from the same components, at the same time. The lot size shall be expressed in units of 1000 square yards of film. The sample unit shall be 6 square feet of uncoated film or 1 square foot of adhesive coated film, as applicable. The Inspection Level shall be S-1 and the AQL shall be 2.5 percent defective, for each test.
B. Examination of the end item for construction, dimensions and workmanship. Sampling shall be performed in accordance with MIL-STD-105. A lot shall consist of all envelopes of the same components, at the same time. The lot size shall be expressed in units of envelopes. The sample unit shall be 1 envelope. The Inspection Level shall be S-2 and the AQL shall be 2.5 percent defective.
C. Testing of the end item for Water Resistance and Heat-Sealed Seams. Sampling shall be performed in accordance with MIL-STD-105. A lot shall consist of all envelopes of the same size manufactured by the same process, from the same components, at the same time. The lot size shall be expressed in units of envelopes. The sample unit shall be 4 envelopes. The Inspection Level shall be S-1 and the AQL shall be 2.5 percent defective for each test.
1) Water Resistance Test. One envelope from each sample unit shall be tested for water resistance in accordance with ASTM D 951. A simulated packing list consisting of 1 sheet of 9 pound (17 x 22 – 500) manifold paper may be cut to size or sheets may taped together when necessary to make a simulated packing list of the proper size. The envelope shall be carefully sealed and the liner removed; then the envelope shall be securely fastened to a piece of wood using only the pressure sensitive adhesive on the back of the envelope. The piece of wood, with the envelope attached, shall be placed in a vertical position (90 + 100) in the test room or chamber and exposed to a medium intensity (2 + ½ inches per hour) spray of water 73.4 + 3.60 F for not less than 24 hours. Immediately after exposure to the water spray, the packing list envelope shall be examined. The envelope shall remain securely attached to the piece of wood. Drops of water shall not be present inside the envelope. The simulated packing list shall remain dry enough so that it can be completely unfolded without tearing.
2) Heat-Sealed Seam Test. Three envelopes from each sample unit shall be tested for seam strength in accordance with Method 2024 of FED-STD-101 except that 1 specimen from each envelope shall be
