Corrugated Boxes – Edge Crush Test (ECT) | TheBoxery

The 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. The edge crush resistance is included in the McKee formula and is therefore of particular importance for quality control in corrugated ...

Ring Crush Test Determining the Ring Crush Strength ...

The ring crush test is similar to the short-span compression test in that the strength of the liner or fluting is measured both in the machine direction and perpendicular to it. It is important that force application to the specimen is exactly perpendicular during these tests. The results of this test are highly dependent on proper specimen preparation.
