- How should items that require Method 52 preservation be packaged?
MIL-STD-2073 states, 'The item, preserved, wrapped, cushioned and desiccated as required in accordance with 18.104.22.168, shall be enclosed in a close fitting
inner container (box) selected from Table C.I. The item and container shall then be enclosed in a sealed bag conforming to MIL-DTL-117, Type I, Class E, Style 1; or Type III, Class E, Style 1.
When specified in the contract or purchase order, a designated bag, other than noted herein, shall be furnished. Bags in
accordance with MIL-E-6060 shall be used when the construction limitations of MIL-DTL-117 are exceeded. The sealed bag shall then be enclosed within an appropriate outer
container (box) selected from Tables C.I or C.II. When fiberboard outer containers are used, they shall conform to the weather resistant Class and Grade of ASTM-D5118 or
ASTM-D5168 as applicable. When wood, wood cleated plywood or wood cleated fiberboard, paper overlaid veneer, etc., boxes are specified as the outer container, a 6 mil
polyethylene film conforming to A-A-3174 or equivalent material shall be used as an overwrap (tape sealed) around the sealed bag to prevent chafing or rupture by the outer
When the primary cushioning is located between the sealed bag and the outer container, the barrier protective wrap specified herein is not required. Closure sealing
or banding (as applicable) shall be in accordance with the applicable container specification procedures or ASTM-D1974, making certain that the bag is not damaged. (Note: When
the outer container becomes the shipping container, it shall be marked as a shipping container in accordance with MIL-STD-129: the bag shall be marked as a unit pack in accordance with MIL-STD-129.)'
