EDGE CRUSH TEST
The Edge Crush Test is simply a method used to determine the "stacking" or "crushing" of a piece of corrugated board. The test is conducted to determine the force that will crush a containerboard standing on an edge. The ECT will determine the probable compression strength of the container made from the board.
