Flat crush of corrugated medium (CMT test)
The flat crush test, also known as the Concora Medium Test (CMT), measures the maximum force a corrugated medium can withstand before flute collapse. In CMT testing, the medium is first formed into flutes using a laboratory fluter before testing.

What is fastening torque
Fastening torque refers to the rotational force applied to tighten a fastener, typically measured in Newton-metres (N·m) or pound-force inches (lbf·in). The correct torque value ensures adequate clamping without overstressing components.
