Are you looking at performing the edge crush test and obtaining a certified Edge Crush Test box? But searching for a reliable Lab testing Instrument for this test can be challenging. So, Testronix is here to help you!

The ECT or Edge Crush Test measures the ability of corrugated cardboard that offer safety to goods during storage or transportation. It plays an important role in Paper and packaging industry as it helps to evaluate the compression forces a box can bear so as to provide safety to the goods and products.

In this blog, we will discuss the significance of performing edge crush test with the help of edge crush tester in the packaging industry.

What is An Edge Crush Test?

In the Industries like Paper and packaging, ring crush test (RCT), the flat crush test (FCT), the edge crush test (ECT) methods are used to measure the cross-section crushing of corrugated cardboard.

This test offers the necessary information regarding the ability of corrugated cardboard against crushing forces. It helps to manufacture boxes, packages and other products taking into account the material’s protective capabilities. In other words, this test provides the information of box’s strength and resistance to the crushing forces.

Advantages of Edge Crush Tester

This laboratory testing instrument for cardboard manufacturers to perform a quality control, and to test the protective ability of their raw material.

The advantage of Edge Crush Tester Digital is that it recognizes the safety measures of a box for transport goods. It becomes possible to determine the exact amount of weight or force a corrugated cardboard can bear. In other words, it will ensure the protection of goods for a quality result.

Now, let us discuss the working of edge crush tester.

Working of edge crush tester

Before commencing the edge crush test, it's crucial to ensure the proper placement of the specimen for accurate and reliable results.

Once the specimen is correctly positioned, follow these steps to conduct the test:

  • Initiate by pressing the RESET and TARE buttons to zero the peak load indicator.

  • Turn the rotary switch ON, directing it towards the UP position.
  • As the rotary switch activates, proceed to elevate the lower compression plate, applying compressive force onto the specimen.

  • Upon compression initiation, observe the load indicator's value increment.
  • When the load value reaches a certain point, switch the rotary switch to the OFF position to halt the machine.

  • Following machine cessation, the display will present the load value before returning to zero.
  • The deflection display will freeze, at which point, press the memory switches on the load indicator to reveal the peak value.
  • Record the displayed values from the load indicator for documentation.

In this way, you can easily commence the test. You can easily maintain the edge crush tester with the help of this quality testing instrument. If you want to know more about this testing instrument like edge crush tester price, etc. then you can give us a call at +91 9313 140 140 or email us at
