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

DIN 5014 (draft)

Purpose of the DIN 5014 test

Determination of the short-span compressive strength on corrugating medium to DIN 5014

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”

Short-Span Compression Test of a Specimen Gripped in an S-Shape (S-Test) with ZwickRoell

  • The specimen is secured between two clamps, with a 1 mm offset from the sheet plane. A compressive load is then applied parallel to the paper plane. This results in a double flexure load at a test length of 4 mm. At maximum load, failure of the structure occurs in the form of buckling
  • Pairs of jaws featuring precision vertical and horizontal guidance
  • Gripping force is applied pneumatically
