How Does an Edge Crush Tester Work?
The Edge Crush Test units are pretty straightforward. It clamps a sample between two plates and presses on its edge until it buckles. By measuring the force needed to crush the sample, it tells us how strong it is, usually in pounds per inch (LPI) or kilo new tons per meter (kN/m).
Understanding Edge Crush Test Parameters
This test assesses several crucial factors: the material’s resistance to being flattened, its capacity to withstand vertical pressure, and its overall durability. These parameters help determine the resilience of corrugated boxes under various stresses and conditions. To aid in understanding these factors, manufacturers often refer to an edge crush test chart, which provides insights into the material’s performance under different testing conditions.
Therefore, to simplify this testing process for manufacturers, Laboratory testing instruments have developed the ECT edge crush test for assessing the edge-wise compressive strength of materials.
Edge crush test formula
To gauge the strength of corrugated boxes under pressure during shipping, McKee’s formula helps calculate compression strength.
It factors in the ECT (Edge Crush Test Calculator) value, box thickness (T), and a constant (k) to derive the result.
This test ensures materials inside, like those tested with Hot Air Oven and Bursting Strength Tester, can withstand shipping pressures. Laboratory Testing Instruments offers ECT edge crush test equipment for easy testing, simplifying the process for manufacturers.
