Attention: Mr. George Smith

Gentlemen:
In accordance with your verbal authorization, H.P. White Laboratory, Inc. conducted Ballastic Resistance Testing of two fiberglass laminates identified as ARMORCORE which were received on 13 November 1997 via United Parcel Service.

Testing was conducted in accordance with the Level II-A requirements of NIJ-STD-0108.01, BALLISTIC RESISTANT PROTECTIVE MATERIELS, dated September 1985. The test samples were rigidly mounted on an indoor range 16.5 feet from the muzzle of a test barrel to produce zero degrees obliquity impacts using calibers 9mm, 124.0 grain, FMJ and .357 Magnum, 158.0 grain, JSP ammunition. Lumiline screens were positioned at 6.5 and 9.5 feet which, in conjunction with an elapsed time counter (chronograph), were used to determine velocities at 8.0 feet from the muzzle. Penetrations were determined by visual examination of a 0.020 inch thick sheet of 2024T3 aluminum positioned 6.0 inches behind, and parallel to, the test samples. The requirements of NIJ-STD-0108.01 specify only that the shot pattern will be “evenly spaced”. Integrating that requirement with a minimum allowable sample size of 12" x 12", we have dereived a shot pattern of 5 shots on the corners and in the center of an 8.0 inch square. In order to eliminate variance in the test REGUARDLESS of the size of the test sample. Table I is a summar of the attached data records.
