End pads may be cracked with no separation. Cartons should have no tearing or de-bonding of the seam edge.5.7.2Compression Test: Vehicle Stacking Assurance Level IISchedule B – Warehouse Stacking and Vehicle StackingThis test is intended to determine the ability of the shipping unit to withstand thecompressive loads that occur during warehouse storage or vehicle transport. Theformula calculates the compressive load over the largest footprint of the package usinga shipping density factor. A safety factor is used to take into effect time in storage,stacking pattern, variables in container strength and atmospheric conditions(temperature, humidity). The test is to be conducted by loading the shipping unit to thecomputed load value, as calculated below. The compressive load is to be uniformlydistributed about its largest footprint. Remove the load within 3 seconds after reachingthe specified value.Formula:L = Mf*J*((l*w*h)/K)*((H-h)/h)*FL = Minimum Required Test Load=lb or NMf = Shipping Cargo Density factor = 10.0 lb/ft3 or 160 kg/m3J = conversion factor = 1 lbf/lb or 9.8 N/kgl = length of shipping unit = in or mw = width of shipping unit = in or mh = height of shipping unit = in or mK = conversion factor = 1728 in3/ft3 or 1 m3/m3H = maximum stack height = 108.0 in or 2.7mF = factor to account for individual factors described above = 7Acceptance Criteria:1.

Compression test cannot cause the outer shipping container to crease, split or tear at the joint.Test Conditioning: 73.4o F (+/-2o F) [23o C (+/-1o C)] and 50% (+/-2%) relative humidity in accordance with practice D 4332.Ref: ASTM D 41695.7.3 Loose Load Vibration Method A1—Repetitive Shock TestPlace the test specimen on the test machine platform in its normal shipping orientation. Attach restraining devices to the platform to prevent the specimen from moving horizontally off the platform and to prevent excessive rocking without restricting the vertical movement. Adjust the restraining devices to permit free movement of the specimen of approximately 10 mm (0.4 in.) in any horizontal direction from its center position. Start the vibration of the platform at a frequency of about 2 Hz and steadily increase the frequency until some portion of the test specimen repeatedly leaves the test surface. To ensure that the test specimen receives acontinuing series of repetitive shocks, a shim with a 1.6 mm (1 /16 -in.) thickness and a width of 50 mm (2.0 in.) shall be used to determine when the test specimen is leaving the testplatform. The shim should be inserted under the package a minimum of 100 mm (4.0 in.) and moved intermittently along one entire length of the package.Continue the test at this frequency for a period of 1 hour. The test may be stoppedmomentarily to inspect for damage.If the container might possibly be transported in any other orientations, test at least onecontainer in each possible orientation for the full-specified test duration.Inspect the container and its contents and record any damage or deterioration resulting from the test.Ref: ASTM D 4169 – 99, ASTM D 999 – 965.7.4 Schedule E-Vehicle VibrationPerform the test for each possible shipping orientation.
