The Edge Crush Test (ECT) is a performance test that is directly related to the stacking strength of a box. ECT is a measure of the edge compression strength of a corrugated box side wall. It is measured by compressing a small segment of the box side wall on edge between two rigid plates perpendicular to the direction of the flutes until a peak load is established. This is measured in pounds per lineal inch of load (lb/in), but usually reported as an ECT value (for example, 32 ECT).
