ISO 12192 Ring Crush (RCT) Compressive Strength Test for Paper and Board

← Back to all standards

ISO 12192 is the test method for the edgewise compressive strength of paper and paperboard. To match this to your program, talk with our team.

What ISO 12192 Covers

It measures how much edgewise compression paper or board can carry before it buckles, an in-plane strength related to stacking performance.

How the Test Is Run

A conditioned specimen is supported and compressed on its edge until it fails by buckling, and the edgewise compressive strength is calculated from the peak load and width.

Why It Matters

Edgewise strength contributes to stacking and box performance; a support fixture that prevents premature buckling is essential.
