Abstract : This study concluded that For Level A packaging where the conditions of time and storage are unknown, corrodible military equipment must be preserved by a contact corrosion preventive compound, volatile corrosion inhibitor, or desiccant, whichever is the most feasible. Conversely, where the storage conditions are known, the need for preservation may diminish as the storage time and/or the severity of environmental conditions decrease. For desiccated packs, the use of containers or barriers with the lowest water vapor transmission rate (<0.05 grams/100 square inches/24 hours) available is required for Level A use. Again this can be modified if conditions of time and storage are known to be moderate. For non-desiccated packs, the specific inclusion of water vaporproof containers and barriers should be avoided and replaced by the more economical waterproof concontainers. This would permit the use of MIL-B- 121 barriers wherever its strength characteristics permit. Where the strength of MIL-B-121 barriers is not adequate, MIL-B-131, Class 1 barrier can be used. The use of MIL-B-131, class 1 in this case is based primarily on the strength of the barrier and not its water vapor transmission rate. (Author)
