Corrugating Medium Test (CMT)

DIN EN ISO 7263-1/-2, TAPPI T 809

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.
