Ο short span compression tester is an essential instrument in the paper and packaging industries, specifically designed to evaluate the compressive strength of paper and board materials. By simulating real-world compression forces, this tester helps manufacturers assess the ability of paper products to withstand pressure during handling, stacking, and transportation.
Cell Instruments’ SCT-01 Short Span Compression Tester offers high performance, ease of operation, and compliance with international standards, especially ISO 9895, which governs the SCT test method.
SCT Test and ISO 9895
Ο SCT test (Short-Span Compression Test) as defined in ISO 9895, measures the compressive strength of paper and board over a very short span—typically 0.70 mm. This test is vital for materials used in the production of corrugated boxes, cartons, and paperboard containers, where high compressive performance is required.
Unlike traditional compression tests, the SCT test focuses on edgewise compressive strength, simulating conditions during stacking and palletization. It is particularly suitable for papers and boards ranging in grammage from 100 g/m² to 400 g/m².
Key Features of SCT-01 Short Span Compression Tester
Ο SCT-01 Short Span Compression Tester from Cell Instruments is engineered for accuracy and durability. Its advanced features meet the rigorous needs of laboratory and industrial environments:
Σύστημα ελεγχόμενο από PLC with HMI touch-screen operation for user-friendly interaction
Πνευματική σύσφιξη δείγματος with adjustable clamping force to ensure test consistency
Constant test speed with programmable settings for various material types
Emergency stop button και over-range protection for enhanced safety
Multi-unit force display: N (Newtons), kgf (Kilogram-force), and lbf (Pound-force)
Built-in dot matrix printer for instant results printing
RS 232 COM port and optional PC software for data management and traceability
How the SCT Test Works
1. Sample Preparation
Cutting the Test Piece
Prepare rectangular test specimens from the paper or board sample. Each specimen should measure 15 mm in width και 75 mm in length.Conditioning the Samples
Condition the specimens in a controlled environment of 23 ± 1°C temperature και 50 ± 2% relative humidity for at least 4 hours before testing, as required by ISO 187 (referenced by ISO 9895). This stabilizes the paper’s physical properties.Selecting the Test Direction
Determine whether the test will be conducted in the machine direction (MD) ή cross direction (CD). Prepare a minimum of five specimens for each direction to ensure statistical validity.
2. Mounting the Sample
Open Clamps
Using the pneumatic control system, open the clamps.Insert the Test Piece
Center the specimen between the 30 mm-long clamps, ensuring it is aligned with the jaws and is positioned evenly along the width.Apply Clamping Pressure
Activate the pneumatic clamping mechanism to grip the specimen. The high-friction surfaces help prevent slippage during compression.
3. Executing the Test
Ξεκινήστε το Test
Press the start button on the HMI panel to begin the compression.Compression Process
The movable clamps move toward each other at the set speed of 3 mm/min. As the span closes, the paper or board is subjected to increasing edgewise compressive force.Failure Detection
The test continues until the specimen fails structurally—typically by buckling or sudden breakage. The instrument automatically records the maximum force applied before failure.
4. Test Completion and Result Recording
Display of Results
The compressive strength is displayed in selectable units:N (Newtons)
kgf (Kilogram-force)
lbf (Pound-force)
Print or Export Data
Results can be printed directly via the embedded dot matrix printer or exported through the RS-232 COM port using optional PC software.
Repeat the procedure for all prepared specimens in both machine and cross directions to generate a comprehensive profile.
