17、ein. A weight exerting a force of 1 .O 2 O. 1 psi shall be placed on top of the packaging material. The weighted packaging material shall be pulled horizontally 6.0 I0.5 inches back and forth along the panel for 30 cycles at a speed of 1 foot (1 cycle) per second. The weight shall then be removed an
18、d this procedure shall be repeated using the other side of the specimen in direct contact with the same plate. 3.3.3 Low temperature flexibilitv test. 3.3.3.1 Conditioning. Cut four specimens, 4 by 12 inches, and condition for 3 hours at -20 2 2 OF. The specimens shall be arranged in a low temperatu
19、re chamber so that the air can circulate against all surfaces of the specimens. A 0.25 inch steel diameter mandrel and the test specimens shall be placed in the low temperature chamber simultaneously. 3.3.3.2 Procedure. Mer low temperature conditioning, immediately bend each specimen over the mandre
20、l so that the specimen is subjected to a 180 degree bend. Bending shall be accomplished at the conditioning temperature. The flexing operation over the mandrel shall take 2 to 3 seconds. Each specimen shall be bent over the mandrel 3 times with one face against the mandrel and then turned over so th
21、at the opposite face of the specimen is toward the mandrel; the bending procedure is then repeated as described above. 3.3.4 Vibrational settling test. 3.3.4.1 Cleated plywood box. A cleated plywood box conforming to PPP-B-601, Style A (except as specified herein) shall be fabricated. The box shall

No cover is necessary. 3.3.4.2 Prototype load. A rigid prototype test load shall be fabricated of wood, stee
23、l, aluminum, or other rigid materials. In order to provide a 100 square inch bearing area on the packaging material, the prototype test load shall have length and width dimensions of 1 O by 1 O inches with a -0.0625 tolerance for each. The prototype shall be constructed in such a manner that the loa
24、d-bearing surface is flat. The prototype load shall be designed so that its weight provides a bearing stress of O. 1 O f 0.01 psi. In addition, an accelerometer shall be mounted to the prototype load. 3.3.4.3 Pack assembly. The inside bottom surface of the cleated plywood box shall be covered with 1
25、00 f 5 grams of the packaging material to be tested. 3.3.4.4 Test Drocedure. Place the completed pack upon a vibration table in the configuration shown on figure 1. Place the prototype test load on the test specimen and immediately vibrate the entire test xture at O. 5 Gs through a frequency sweep o
26、f 5 Hz to 1 O0 Hz (vertical linear) at a rate of 2 octaves/minute. Note the fiequency at which resonance occurs (natural frequency).
