Short-Span Compressive Strength of a Specimen Gripped in an S-Shape (S-Test)

Determination of short-span compressive strength to DIN 5014 on corrugated medium. The S-test measures the compressive strength of a specimen gripped in an S-shape. This method was developed for performing tests on corrugated mediums. The compressive strength of a specimen gripped in an S-shape is measured in the same manner as the SCT and measures the maximum compressive force that the specimen can withstand parallel to the paper plane. Thus, the test leads to double flexure loading of the test strip which takes the form of the letter “S”
