TEST RESULTS (Panels without steel lamination)- LEVELS 5,6,7,8
TEST
RECORD NO. 3 SAMPLES: Samples of Level 5, -Level 6, -Level 7 and -Level 8 material
rated for Level 5, Level 6,, Level 7 and Level 8, respectively, were submitted
by the manufacturer and subjected to the following test program.
BALLISTICS TEST: General - The ammunition used for the investigation was:
Level 5, Level 8 - 150 grain (9.7 g) 7.62 mm rifle lead core full metal copper
jacket, military ball, minimum velocity 2750 fps (838 mps).
Level 6 - 124 grain (8.0 g) 9 mm full metal copper jacket with lead core, minimum
velocity of 1400 fps (427 mps).
Level
7 - 55 grain (3.56 g) 5.56 mm rifle full metal copper jacket with lead core, minimum
velocity of 3080 fps (939 mps).
All
tests were conducted at close range, approximately 15 ft (4.6 m), using the ammunition
and weapon specified. The test samples were mounted in a rigidly fixed frame,
with 1/8 in. (3.2 mm) thick corrugated cardboard indicator panels placed approximately
18 in. (467 mm) behind the protected side of each test sample. During the test,
each bullet velocity was monitored and recorded.
The Level 5 samples were subjected to a 1-shot pattern. The 1-shot pattern consists
of a single shot in the approximate center of the test sample. With this shot
pattern, there shall be no penetration of the projectile through the test sample,
nor spalling of the material on the protected side of the test sample, to the
extent that fragments embed in or damage the cardboard indicators.
The Level 6, 7 and 8 samples were subjected to a 5-shot pattern. The 5-shot pattern
consists of five shots placed in a square pattern that is 4-1/2 by 4-1/2 in. (114
mm) located in the center of the test sample. With this shot pattern, there shall
be no penetration of the projectile through the test sample, nor spalling of the
material on the protected side of the test sample, to the extent that fragments
embed in or damage the cardboard indicators.
OUTDOOR
RATING(LEVEL 5 ONLY): METHOD Three samples were subjected to various ambient conditions.
One sample at room temperature, 22 ± 3C (72 ± 5F), one sample after exposure
to a temperature of 49C (120F) for a period of 3 h to the complete sample,
and one sample after exposure to -32C (-25F) to the side receiving the shots
for a period of 3 h were subjected to the 1-shot pattern. The samples were tested
immediately following the exposure to the indicated temperature conditions. The
velocity of each bullet was recorded during the test. RESULTS Acceptable results
were recorded for all shot patterns at all ambient conditions as outlined above.
