ECT is a measure of the edgewise compressive strength of corrugated board. It is measured by compressing a predefined section of board on its edge between two rigid platens. This compression is performed perpendicularly to the direction of the flutes until the board collapses and a peak load is reached. This load is reported as force per unit

This was despite the fact that these ‘recycled board’ cases still had very good compression and damage resistance qualities, as evidenced in the Edge Crush Test (ECT). The Mullen Burst Test measures the force required to puncture the face of corrugated board and is reported in pounds per square inch (psi) .. boards are thus rated accordingly e.g. #275.

ECT ist ein Maß für die hochkantige Druckfestigkeit von Wellpappe. Es wird gemessen, indem ein vordefinierter Brettabschnitt an seiner Kante zwischen zwei starren Platten zusammengedrückt wird.

The fundamental difference between these two tests is that the Burst Strength Test requires a minimum basis weight of the paperboard. That is, the Burst Test requires that the base papers used to make corrugated fiberboard weigh at least a certain minimum number of pounds per given unit area.

Bursting strength is reported in pounds (for example, 275#). A newer standard that has achieved widespread acceptance is the Edge Crush Test (ECT). This is a true performance test and is directly related to the stacking strength of a carton. ECT is a measure of the edgewise compressive strength of corrugated board.
