Finished Camouflage Green 483 webbing greater than 1 1/4 inches in width shall meet the spectral reflectance factors (in percent) for the visiblehear infrared wavelength range 600 to 860 nanometers (nm) as specified below when tested as follows. Spectr
13、al reflectance data shall be obtained fkom 600 to 860 nanometers (nm), at 20 nm intervals on the spectrophotomer relative to a barium sulfate standard, the prefered white reference standard. Other white reference materials may be used, provided they are calibrated to absolute white; e.g, Halon, magn
14、esium oxide, or vitrolite tiles. The spectral bandwidth shall be less than 26 nm at 860 nm. Reflectance measurements may be made by either the monochromatic or polychromatic mode of operation. . Whenthe polychromatic mode is used, the spectrophotometer shall operate with the specimen diffusely illum
15、inated with the full emission of the source that simulates either CIE Source A or CIE Source D65. The specimen shall be measured as a single layer, backed with two layers of the same webbing and shade. Measurements will be taken on a minimum of two different areas and the data averaged. The specimen
16、 shall be viewed at an angle no greater than 1 O from normal, with the specular component included. Photometric accuracy of the spectrophotometer shall be within one percent and wavelength accuracy within 2 nm. The standard aperture size used in the color measurement device shall be 1 .O to 1.25 inc
17、hes in diameter. When the measured reflectance values for any color at four or more wavelengths do not meet the limits specified in the chart below, it shall be a test failure.
