1/ Except that filters shall be removed and exposure time shall be 100 hours.
2/ Except that the specimen shall be a minimum of 6 inches in any dimension.
3/ Except that the exposure temperature shall be -20o + 5oF and the exposure time shall be a
minimum of 4 hours. The face side of the specimen shall be toward the outside of the
fold.
4/ Except that the photometer shall be capable of measuring light energy over the wavelength
range of 360 to 930 nanometers.
4.4 Methods of inspection.
4.4.1 Adhesion of coating. ASTM-D-751, Adhesion of Coating with 2 inch wide reinforced
coating adhesion specimens, cyanoacrylate (solventless) adhesive, and pulling clamp speed of
5 mm/s. Three specimens shall be tested by adhering face-to face and three specimens shall
be tested by adhering back-to-back.
4.4.2 Accelerated weathering procedure. The accelerated weathering procedure shall be as
specified in either 4.4.2.1 or 4.4.2.2. The method used shall be reported.
4.4.2.1 Accelerated weathering procedure (carbon arc). Method 5804 of FED-STD-191
except that the filters shall be removed and the weathering procedure shall be as follows.
Two swatches, each 13 by 22 inches, shall be cut from the sample unit. One swatch shall be
cut with the long dimension in the direction of the warp; the other with the long dimension in
the direction of the filling. The face side of the cloth shall be exposed to the light source. The
swatches shall be exposed one above the other, in the quadrant of the accelerated weathering
apparatus for 100 hours. The swatches shall be changed from the top to bottom racks and
visa versa each time the carbons are changed (approximately 17 to 20 hours) during a 100-
hour exposure period. At the conclusion of the 100-hour exposure period, the swatches shall
be removed from the apparatus and allowed to dry and condition at Standard Conditions.
Then five specimens for the fire resistance test shall be cut from each exposed swatch such
that the direction being tested shall have been exposed to accelerated weathering in the
vertical position. In conducting fire resistance tests on these specimens, three specimens shall
be subjected to the flame at the end which was at the top of the exposed material, and two
shall be subjected to the flame at the end which was at the bottom of the specimen. The lower
edges of the fire resistance test specimens shall be trimmed, if necessary, so that a freshly cut
end is exposed to the test flame.
4.4.2.2 Accelerated weathering procedure (xenon exposure). AATCC Method 169 except
that the following deviations shall apply:
a. The test apparatus shall be either test chamber type 1A or IB. Type 1B shall be
equipped with a three-tiered inclined specimen rack. The apparatus shall be equipped with an
automatic light monitor and shall be capable of automatically controlling irradiance,
temperature, and humidity. The apparatus shall be maintained in accordance with the
manufacturer's recommendations.
