MIL-DTL-43976D
3/ Three gloves shall be selected from each sample unit and one specimen shall be tested from each
glove selected. Method A of the test shall be used.
4/ The specimen shall be aged at 212oF for 48 hours in accordance with ASTM Method D 573 before
being tested for tensile strength and elongation.
5/ Refers to test method in MIL-STD-282.
*4.4.6 Packaging examination. The fully packaged end items shall be examined for marking,
materials, workmanship and content defects.
4.5 Methods of inspection.
*4.5.1 Thickness test. Thickness of the gloves shall be in determined in accordance with
Method 2011 of FED-STD-601. Three gloves from each sample unit shall be tested. Five
measurements shall be made on each of the three gloves in an area of not less than 1 inch nor more than
5 inches from the cuff edge. The crotches of the gloves shall also be measured for thickness. The
sample unit shall fail if any single measurement is less than the minimum specified. If any measurement is
greater than the maximum specified, determine the size of the area that is over the maximum thickness.
If it is greater than one inch in diameter, the sample unit shall fail. If it is less than one inch in diameter
and equal to the maximum thickness allowable for a localized area, the sample unit shall pass. If it is less
than one inch in diameter and greater than the maximum thickness allowable for a localized area, the
sample unit shall fail.
*4.5.2 Porosity.
*4.5.2.1 Test apparatus. The test apparatus shall be of a mechanism as described herein or
any other similar type in principle, provided the results can be obtained as specified in 4.5.2.2. A
hollow wooden shank, 3 inches in length, tapered on the outer surface to fit the open end of a rubber
glove and a steel ring tapered on the inner surface to fit over the wooden shank shall be used. The
shank shall be attached to a steel base plate to make an airtight joint, and the tapered ring shall be
bolted to the base plate so that it can be tightened over the shank. The brass nipple shall be connected
with the other pipe fittings to mount a tire inflation valve, an air pressure gauge and a pressure release
valve. The assembled apparatus shall be as shown in Figure 2.
*4.5.2.2 Procedure. The cuff of the glove shall be pulled over the shank of the test apparatus
and clamped firmly in place by tightening the steel ring against the base plate. Compressed air shall be
fed into the glove to a pressure of 0.5 pound per square inch for types I and II gloves and 0.25 pound
per square inch for type III gloves. The inflated glove shall be immersed in the water for stages, for
observation of porosity as indicated by air bubbles. The inflated gloves shall be immersed into the water
cuff or fingers first in three stages. Initially the glove shall be immersed so that about 1/3 of the glove is
under water. The glove will be care fully observed for air bubbles. If no air bubbles are seen the glove
shall be lowered until 2/3 of the glove is under water. Again, carefully observe the area under water for
air bubbles. If no air bubbles are observed the remainder of the glove shall be immersed so that the tip
of the middle finger or cuff bead is less than 1 inch below the water line. Carefully observe the
glove for air bubbles. No visible bubbling shall be permitted during the test. At no time should
the area of the glove being observed for air bubbles be further than 6 inches below the surface of the
water. The pressure exerted by the water below this 6-inch depth can be great enough to prevent the
release of air bubbles from a small hole or tear.
