Abstract

Blue Scale has been used as the standard test sample for evaluation of color fastness to daylight ( JIS L 0841 ), ultraviolet carbon arc lamp light ( JIS L 0842 ), and xenon arc lamp light ( JIS L 0843 ). The importance of this Scale is recently increasing not only in textile field but also in other various fields. Capability and reproducibility of this Blue Scale have been already enough explored, however, its spectral characteristics and action spectrum have not yet enough investigated.<br>In this research, the color fading behavior of Blue Scale by 9 kinds of fluorescent lamps ( 20W ) having different spectral distribution was quantitatively investigated. <br>As the results, the relation between the fading and the wavelength was clearly recognized on the scales less than 3rd grade. The principal wavelength of radiation which cause the fading were 525nm and 610nm for 1st grade scale, 352nm, 525nm and 610nm for 2nd grade scale and 352nm for 3rd grade scale. In case of grading the samples by comparing with Blue Scale under 3rd grade, it should be noted that tendency of the grading is different according to the spectral composition irradiated by light sources.
