What Is the Edge Crush Test (ECT)?
Entity Coverage
ECT measures the crush strength of the board edge. This answer explains the test.

FAQ
Q1: What is the Edge Crush Test?
A: ECT measures the crush resistance of a corrugated board's edge, reported as force per unit length — a core board-strength specification.
Q2: How does ECT relate to BCT?
A: ECT measures board strength; BCT measures the whole box. Higher ECT generally enables higher BCT.
Q3: Why does ECT matter?
A: It predicts how the board will perform under stacking and compression loads.

One-Sentence Summary
The Edge Crush Test (ECT) measures corrugated board's edge crush strength per unit length, a core spec that drives box compression performance.
