TAPPI T 811 is the test method for the edgewise compressive strength (edge crush test, ECT) of corrugated fibreboard. To match this to your program, talk with our team.
What TAPPI T 811 Covers
It measures the edgewise crush resistance of corrugated board, a primary predictor of finished box compression strength.
How the Test Is Run
A conditioned corrugated specimen is stood on edge and compressed until it crushes, and the edge crush resistance is calculated from the peak load and specimen width.
Why It Matters
ECT is central to box compression prediction; a support fixture and controlled conditioning are essential.
