3.8.4 Spectral reflectance test. Spectral reflectance data for all specified Solid colors (Style A) or printed camouflage colors (Style B, C, and D) shall be determined on the face side and shall be obtained from 600 to 860 nanometers (nm) at 20 nm intervals on a spectrophotometer relative to the polytetrafluoroethylene (PTFE) family of compounds, the preferred white standard. Other white reference materials may be used provided they are calibrated to absolute white or vitrolite tiles. The spectral band width shall be less than 20 nm at 860 nm. Reflectance measurements shall be made by either the monochromatic or polychromatic mode of operation. When the polychromatic mode of operation is used, the spectrophotometer shall operate with the specimen diffusely illuminated with the full emission of a continuous source that simulates either CIE Source A or CIE Source D65. The specimen shall be measured as a single layer only on the loop fastener tape. Measurements shall be taken on a minimum of two (2) different areas and the data averaged. The specimen shall be viewed at an angle no greater than 10° from normal, with the specular component included. Specimens shall be oriented in different directions during testing.

Camouflage materials (Style B, C, and D) should be measured with the appropriate aperture size to ensure that only one (1) color is measured at a time. The diameter for standard aperture size used in the color measurement device shall be 1.0 to 1.25-inches for most solid colors and 0.3725-inches for the UCP, OEF-CP, and OCP (always use the largest aperture possible).

Photometric accuracy of the spectrophotometer shall be within one (1) percent and wavelength accuracy within 2-nm. Any color having spectral reflectance values falling outside the limits at four (4) or more of the wavelengths specified shall be considered a test failure. NOTE - For Operation Enduring Freedom Camouflage Pattern (OEF-CP) and Operational Camouflage Pattern (OCP), all color evaluations shall be performed on the solid color area and not the tonal area.

3.9 Finish.

3.9.1 Finish (Type I, Type II and Type IV only). All hook and loop fastener tapes shall be stabilized as necessary to allow for maximum flatness, fray resistance (see 3.11), and dimensional stability.
