The ECT test is widely acceptable test that has set a new standard and is directly related to the stacking strength of a corrugated box or carton. The edgewise compressive strength in the corrugated box is measured by compressing a small specimen of material. The Edge Crush Tester is used to determine the compressive strength of the sides of the packaging boxes such as corrugated boxes, solid boxes of fiber, etc. The instrument performs the edge crush test, ring crush test, flat crush test as per the standards. The equipment is user-friendly and available as computerized cum digital model. The crushing strength is measured as KN per unit, and the value of the crush test is significant depending on the paste bonding.
During the testing procedure, if edge crushing force value is higher means the box has a high stiffness level. The Edge Crush Tester allows easy comparison of the quality and strength of corrugated boxes. The 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).
The testing equipment is capable of creating the testing environment and is recommended for paper making, quality inspection, packaging and many more. The equipment efficiently determines the possible compression strength of the solid fiberboard or corrugated boxes through the testing of the packaging material such as paper or paperboard.
