TEST OBJECTIVE: To conduct Vibration, Incline Impact, Racking and Compression Tests on the submitted NextPallet samples, in accordance with instructions from Pratt Industries. ITEMS TESTED: The test samples were identified by the Pratt Industries. as follows: 3 pc. – 40 3/8” x 48” x 4 5/8” high, wooden pallet with all glued joints, encased in single wall, C flute corrugated fiberboard shell. Average pallet weight 26.5 lbs. VIBRATION TEST PROCEDURE: The pallet under test was loaded with 2400 lbs. of weight, consisting of water filled plastic pails, stacked on the pallet 5-layers high. The load was secured to the pallet with plastic stretch wrap film. The assembled pallet load was placed on the table of the hydraulic vibration machine, in its normal shipping orientation. Restraining fences were placed around the pallet to prevent it from moving off the vibration table (see Photo No. 1). The pallet was subjected to 120 minutes of random vibration in accordance with power spectral density profile in ASTM D4169-16, Truck Vibration, Assurance Level I, with an overall level of 0.7 grms. VIBRATION TEST RESULTS: No visible damage was noted to the pallet as a result of the vibration test (see Photos No. 2 and 3). INCLINE IMPACT TEST PROCEDURE: The pallet under test was loaded with 2400 lbs. of weight, consisting of 70-lbs. sandbags, stacked on the pallet 6-layers high. The load was secured to the pallet with plastic stretch wrap film. The assembled pallet load placed on a dolly of the incline impact test machine (see Photo No. 4). The travel of the dolly was adjusted to produce the impact velocity of 5.75 ft./sec. One impact was performed on each of the four sides of the pallet load. INCLINE IMPACT TEST RESULTS: There was damage noted to the pallet load as a result of the side impact test. There was considerable shifting of the load on the pallet on the side opposite to the impact (see Photos No. 5).

RACKING DEFLECTION TEST PROCEDURE: The pallet under test was centered with its long span upon two steel I-beams, with their inner edges separated by a distance of 44 inches. A dial indicator was placed underneath the pallet at its geometrical center. The dial indicator was set at 0” with the pallet empty. The pallet was evenly loaded using bags filled with lead shot evenly distributed on the top deck of the pallet in 4 layers, followed by the remainder load consisting of lead weights. The total top load was 2400 lbs. The load was maintained on the pallet for 72 hours. See Photos No. 6 and 7 for overview of the test setup. RACKING DEFLECTION TEST RESULTS: The deflection immediately after loading was 0.554”. The deflection after 72 hours was 0.868”. There was no permanent damage noted to the pallet as a result of the racking test. COMPRESSION TEST PROCEDURE: Flat Compression: The empty pallet under test was centered on the bottom, floating platen of a compression test machine, equipped with the load measuring device. No special supports were placed under the bottom or on the top of the pallet (see Photo No. 8). The compressive load was applied to the top of the top pallet at a rate of 1/2" per minute. The test was continued until failure or a top load of 20,000 lbs, whichever occurred first. Compression With Top Loading Bars: After flat compression test, the pallet was centered on the bottom, floating platen of a compression test machine, equipped with the load measuring device. No special supports were placed under the bottom pallet. Two 1 ½” wide rectangular steel bars were placed on the top of the pallet, parallel to the short dimension, centered at the midspan of the fork tyne openings (see Photo No. 9). The compressive load was applied to the top of the top pallet through the loading bars at a rate of 1/2" per minute. The test was continued until failure or a top load of 20,000 lbs, whichever occurred first. COMPRESSION TEST RESULTS: Flat Compression: The pallet withstood a top load of 20,000 lbs. without any visible damage. Compression With Top Loading Bars: The top deck boards cracked at 10,900 lbs. load (see Photo No. 10) Upon completion of testing, the test materials were returned to Pratt Industries for final evaluation.
