g.
Report the individual and average of five tests. The gel time shall meet
the requirements specified in 3.3.1.
4.8.11 Specific gravity. The specific gravity shall be determined in accordance
with ASTM D 792. Specimens shall be cut from the end of the specimens used to
determine flexural strength in 4.8.6. A minimum of five specimens shall be tested.
The specific gravity shall be as specified in 3.3.1.
4.8.12 Component distribution. The roving concentration shall be determined
on
the bare mat specimens remaining from the resin content determination of 4.8.9. The
rovings contained in the three 4 x 4 inch specimens shall be counted and recorded, and
shall conform to the requirements specified in 3.2.3.2. The chopped strand distribution
and surface mat shall be determined visually, and shall conform to 3.2.3.2.
4.8.13 Roving distribution. The roving distribution shall be determined
visually, and shall conform to 3.2.3.3.
4.8.14 Weight. The mat weight shall be determined as follows:
a.
Using the bare mat specimens from the resin content determination of
4.8.9, weigh each to the nearest 0.01 gram.
b.
Calculate the weight using the following formula:
Wm
=
0.317 Wf
Where:
Wm
=
Mat weight - ounces per square foot
Wf
=
Bare mat weight - 4 x 4 inches specimen
0.317 =
Constant for converting grams per specimen to ounces per
square foot
c.
The weight shall be as specified in 3.2.3.4.
4.8.15 Inspection of packaging. The sampling and inspection of the
preservation, packing, and container marking shall be in accordance with the
requirements of MIL-STD-1190.
