The edge crush test is a laboratory test method that is used to measure the cross-direction crushing of a sample of corrugated board. It gives information on the ability of a particular board construction to resist crushing. It provides some relationship with the peak top-to-bottom . The Edge Crush Test (ECT) is a good measure of stacking strength and is an important indicator of the performance of corrugated board boxes in general. ECT value predicts the maximum load a box can bear .When predicting top-to-bottom compression from corrugated board ECT, the impact of the converting process must be considered (see Manufacturing Considerations). ECT testing is .

A newer standard that has achieved widespread acceptance is the Edge Crush Test (ECT). This is a true performance test and is directly related to the stacking strength of a carton. 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 .Compression and Crush Testing. Contact Angle Testing. Corrosion Testing. Corrugated Testing. . The same box would have a 32 ECT rating. Edge crush testing conversion chart. Box : Mullen Burst Test: Edge Crush Test: Max. Load per Box: Standard: 200# 32 ECT: 40lbs: Heavy Duty: 275# 44 ECT: 65lbs: Heavy Duty + Double Wall: 275# 48 ECT:Rationale of TAPPI T811 Edge Compression Test (ECT) Corrugated: TAPPI T811 – Edgewise Compressive Strength of Corrugated Fiberboard (ECT). Data collected can be used along with flexural stiffness and box dimensions to accurately predict the overall top-to-bottom compression strength of corrugated boxes.
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 ECT Value is often provided on the BMC (Box Manufacturer’s Certificate).作为测试纸张、纸板和瓦楞纸板等材料峰值负荷的最常见方法之一，ETC (Edge crush testing)边压测试是任何良好瓦楞质量保证过程中的关键因素。 . 有各种高度精确的机器可以帮助您获得一致的ECT结果。如17-40 Series Box Compression Tester(17-40系列箱式压缩试验机)，它 .The Edge Compression Test method or ECT describes procedures for determining the edgewise compressive strength, parallel to the flutes, of a short column of single-, double-, or triple-wall corrugated fiberboard (constant strain rate, or constant load rate). The test method includes procedures for cutting the test specimen (saw cutting and knife cutting), one .

ECT (Edge Crush Test) and BCT (Box Compression Test) of a corrugated box. During the design and production of corrugated boxes, assessing their strength and compression resistance is crucial to ensure their performance in the transportation and storage of products.ECT – Edge Crush Test 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
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 .This was despite the fact that these ‘recycled board’ cases still had very good compression and damage resistance qualities, as evidenced in the Edge Crush Test (ECT). The Mullen Burst Test measures the force required to puncture the face of corrugated board and is reported in pounds per square inch (psi) .. boards are thus rated .
Combining compression and bending strengths of the facings provides a useful predictive model for ECT similar to BCT with improved accuracy. A combined series of laboratory-made and commercial corrugated boards were investigated for ECT using this combined compression strength and bending resistance model. Edge Compression Strength Test MethodsThe Edge Crush Test (ECT) is a standardized method conducted in laboratories to evaluate the crushing strength of corrugated cardboard’s cross-section. This test provides essential insights into the corrugated cardboard’s capacity to . Applied Paper Technology provides independent technical services, testing, and interpretation of results. Our test procedures comply with TAPPI Test Methods,.
How is an edge crush test calculated? An ECT rating is calculated by determining the force in pounds per lineal inch of load bearing edge (lb./in) that a sample can take before failure. Get a clearer picture of how ECT compares to other testing methods in our ECT conversion chart guide. . Such as the 17-40 Series Box Compression Tester, . Edge Crush Test (ECT): The Edge Crush Test, on the other hand, takes a distinct approach by focusing on the material strength of the corrugated cardboard itself.A small segment of the corrugated material is employed for testing purposes. The material is positioned vertically, and pressure is applied to the edge until deformation occurs.Understanding the difference between the Box Compression Test (BCT) and the Edge Crush Test (ECT) can help you make more informed decisions when selecting If you rely on shipping and packaging to transport your products, choosing the right cardboard box is essential so that your products arrive at their destination safely and in good condition.การพัฒนาโซลูชันการทดสอบสำหรับ Edge Crush Test (ECT) ของกระดาษแข็งลูกฟูก . . ECT Compression Testers รุ่น Bench-top มีจำหน่ายในขนาดความจุ 2.5kN - 10kN ขึ้นอยู่กับช่วง .
Edge Crush Test (ECT) for Box Strength. 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. The Edge Crush Test measures the vertical compression stretch along the edge of a package. This test focuses on compression and stacking strength. This test was developed around 1990 to provide a better measure of how well boxes will hold up during palletizing and vertically stacking. ECT is often looked at by customers who are concerned about . The edge compression streng th of corru gated board (ECT T APPI Methods 811, 838, 839) is routinely used as a pr imary measure of ship ping co ntainer board quality.
systems. For example, while 32 ECT is an ALTERNATIVE to 200 Burst, 32 ECT is not EQUIVALENT to 200 Burst. In fact, we would expect that 200 Burst would test about 38 ECT and 32 ECT would Burst test at roughly 150. If your primary concern is crushed boxes nd stacking problems, consider specifying in terms of ECT.This was despite the fact that these ‘recycled board’ cases still had very good compression and damage resistance qualities, as evidenced in the Edge Crush Test (ECT). The Mullen Burst Test measures the force required to puncture the face of corrugated board and is reported in pounds per square inch (psi), boards are thus rated accordingly . El Edge Crush Test (ECT) es un método estandarizado utilizado para medir la resistencia a la compresión del cartón corrugado. Esta prueba evalúa la capacidad del material para soportar cargas en su borde o borde del material. Se lleva a cabo aplicando una fuerza uniforme en el borde de una muestra de cartón hasta que se produzca el colapso. Fiberboard using the Clamp Method (Short Column Test)” (11), TAPPI T 841 “Edgewise Compressive Strength of Corrugated Fiberboard using the Morris Method (Short Column Test)”, TAPPI T 838 “Edge Crush Test Using Neckdown” (12), and FEFCO test Method No. 8 “Edgewise Crush Resistance of Corrugated Fiberboard.” The FEFCO method requires
