Diffuse reflection as a feature of dyed coatings is important characteristic regarding camouflage protection analysis. In our laboratory practice, the need for diffuse reflection analysis of textile materials has appeared, recently. Therefore, astm e903-12 [1] method has been modified in order to be applicable for this type of materials. The measurements of diffuse reflection were conducted, in the military technical institute laboratory for textile, leather and shoes examination in belgrade, serbia, using the uv/vis/nir spectrophotometer uv 3600 from a japanese manufacturer shimadzu with an integrating sphere within wavelength area from 650 nm to 1000 nm. For the purpose of results analyses, uv probe programme package [2] was used. 10 measurements of spectralon (manufactured by labsphere®), which is used as a certified reflectance standard, were performed and obtained standard deviation was 0.07 %. Then control sample, a piece of a standard military cloth of serbian army, which has fi...ve color shades (light green, beige green, dark green, brown and black) was tested. Standard deviations were in range from 0.09% for black tone on 650 nm wavelength to 2.0% for light green tone on 1000 nm. The combine uncertainty for the method was ±2.0 %, which coincides with the above mentioned astm standard. In the end, comparative measurements of the same control sample for all five shades were performed in the “vinca” institute for nuclear sciences, department for physical chemistry, university of belgrade on lambda 35 perkin-elmer uv/vis/nir spectrophotometer. Moreover, the z score was calculated as well, and its values ranged from -0.71 to +0.71, which was satisfying regarding interlaboratory measurements rules. Overall results showed that this method is applicable for diffuse reflection measurements of textile materials.
