2 - Edge Crush Test (ECT) The Edge Crush Test, or ECT, measures how much force the corners and edges of a corrugated material can take until it's crushed. . A corrugated box with an ECT rating of 32 means that it can withstand a stack of up to 65 pounds. FedEx and UPS follow ISTA standards for packaging 30 pounds or less to be at least 32 ECT .
The simplified McKee formula above provides a quick estimate that should not be used to rate the strength of an actual box. Such an estimate shall not to be used in place of testing conditioned test samples in a controlled, repeatable test environment, with calibrated instrumentation, validated machines, and trained test operators. The Edge Crush Test (ECT) measures the strength of the box when it’s stacked, particularly how much weight it can withstand before the material crumples or b.
Box Crush Test and the Chalmers DST Ian Chalmers January 2015 Summary BCT can be predicted from paper properties and box dimensions but only for undamaged boxes. Crushing corrugated board lowers the boards MD Torsional Stiffness (MDTS) which is the most sensitive structural property of corrugated board. Failure of
What is the difference between box compression test and edge crush test? The box compression test measures the compressive strength of a complete box, evaluating how much load the box can withstand without failure. The edge crush test, on the other hand, specifically measures the edgewise compressive strength of corrugated board.Customised engineering example Boxes for the consumer and transit packaging industries must be as light as possible whilst still retaining a robustness to contain and protect their contents and also have the strength to stand up to shipping, handling and stacking requirements in service. The use of corrugation adds rigidity to paper and card packaging materials, which are tested in . The Mullen Test is generally considered to be more accurate for boxes that are subject to individual rough handling, including being stacked and re-stacked and taken on and off of hand trucks individually. However, because most goods are now shipped on pallets, the industry developed another test: The Edge Crush Test. The Edge Crush Test
We carry equipment to test crush strength. This includes our CT-21 crush tester & RL-CT-A crush tester. . The RL-BCT-A crush tester is designed for testing the compressive strength of corrugated boxes/cartons according to international standards to evaluate the ability to withstand specific loads. This box compression tester conforms to ISTA 6. With corrugated boxes typically constructed of single, double or triple wall boards, knowing the ECT and Mullen Score of a box can come in handy for the higher the rating, the more weight it can stand or contain. The ECT and Mullen crush test ratings for a single wall board box are as follows:

The burst test represents how much pressure can be applied before the wall of a box will rupture. The edge crush test is an indicator of the top-to-bottom pressure needed before a box will be crushed. This is important if you will need to stack a number of boxes, especially in a warehouse environment, and is the most popular box standard.Box Crush Test is to determine the max strength to failure of corrugated cardboard boxes and folding boxes. Labthink Box Compression Tester can perform box crush test in accordance with DIN ISO 12048 and TAPPI T804.
