MIL-DTL-43976D
NOTE: During porosity testing involving the types II and III gloves, it may become necessary to
assist in immersing the gloves by supporting them with the manipulating hand.
4.5.3 Low temperature stiffness test. Low temperature stiffness shall be
determined in accordance with ASTM D 1053, paragraph entitled "Routine Inspection and
Acceptance" with the following exceptions:
The test shall be conducted at 40oF
a.
b.
The liquid coolant shall be methyl alcohol.
c.
The exposure time shall be 5 minutes.
d.
The black wire having a torsional constant of 0.125 gf. cm/degree shall be
used instead of the standard wire.
e. The angular degree of twist shall be in accordance with 3.3.1.
4.5.4 Deformation due to decontamination solution test. Three gloves from each sample
unit shall be tested. The resistance to decontamination solution shall be determined as follows:
a. Accurately mark a 3 by 6 inch area on each glove. Draw three straight lines along the entire
length of the area as follows: The first line shall be ½ inch in from one edge of the marked area, the
second line ½ inch in from the opposite edge. The third line shall be 1-1/2 inches from both edges.
Then draw three straight lines across the entire width of the area as follows: The first line shall be 2
inches in from one edge of the marked area, the second line 2 inches in from the opposite edge. The
third line shall be 3 inches from both edges. Using a micrometer as described in Method 2011 of FED-
STD-601, determine the thickness of the area at the nine points where the three length lines cross the
three width lines. The thickness shall be the average of the nine values.
b. Mount the glove on a suitable form and immerse in test solution to within 1 inch of the cuff
edge, taking care not to wet the interior. The test solution shall be a super-tropical bleach (STB) slurry.
The slurry shall be made up (by weight) of 1 part super-tropical bleach conforming to MIL-D-12468
and 2 parts water. (Note: Super-tropical bleach is corrosive to most metals and is injurious to most
fabrics. A protective mask and gloves should be worn when handling this material.) The temperature of
the slurry during the test shall be 80o to 90o F. The time of immersion shall be 5 minutes.
c. After the 5 minute immersion in STB solution, withdraw the glove, wash off the slurry with
water, then rinse in 95% ethyl alcohol and, while the glove is still wet, measure the marked area
immediately for thickness and length. Thickness shall be determined as described in "a" above. The
length shall be measured along the three length lines and the length recorded as the average of the three
measurements.
d. Place the wet gloves on heavily talked paper towels and allow to stand at room temperature
for 18 hours.
e. After the 18 hours air-drying, remeasure the marked area for thickness and length.
Determine thickness in accordance with "a" above and length in accordance with "c" above.
f. The percent increase in thickness and percent increase in length shall be calculated as follows:
% increase in thickness after immersion (wet)
=
T1-T x100
T
% increase in thickness after immersion & aeration
=
T2-T x100
