Corrugated Boxes â Edge Crush Test (ECT) There are currently two tests used throughout the corrugated industry to determine strength. Historically, the long time industry standard has been the Bursting (Mullen) Test, which is related to the rough handling durability of corrugated material.
Somewhere along the line, ECT (Edge Crush Test) was developed as another method of grading corrugated board. The Mullen Burst test pressures a rubber diaphragm bubble against the board in a defined area to measure the pounds of pressure per square inch to burst the board. The ECT test takes a defined sample board size and measure the straight compression force for that sample size.
