The publication covers wooden pallet designs, styles, construction features, pallet sizes, and general, special-purpose, expendable, ammunition, and missile pallets. It also specifies palletized load thresholds, weight limits, NATO shipment requirements, air-shipment considerations, and storage aids.
Applies to: This pamphlet serves as a guide to Army shippers in the selection of pallets for shipment and storage of materiel.
The amount of materiel to be loaded on a pallet will exceed either a total of 250 pounds (excluding the pallet) or a volume of 20 cubic feet and will compactly occupy at least 80 percent of the pallets load bearing surface. (paragraph 1-4)
The maximum weight limit for palletized unit loads is 3,000 pounds for domestic, intercoastal, or overseas shipments. Ammunition unit loads are limited to a maximum weight of 4,000 pounds. Palletized unit loads to North Atlantic Treaty Organization (NATO) forces should not exceed 2,500 pounds, except ammunition from the United States and United Kingdom which can be 4,000 pounds. (paragraph 1-4)
When using expendable type pallets, no overhang is permitted beyond the perimeter of the pallet deck. (paragraph 1-4)
The ideal pallet size for shipping and storing general supplies is 40 inches by 48 inches. (paragraph 3-3)
Nonstandard pallet sizes will be permitted for palletization only where general supply items are too large to fit the 40inch by 48-inch pallet. (paragraph 3-3)
