Standard Test Methods for Rough Handling of Unitized Loads and Large Shipping Cases and Crates

SCOPE
1.1 These test methods cover testing the integrity of unitized loads and large shipping cases and crates as well as the ability of the contents to endure rough handling. Not all of the test methods are applicable to all products, containers, and loads. These test methods are applicable to common means of material handling.
