MIL-DTL-43191J
8/ The dimensional stability shall be performed after 1 cycle. The cloth shall not be pressed
after tumble drying prior to measurement.
9/ The needle shall measure 0.049 + 0.001 inch across the blade at the eye. The thread
for all classes shall be polyester-covered in accordance with A-A-50199, ticket no. 50, 2 ply
for the needle and ticket no. 70, 2 ply for the looper.
4.5 Methods of inspection.
4.5.1 Colorfastness evaluation testing. When testing for colorfastness properties, each color
shall be evaluated, whenever possible, separately and reported as such. In cases where the print
pattern does not allow for the evaluation of each color separately, the test results should indicated
which colors were evaluated together.
4.5.2 Spectral reflectance test. Spectral reflectance data shall be obtained from 600 to 860
nanometer (nm) for Class 3 and 6, and 700 nm to 860 nm for Class 4 and 5 on a spectro-
photometer (see 6.5) relative to a barium sulfate standard, the preferred white reference standard.
Other white reference materials may be used provided they are calibrated to absolute white; e.g.,
magnesium oxide, or vitrolite tiles. The spectral band width shall be less than 25 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 in the visible spectrum either CIE Source A or CIE Source D65. Measurements
shall be taken on a minimum of two (2) different areas and the data averaged. The measured
areas should be at least 6 inches away from the selvage. The specimen shall be viewed at an
angle no greater than 10° from normal, with the specular component included. Photometric
accuracy of the spectrophotometer shall be within 1 percent and wavelength accuracy within
2 nm. The diameter for standard aperture size used in the color measurement device shall be 1.0
to 1.25 inches in diameter for Woodland and Desert camouflage and 0.3725 inches or larger for
Universal camouflage. Any color having spectral reflectance values falling outside the limits at
four or more of the wavelengths shall be considered a test failure.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in
the contract or order (see 6.2). When actual packaging of material is to be performed by DoD or
in-house contractor personnel, these personnel need to contact the responsible packaging activity
to ascertain requisite packaging requirements. Packaging requirements are maintained by the
Inventory Control Point's packaging activities within the Military Department or Defense
Agency, or within the military service's system commands. Packaging data retrieval is available
from the managing Military Department's or Defense Agency's automated packaging files, CD-
ROM products, or by contacting the responsible packaging activity.
