test undergo faster than that of the accelerate test. 4) Result of the continuous Fade-meter test for 10 days can forecast the discoloration of wood by exposed "Underglass" in the two months of June and July (Tokyo).
