Overview
The Short Span Compression Tester (SCT) Is A Precision Laboratory Instrument Designed To Determine The Compressive Strength Of Paper And Paperboard Under Short-Span Loading Conditions.
This Test Method Is Widely Used For Evaluating:
Fluting Medium
Test Liner
Kraft Liner
Folding Boxboard
Containerboard (100–400 Gsm Approx.)
The Sct Value Plays A Critical Role In Predicting The Stacking Strength And Load-Bearing Performance Of Corrugated Boxes. By Optimizing Compression Strength Of Liners And Fluting Media, Manufacturers Can Reduce Fiber Usage While Maintaining Required Box Strength.
Test Principle
The Short Span Compression Test Measures The Maximum Compressive Force Sustained By A Specimen Clamped Over A Very Short Span Before Failure Occurs.
Working Process:
A Prepared Strip Sample Is Secured Between Precision Pneumatic Clamps.
A Vertical Compressive Force Is Applied At A Controlled Rate.
The Instrument Records The Peak Force At Rupture.
The Compression Strength Is Calculated And Displayed Digitally.
The Short-Span Configuration Eliminates Buckling Effects, Ensuring That The Test Measures Intrinsic Fiber Strength Rather Than Structural Instability.
Standards Compliance
