Brief explanation of the test:
- One side of the formed corrugated 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 the A and B flutes are tested. The behavior of other types of fluting must therefore be determined mathematically in order to obtain their crush resistance.

- Specimen production is time-consuming and requires a great deal of skill. With the fluter, specimen preparation is quick and efficient.
- The compression plates are suitable for the ring crush test (RCT), the flat crush test (FCT), the edge crush test (ECT) and the corrugating medium test (CMT).
- Precision-guided compression platens ensure extremely high lateral stiffness, guaranteeing reproducible determination of characteristic values.
