Stack Test

One of the primary functions of the container system is to provide the ability to stack the containers during transit or warehousing in a safe manner. The test procedures for Hazmat package testing specifically utilize a common type of dead load stacking in order to more closely simulate the exact distribution or warehouse stacking environment. 

The stack test procedure requires that a dead load be placed on top of the package system that represents approximately 200% of the anticipated load during distribution. It must be a “free load” in order to lean if the stack should start to lean in any one direction. It is also necessary for the stack to maintain this level of top load for a minimum period of 24 hours. Westpak uses only certified loads calibrated yearly for this process.
