How to Prepare the Testing Specimen for the Edge Crush Test?

In the paper and packaging industry, corrugated boxes play a crucial role in delivering your products safely to the customers. The quality of corrugated boxes will depend on their edge-wise compression strength as well. Thus, you can easily make use of the Presto edge crush tester which is one of the ideal testing instruments to check the edge-wise compression strength of these boxes. This accurate testing instrument was designed by the experts at Presto and has been embedded with several advanced features that will let you take the edge crush test. Here we will discuss how you can easily prepare the testing specimen for conducting the edge crush test. But before that, let’s have a look at the information about the edge crush test and why it is useful in the packaging industry.

What is an edge crush test?

An edge crush test or ECT for corrugated boxes is one of the effective laboratory test methods used to measure the cross-section crushing of corrugated boxes. By conducting this quality test, you will be able to determine the ability of a material to withstand the compressive forces.

Whenever you perform an edge crush test, with the help of an edge crush tester digital model then a compressive sectional load will be applied on the corrugated box that measures the rigidity of the product edgewise. This highly advanced testing equipment will help you to evaluate the strength of boxes so that they can sustain real-life action. You can also evaluate the stacking strength of cartons with the help of an edge crush tester.

This lab testing instrument will measure the edges of boxes that are mostly responsible for bearing the loads. The edge crush testing machine will also be helpful in determining the edge crush strength of 3 ply corrugated boxes.

Furthermore, besides offering the exact value of the material’s resistance, the ECT test will allow you to determine the exact amount of corrugated cardboard that will ensure the goods’ protection, thereby optimizing the packaging. You can also evaluate the flat crush resistance of cardboard. 

The digital model of this crush resistance tester has been equipped with several advanced features. We have given the information about the features and the technical specifications of this lab testing instrument below.

Steps to prepare the testing specimen for edge crush tester

  1. Cut a rectangular piece of the specimen from the sample you want to test. You can consider this size 50 + 1 mm X 30 + 1 mm, for cutting the specimen.
  2. The specimen must be cut according to the dimension of the template given for the edge crush test provided with the machine.
  3. Now loosen the Allen bolts of the edge crush fixture provided with the machine with the help of an M-5 Allen key and insert the specimen between the fixtures and adjust the fixture gap according to the thickness of the sample.
  4. The specimen for the Edge crush test is ready.
