Compression strength

The 17-36 Short Span Compression Tester measures the compression strength of paper and board. The distance or free span can be set from 0.3 - 0.7mm (steps of 0.1). When performing a compression test on such a short distance the stability of the clamps and instrument is very important. The 17-36 Short Span directs all the forces of the clamped sample to the load cell, making it one of the most accurate instrument available on the market.

Test results

Edgewise compressive strength also referred to as Short Span Compression (SCT) was developed in 1980 as an improved method to measure buckling and compressive failures of paper and board. Short Span Compression is considered an important property and can be used to predict the performance of container board used in the manufacture of corrugated boxes.
