Drop resistance test at low temperature. The plastic container shall be placed in a fiberboard shipping container (overpack). The plastic container shall be filled to 98 percent of capacity with liquid which is compatible with polyethylene and will remain liquid at 9°F. The filled shipping container shall then be sealed as for shipment and conditioned for 24 hours at 04F. Immediately after conditioning, the sealed shipping container shall be dropped from height of 48 inches onto a steel, concrete, or stone surface of sufficient mass to absorb the shock without deflection so that the corner of the shipping container absorbs the full force of the fall. This test shall be repeated on top and bottom and on two other sides of the shipping container. The fall shall be a free fall, in that no ropes or other suspending media are attached to the shipping container during the fall.
Drop resistance test at room temperature. The plastic container shall be placed in a fiberboard overpack and shall be filled to 98 percent capacity with water. The filled shipping container shall then be sealed as for shipment and conditioned for 24 hours at 75o + 5oF. The sealed shipping container shall then be subjected to the same drop test as described in the low temperature drop test.
Drop resistance test at high temperature. The plastic container shall be placed in a fiberboard overpack. The plastic container shall be filled to 98 percent of capacity with water. The filled shipping container shall then be sealed as for shipment and conditioned for 72 hours at 92.5 + 2.5 percent relative humidity at a temperature of 125o + 5o F. The sealed shipping container shall then be subjected to the same drop test as described in the low temperature drop test.
Wet strength test, fiberboard overpack. The plastic container shall be placed in a water-resistance wax-resin-impregnated box, grade 275. The assembled container shall be filled to rated capacity with water at ambient temperature, closed, and prepared as for shipment. Each of the samples shall then be subject to constant load of 250 pounds and soaked with water for one hour by directing a steady stream of water (1 gallon per minute minimum) against the sidewall of the box. The prescribed load for 24 hours and then be examined for top and bottom compression. The box must be supporting the load after the period, and there shall be no more than 1/2 –inch vertical deflection.
Leakage test (room temperature). The plastic container selected for testing shall be filled with water which has been strongly colored with ink or other suitable coloring agent which is not a permeator of polyethylene; 1/10 of 1.0 percent Aerosol OT shall also be added to the water as a wetting agent. Caps shall be screwed down and tightened or spouts sealed, as applicable. The plastic container shall then be placed with spout down upon a sheet of white blottering paper. Examine after 15 minutes. Discoloration of the paper by the colored water is regarded as failure of the test.
Workmanship. The containers shall conform to the salient characteristics of the commercial item description. Containers shall be free from any workmanship or design defects that affect appearance or serviceability.
Regulatory requirements. The offeror/contractor is encouraged to use recovered materials in accordance with Public Law 94-580 to the maximum extent practical.
