The edge crush test (ECT) tests how much weight can be stacked on top of a box without the edges being damaged. Common ECT ratings are 32 for single-wall boxes, 44-48 for double-wall boxes and 60-90 for triple wall boxes. Modern production and shipping have changed drastically, and the testing methods we use to measure a package's strength ...

Flat crush testing is a measure of the load bearing capability of corrugated board to loads acting perpendicular to the fluting. Results are quoted in kPa. We test to British Standard BS EN 23035 and International Standard ISO 3035. Ring Crush Testing Ring crush testing is used to measure the edgewise compression of paper and board materials.

The Edge Crush Test is a traditional corrugated box test of compression strength. We normally measure ECT using the clamp method to hold the sample. according to TAPPI Test Method T839. Many corrugated boxes are specified in terms of ECT, expressed as lbs/inch. The test is performed on combined board with the flutes in the vertical, or cross ...

Edge crush testing, also known as ECT, is a cost effective and convenient way to work out the peak load that a material can handle. It is one of the most popular ways of measuring the strength of cardboard, paperboard and corrugated paper. If you're using cardboard in your packaging or products, ECT is invaluable in helping maintain and ...

ECT (edge crush test) and BCT (box crush test) are two completely separate tests. However, they are similar to each other in some aspects. In the edge crush test, 2 x 2 cardboard samples are taken and the edge between the compression plates is crushed with a desktop machine. In the box crush test, the entire box is crushed between the ...

Specifications. Paper Edge Crush Tester. 1puter Servo. 2.Multi-function. 3.Paper and Packaging Ring. 4.OEM. 1.Usage. Paper Edge Crush Tester,Computer servo multi-function carton tension and compression strength tester can do a full range of testing, which includes Ring Crush Testing, Flat Crush testing, Edge Compressive Testing, Adhensive ...

The fundamental difference between these two tests is that the Burst Strength Test requires a minimum basis weight of the paperboard. That is, the Burst Test requires that the base papers used to make corrugated fiberboard weigh at least a certain minimum number of pounds per given unit area. However, the Edge Crush Test eliminated this ...

Edge Crush Test Calculator is a highly accurate and reliable testing method used by the packaging industry to measure the strength of corrugated cardboard and other materials. The use of ECT in ...

As a representative example an unsymmetrical 5-ply sample (with E and B flute) was used in this study. In order to exclude unreliable displacement measurement in the standard edge crush test, virtual strain gauges were used. Video extensometry was employed to collect measurements from the outer surfaces of the sample on both sides.

The accuracy of test results is heavily influenced by testing conditions. The Presto Edge Crush Tester is specifically designed to minimize the impact of fluctuations on the edge-wise compressive strength of the material. This feature ensures that users consistently obtain accurate Edge Crush Test (ECT) results. 2.

CT-21 Crush Tester: The Regmed CT-21 Crush Tester can perform corrugated board tests involving edge crush, ring crush, flat crush and pin adhesion. Compression Testers Box Compression Tester (RL-BCT-A): The Rycolab Box Compression Tester measures the compression strength of boxes and cartons to evaluate their abilities to withstand specific …

Crush resistance is tested through specific methodologies using equipment like a crush tester or Universal Testing Machine. The testing can include various types such as …

ECT is a measure of the edgewise compressive strength of corrugated board. It is measured by compressing a small segment of board on edge between two rigid platens or plates perpendicular to the direction of the flutes until a peak load is established. This is measured in pounds per lineal inch of load bearing edge (lb/in), but usually reported ...

How to Use the Edge Crush Test. The resistance of edge crush, R, is measured and specified in kilonewtons per meter (KN/m) and it can be calculated as following; R = 0.01 x Fmax, where Fmax shows the average value of maximum force and is calculated in newton. There are many material testing methods used to measure the …

Edge crush test results (on the FEMat ECT/FCT laboratory apparatus). Materials 2021, 14, x FOR PEER REVIEW 9 of 16 Figure 10b, the applied force is shown in terms of the image number.

The standard edge crush test (ECT) allows the determination of the crushing strength of the corrugated cardboard. Unfortunately, this test cannot be used to estimate …

The tester then continues further until the corrugated board collapses and the software automatically calculates the Edge Crush Resistance value in the desired unit of measurement (lb/in, N/mm). Bench-top models of ECT Compression Testers are available in capacities of 2.5 kN – 10 kN depending on the range of board to be test

ECT = edge crush test value. T=Thickness of CFB board (wall thickness) Z= Perimeter of the box i.e. (2 L + 2 W) Testing the edge-wise compression strength of corrugated boxes or cardboards is important in determining whether the materials will be strong enough to withstand the rigors of shipping or not.

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 …

The edge crush test (ECT) is a standard te st to assess the compressive strength of. corrugated board. The test is performed a ccording to FEFCO DIN EN ISO 3037 [25,26], where a 100 mm long and 25 ...

Abstract: The standard edge crush test (ECT) allows the determination of the crushing strength of the corrugated cardboard. Unfortunately, this test cannot be used to estimate the compressive stiffness, which is an equally important parameter. This is because any attempt to determine this parameter using current lab equipment quickly …

That's because ECT stands for "Edge Crush Test," a measure that – depending on its results – could mean the difference between very happy customers or lot of requests for refunds, damaged items, and possible lost business. ... There are good reasons an edge crush test is performed. First, it allows for quality control, which is ...

Simple test methods such as the Edge Crush Test (ECT) enable businesses to understand the maximum weight a box can withstand and the overall stacking strength.

The Mullen Burst Test uses a pressurized diaphragm to measure how much pressure (in pounds per square inch) the side of a corrugated box can take before it breaks. And analogy to this would be: how hard do you have to punch the side of a box to break through it. The harder you had to punch, the stronger the box was, full stop.
