Testing shall be as specified in 4.3.4 of PR97-03-12.
8/ The cloth for the front panels of the load-bearing vest shall be a nylon rachel knit cloth. The cloth shall weigh not more than 11.5 ounces
per square yard, have a thickness of not more than 0.05 inch, a minimum bursting strength of 325 pounds, a minimum breaking strength of
350 pounds in the wale direction and 200 pounds in the course direction, and a minimum tearing strength of 25 pounds in both directions. The
cloth shall have a maximum shrinkage of 7.5 percent in both directions, a maximum ultimate elongation of 95 percent in the wale direction and
140 percent in the course direction, and a minimum stiffness (load-pounds) of 0.010 in the wale direction and 0.010 in the course direction. A
non-durable acrylic finish shall be used to meet the stiffness requirements. The color of the cloth shall be Olive Drab 107. The finished cloth
shall show "good" fastness to light, laundering, and crocking.
9/ The webbing used as shoulder straps of the LBV shall be 3 ½ inches in width, have a thickness of .036 (min), a fabric count (min.) 420
warp, 48 fill, 20 binders, weight 1.90 oz per ln yard (min), a break strength (min) 5,000 lb. For Spectral Reflectance requirements see Table
IV of PR97-03-12.
10/ The metal grommet for drain holes shall be plain with toothed washer. The grommet shall be made of brass and have a dull black finish.
The finish shall be produced by chemical or electrochemical treatment. Black finished surfaces shall be thoroughly rinsed free of treatment
chemicals. The finish shall completely hide the color of the underlying material. The dimensions of the finished grommet and washer shall be
as shown on Figure 5 of PR97-03-12.
11/ The metal eyelets with washers shall be brass and have a dull black chemical finish suitable for copper alloys. The brass for the eyelets
shall be annealed suitable for forming. Brass of the flat washers shall be tempered, minimum half-hard. The finished eyelets and washers shall
be free from fracture, malformation, burrs and rough or sharp edges. Washers shall be smooth and free of any bend. The finish shall be free of
foreign imbedded matter and discoloration, and provide complete coverage of the eyelets and washers. Eyelet metal shall not crack when
clinched. The eyelet size in inches shall be as follows: 0.200 + 0.004 bottom outside diameter, 0.403 + 0.007 overall outside diameter, 0.143 +
0.008 or 0.210 + 0.008 (to be determined by the contractor) effective shank length, and 0.013 + 0.0015 thickness. The washer size in inches
shall be as follows: .220 + .002 diameter of hole, .450 + .003 overall diameter, and .020 + .004 - .002 thickness.
12/ The hook and loop pile fastener tape shall be 1 + 1/16 inch wide, 8.0 mil hook (330 denier) nylon tape. The hook tapes shall be of woven,
warp pile, narrow fabric construction, with multifilament ground ends (including selvages), and picks. Monofilament auxiliary warp ends shall
be woven in the form of raised loops which can be heat set to retain their shape and cut near the top of the loop in order to form a free hook
engaging section. The hooks shall be leno woven in a staggered order. The hook tapes shall have a minimum of 191 hooks and 51 picks per
linear inch, a minimum of 174 ground ends per tape (including selvage), and a minimum of 30 hook ends per tape. The hook tapes shall have
a minimum weight of 5.9 grams per linear yard, a minimum breaking strength of 125 pounds, a minimum shear strength of 15.0 pounds, and a
minimum thickness of 0.050 inch. The loop pile tapes shall be of woven, warp pile, narrow fabric construction, with multifilament ground ends
(including selvages) and picks, with leno woven ends. The loops shall be suitably napped to form a uniformly disoriented surface of uncut
loops capable of being engaged by the hooks of the hook tape component, or, as an alternate, shall be woven of specially treated loop pile
yarns that provide a uniformly disoriented surface without being napped. The loop pile tapes shall have a minimum of 51 picks per inch, a
minimum of 149 ground ends per tape (including selvages), and a minimum of 28 loop pile ends per tape. The loop pile tapes shall have a
minimum weight of 7.4 grams per linear yard, a minimum breaking strength of 95 pounds, a minimum shear strength of 15.0 pounds, and a
minimum thickness of 0.095 inch. The color of the hook and loop pile tapes shall be Camouflage Green 483. The dyed tapes shall show
fastness to laundering and crocking equal to or better than the standard sample. When no standard sample is available, the dyed tapes shall
show good fastness to laundering and crocking. All hook and loop pile tapes shall be stabilized to allow for maximum flatness and dimensional
stability. In addition, the tapes shall be coated with a suitable polymeric or elastomeric undercoating.
13/ All slide fasteners shall be individual element plastic chain with minimum of 220 lb. crosswise breaking strength, overall closed chain
width of 0.435 inch (nominal) and minimum single element pull-off strength of 40 lb. with water repellent treated tape, color black for sliders,
chain and tape. Two sliders in throat-to-throat configuration with pulls (short or long) having holes large enough to allow a thong and ¼-inch
diameter padlock to lock the slider pulls together. A 5-6-inch nylon black thong shall be attached to each pull. As an optional pull, a padlock
pull that can accommodate a ¼-inch diameter padlock is acceptable. (Note: Plastic continuous element coil chain cannot be used in horizontal
stress design configuration).
