Tappi ect method
WebThe edge crush test (ECT) to DIN EN ISO 3037 or TAPPI T 811 provides information on the strength of corrugated cardboard with flutes positioned vertically. It is important that force application to the specimen is exactly perpendicular during these tests.

WebJul 20, 2024 · 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.
