WebNov 4, 2013 · The flat crush test is a measure of the flute rigidity of the corrugated board. A high flat crush value indicates a good combination of flute formation and at least adequate medium strength. A low flat crush indicates a number of faulty conditions. Among these are low strength medium, leaning flutes, and/or crushed flutes. bbq paul idahoWebJul 9, 2024 · ECT is a measure of the edgewise compressive strength of corrugated board. It is measured by compressing a predefined section of board on its edge between two rigid platens. This compression is performed perpendicularly to the direction of the flutes until the board collapses and a peak load is reached. This load is reported as force per unit ... bbq pegram tn

"WebIt is also possible to determine the compression strength of the box (CFB) by using ECT tester with McKee’s formula i.e.Compression strength = k. ECT x T x Z Where K= Constant ECT = edge crush test value T=Thickness of CFB board (wall thickness) Z= Perimeter of the box i.e. (2 L + 2 W) " - Flat crush test formula

Flat crush test formula

WebThe ECT can easily determine the compressive strength of the box using the McKee’s formula, where compression strength is equal to k. ECT x T x Z, here k is constant, ECT is edge crush test value, T is the thickness of CFB board (wall thickness), and Z is Perimeter of the box i.e. (2 L + 2 W).
