Edge crush test - Wikipedia

The edge crush test is a laboratory test method that is used to measure the cross-direction crushing of a sample of corrugated board.It gives information on the ability of a particular board construction to resist crushing. It provides some relationship with the peak top-to-bottom compression strength of empty singlewall regular slotted containers in laboratory conditions.
