Descriere

CCT – Corrugated Crush Test: A sample is corrugated between heated corrugating rolls. The sample is fixed in a special jig that is adapted to the corrugated shape. The crushing force is applied and measured parallel to the top of the corrugating medium. The CCT value is the maximal force that the sample can withstand before it breaks.

Applicable standards：SCAN P 42, TAPPI T 843

CMT – Concora Medium Test: A sample is corrugated between heated corrugating rolls. The flute is fixed and held together by a pressure-sensitive tape, so that single-sided corrugated board is imitated. The crushing force is applied vertically to the paper ,then the breaking force is measured. The CMT value is the maximal force the sample can withstand before it breaks.
