feet per second for the Type I cloth, less than 1550 feet per second for the Type II cloth, less than
1250 feet per second for the Type III cloth, or less than 1300 feet per second for Type IV, or less

unacceptable if any one of the test missiles penetrates any test panel.
The sample unit for test purpose shall be as follows:
(a) Ballistic tests.
1. Types I and IA. For fragmentation resistance testing (Type I), three cuts of 15 inches
full width of the cloth with each cut originating from a different roll. For bullet resistance testing
(Type IA), six cuts of 15 inches full width of the cloth with no more than two cuts originating
from any one roll.
2. Type II. Five cuts at 15 inches full width of the cloth with each cut originating from a
different roll.
3. Types III and IV. Three cuts of 15 inches full width of cloth with each cut originating
from a different roll.
4. Type V. Seven cuts of 15 inches full width of the cloth with no more than two cuts
originating from any one roll.
(b) All end item tests excluding ballistic tests. One cut 3 yards long full width of the finished
cloth originating from one of the rolls from which the sample unit for ballistic testing was drawn.
Each individual cut comprising the sample unit shall be marked to indicate contractor's piece, lot
and roll number, and the Government lot number. The lot size shall be expressed in units of
linear yards. The sample size (number of sample units) shall be as shown in Table III. The lot
