This manual describes a procedure for the measuring of the crushing resistance of a fluted strip of corrugating medium in the laboratory.

The measurement for the rigidity of the fluted structure is one of the desirable characteristics of corrugated board. The procedure of corrugating medium test (CMT)
provides a means of estimating the potential flat crush resistance of a corrugated board in the laboratory. This test permits the evaluation of corrugating medium before it is fabricated into combined board. The results may also provide a basis for the judgement of fabrication efficiency.

The main function of this equipment is to heat and shape the sample of the corrugating medium into the sample to be tested by the Ring Crush Tester that yields the CMT value.
