In 2018 the S-Test is developed to replace the CMT Test. The S-Test measures the compression strength of a flute. The sample is clamped on both sides with a gab of 4mm. The clamps have an offset of 1mm. The 1mm offset automatically pushes the sample in a shape that corresponds to the flute of corrugated board. In this way the shape of the flute is simulated. The sample is compressed simulating the pressure on a corrugated box. The test is finished in a few seconds and gives you the peak value. The S-Test can be correlated to the first plateau of the CMT.
