The Edge Crush Test (ECT), conducted according to TAPPI T 838 and similar, is a means to determine the ability of corrugated paperboard to withstand a top load when it is fabricated into a corrugated shipping container. The test involves carefully cutting a sample of material and subjecting it to a top load in the edge down configuration. The test gives an indication of the ability of the box constructed with that material to withstand static and dynamic top loading as would occur during warehousing or distribution.
The same procedure can be utilized to test and evaluate the crush resistance of a variety of different materials and structures.
