Flat Crush of Corrugated Medium (CMT Test)
This method describes a procedure for measuring the crushing resistance of a laboratory fluted strip of 26 pound corrugating medium, and provides a means of estimating, in the laboratory, the potential flat crush resistance of a corrugated board. Other grades may not correlate with their potential.
