MIL-DTL-81997D
4.3.1 Sampling for conformance inspection. For the purpose of determining the sample size
in accordance with ASQC-Z1.4, the lot size (see 6.3) shall be expressed in number of pouches
produced in one production run and shall use an inspection level of S-1 for testing and S-3 for
visual examination.
4.4 Visual examination of end item for defects in materials, construction, closure,
dimensions and tolerance, identification, and sealing recommendations. The sample unit for the
end item visual inspection shall be one pouch. The sample unit shall be visually inspected and
measured to ensure it meets the requirements specified in 3.2, 3.3, 3.3.1, 3.4, 3.5, 3.8, and 3.9.
4.5 Seam continuity test. Water containing a dye such as methyl violet shall be poured into
the pouch so that the water solution will cover an entire side of the pouch when laid on its side.
The pouch shall be closed with a supplemental final heat seal or by closing the zipper closure, as
applicable. Manually hold the pouch in a vertical attitude. Rotate the bag 360° in 90°
increments so that each sealed edge is on the bottom for thirty seconds. Dye leakage through any
original heat seal or the zipper closure indicates failure to meet the seam continuity requirement.
4.6 Heat-sealed seam test. Heat-sealed specimens shall be tested in accordance with the heat-
sealed seam test specified in MIL-STD-2073-1, Appendix G, using a static load of 2-1/2 pounds.
The number of specimens to be tested from each pouch shall be reduced when the size of the
pouch precludes testing the prescribed number of specimens.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in
the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-
house contractor personnel, these personnel need to contact the responsible packaging activity to
ascertain packaging requirements. Packaging requirements are maintained by the Inventory
Control Point's packaging activities within the Military Service or Defense Agency, or within the
military service's system commands. Packaging data retrieval is available from the managing
Military Department's or Defense Agency's automated packaging files, CD-ROM products, or
by contacting the responsible packaging activity.
