You could always call the Package Testing Dept.(800 633 7019 option 5). I can tell you the tests that my box was subjected to (it list them on the report you receive after it is tested).
My tests included a drop, a compression/deflection test, and vibration. My box was loaded to ~420 lbs, deflected .21 inches, was dropped from 30 inches, and was vibrated for 45 minutes randomly.
