MIL-STD-1660A
5.4.4.3 Impact test rationale. This test is conducted to establish that unit loads can withstand shear forces (i.e., diagonally distorting loads and other horizontal forces resulting from accelerations and decelerations suffered in transit and impacts when being handled by a crane). For additional information, see D.1 of Appendix D or E.1 of Appendix E.
5.4.5 Tipover test. This test is to be performed only if the weight and balance are such that the unit load will tip over when an edge is lifted sufficiently to form a 20-degree angle with the floor. The procedures of Appendix F shall be used. The tipover test is not required to be performed if it can be proven that the unit load will not tip at or below 20 degrees of tilt.
5.4.5.1 Tipover test rationale. This test is conducted to determine the ability of the pallet unit to maintain integrity if the unit load is tipped over during transportation. The unit load must maintain sufficient cohesion to continue to be safely handled and stacked. For additional information, see F.1 of Appendix F.
5.4.6 Forklifting test. This test shall be conducted by using the procedures of Appendix G. As an alternate procedure, the forklift hazard course shown on figure 1 may be used. Unit loads designed to use standard steel pallets do not require the pushing and towing test to be performed during qualification of the unit load.
5.4.6.1 Forklifting test rationale. This test is conducted to determine the ability of the unit load to be safely handled by forklift trucks. For additional information, see G.1 of Appendix G.
5.4.7 Pallet truck test. Unit loads, which are designed to accept pallet trucks, shall be lifted clear of the ground, transported a distance of at least fifty feet, and lowered. Tests shall be conducted four times, i.e., forks entering the pallet from each side of the load. Any tendency for unit load to be unstable while on forks, or any difficulty in inserting or removing forks, shall be cause for rejection.
5.4.7.1 Pallet truck test rationale. This test is conducted to determine the ability of the unit load to be safely handled by pallet trucks. For additional information, see G.1 of Appendix G.
5.4.8 Sling compatibility test. Unit loads utilizing special design or non-standard pallets shall be lifted, swung, lowered, and otherwise handled as necessary, using slings of the types normally used for handling the unit loads under consideration. Slings shall be easily attached and removed. Evidence of slippage or disengagement when load is suspended shall be cause for rejection of the unit load.
5.4.8.1 Sling compatibility test rationale. This test is conducted to determine the ability of unit loads utilizing non-standard pallets to be safely moved during sling lifts. For additional information, see G.1 of Appendix G.
5.4.9 Disassembly test. Following all tests, the unit load may be squared up within 2 inches of its original shape and on a flat level surface. The strapping shall then be cut and removed from the palletized load. Assembly of the load shall be such that it retains its unity upon removal of the strapping.
5.4.9.1 Disassembly test rationale. This test is conducted to determine the integrity of the assembly of the packages within a unit load and to ensure the packages are stable and adequately protected following all rough handling tests after strapping and dunnage is removed. Final inspection of pallets, bases, unit load containers, etc. ensures that no damage that would affect safety or reliability and/or other potential safety hazards is present.
5.5 Testing. Tests specified herein fulfill the test requirements of STANAG-2828 and, therefore, may be used in lieu of STANAG-2828.
5.5.1 Unitized loads of ammunition within a limited (Level C (Army)) transportation and storage cycle testing. This test is conducted to determine the ability of the unit load and its strapping, bonding, or restraint methods to withstand the stresses, shocks, and impacts likely to be incurred during temporary storage, limited transport, and typical handling. For additional information, see H.1 of Appendix H.
