TAPPI T 826 is the test method for the short-span compressive strength (SCT) of paperboard. To match this to your program, talk with our team.
What TAPPI T 826 Covers
It measures the in-plane compressive strength of paperboard over a very short span, an indicator of stacking and box strength.
How the Test Is Run
A conditioned strip is clamped over a short unsupported span and compressed until it fails, and the short-span compressive strength is calculated from the peak load and width.
Why It Matters
SCT correlates with box compression; a precise short-span fixture and controlled conditioning are essential.
