3.5.2 Spectral reflectance. The infrared reflectance for the outer cover Camouflage Material, the
elastic webbing initially and after laundering shall conform to the requirements specified in
Appendix A, Tables VII, VII-A, and VII-C when tested as specified in 4.5.9. The infrared reflectance

Replace:
4.5.9 Spectral reflectance. Spectral reflectance shall be evaluated initially and after laundering as
described in GL/PD 10-07. The accelerated three laundering shall be performed using AATCC 61
Option 1A except a 4 gram sample size shall be used. When evaluating the camouflage print fabric,
each color shall be tested separately. (Note: A sample size large enough to evaluate spectral
reflectance shall be used. Ten (10) stainless spheres and 1993 AATCC Standard Reference
Detergent without optical brightener shall be used. Spectral reflectance, initially and after
laundering, shall be obtained from 600 to 860 nanometers (nm), at 20 nm intervals on an
integrating sphere spectrophometer or a spectoradiometer.
The calibration of the instrument shall be traceable to the National Institute of Standards and
Technology Perfect Reflecting Diffuser Calibration as stated in a Certificate of Traceability supplied
by the instrument calibration standards. 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. When the polychromatic mode is used, the spectrophometer shall operate
with the specimen diffusely illuminated with the full emission of a source that simulates either CIE
Source A or CIE Source D65. The Camouflage print fabric specimen Class 1 or Class 2 (see Appendix
A, Tables VII, VII-A, VII-B, and VII-C) shall be measured as a single layer backed with four layers of
the same shade. The measured areas shall be taken on a minimum of two (2) different areas and
the data averaged. The measured areas shall be taken at least 6 inches away from the selvage. The
specimen shall be viewed at an angle no greater than 10 degree from normal, with the specula
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 0.3725 inches or larger for the Camouflage Print Class 1 or Class 2
(always use the largest aperture possible). Specimens shall be oriented in different directions
during testing. When the measured reflectance values for any color at four or more wavelengths
do not meet the limits specified in 3.5.2, it shall constitute a test failure.

with the specimen diffusely illuminated with the full emission of a source that simulates either CIE
Source A or CIE Source D65. The Coyote Brown 498 fabric specimen shall be measured as a single
layer backed with four layers of the same shade. The measured areas shall be taken on a minimum
of two (2) different areas and the data averaged. The measured areas shall be taken at least 6
inches away from the selvage. The specimen shall be viewed at an angle no greater than 10 degree
from normal, with the specula 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 0.3725 inches or larger for
the Coyote Brown 498 fabric (always use the largest aperture possible). Specimens shall be
oriented in different directions during testing. When the measured reflectance values at four or
more wavelengths do not meet the limits specified in 3.5.2, it shall constitute a test failure for the
outer cover material. When the measured reflectance values at eight or more wavelengths do not
meet the limits specified in 3.5.2, it shall constitute a test failure for the elastic webbing. Objective
is all values for both outer cover material and elastic webbing fall within the wavelength
requirements.
