zwickiLine for Flexible Low-Force Testing.
In the short-span compression test the compressive strength of paper is determined according to ISO 9895, DIN 54518 or TAPPI T 826.
One side of the formed medium is adhered to a backing strip and subjected to compressive loading. The maximum load characterizes the behavior of multi-wall corrugated board during subsequent processing operations (punching, printing). It is important that force application to the specimen is exactly perpendicular during these tests.
Disadvantages of this method: Only A-flute and B-flute are tested. The behavior of other types of fluting must therefore be determined mathematically in order to obtain their crush resistance.
