29、ity of Commission Internationale del Eclairage or International Commission on Illumination Source IiCl1. The light reflected and emitted by the fluoreacent material shall be picked up with a cylindrical mirror type apparatus and shall be evaluated spectrophotometrically with the instrument using a s
30、lit width of 0.1 millimeter. The Beckman DU or DK spectrophotometers, or equivalent, may be used as the instrument for obtaining the spectral data. The light shall be measured at wavelengths specified in Table I and expressed in terms of a percentage of the light which would be reflected from the re
31、ference standard, a freshly prepared magnesium oxide surface, under similar conditions. To minimize the effects of directional reflectance, readings at two positions shall be averaged (the original sample position and a position where the sample has been rotated through 90 degrees). Reading shall be
32、 taken on the face side of the cloth specimen backed up by three thicknesses of the cloth sample to minimize differences in cloth texture and background. 4.6.2 Alternate spectrophotometric properties. The present reflectance shall be determined for the fluorescent cloth by measuring light reflected
33、and emitted at each of the following 30 wavelengths: 422, 432, 436, 439, 444, 450, 456, 461, 462, 469, 478, 489, 495, 515, 530, 541, 544, 552, 562, 564, 573, 577, 585, 589, 600, 601, 611, 624, 627, and 646 millimicrons. The measurements at 436, 461, 544, 564, 577, 589, 600, 611, 624, and 646 millimi
34、crons shall be added together. The sum shall be multiplied by 0.098. The products shall equal iiX1l. The measurements at 422, 432, 444, 450, 456, 462, 469, 478 and 495 millimicrons shall be added together. The sum shall be multiplied by 0.118. The product shall equal 11211. The measurements at 489,
35、515, 530, 541, 552, 562, 573, 585, 601 and 627 millimicrons shall be added together. The sum shall be multiplied by 0.100. The products shall equal the percent brightness IlYil of the reflected and emitted light. Dominant wavelength and purity of light reflected and emitted by the daylight fluoresce
36、nt dyed cloth shall be determined by consulting charts in the Handbook of Colorimetry, after values for X and Y are calculated with the following equations: 0 X x+Y+z Y x+Y+z - X Y - In the case of the daylight fluorescent red color, the complement of the dominant wavelength is numerically: identica
37、l with the dominant wavelength determined by the above method. 13 Licensed by Information Handling ServicesNIL-P-22655C 83 m 9999906 0473334 9 m 5.
