Conduct Ring Crush Test Using Presto Ring Crush Tester

Conduct Ring Crush Test Using Presto Ring Crush Tester

In the paper packaging industry, there are certain types of quality tests conducted that will help you to evaluate the compression strength of paper and its related products. One of the crucial tests that should be conducted is the ring crush test. This quality test can easily be processed with the help of the Presto edge crush tester digital model.

The RCT/FCT/Edge Crush Tester Digital is reliable equipment for determining the crush strength of cardboard boxes and containers. The edgewise compression strength of paperboard is correlated with the ring crush test. To optimally test the ring crush strength of the paper board, you can easily take help from the Presto ring crush tester. Here we will discuss brief information about the ring crush test and how you can easily prepare the specimen for conducting this quality test. So, let us get started!

Introduction about ring crush test

The ring crush test correlates with the edgewise compression strength of the paperboard. The strength of the liner or fluting is tested in the ring crush tester machine in the machine direction and perpendicular to it. This quality test is comparable to the short-span compression test. During these tests, it is critical that the force applied to the specimen be perfectly perpendicular.

The results of this quality test will depend on the preparation of the specimen. To ensure accurate results with the help of this test, the specimen and the guides must be exactly parallel to ensure the precise determination of ring crush strength of the testing specimen. Compression resistance is measured by conducting a ring crush test, and this compression strength is thought to be related to the ultimate compression strength of a composite board built from the components. TAPPI Test Method T822 is used to conduct this quality test for paper and packaging.

Presto RCT/FCT/Edge Crush Tester Digital model is very helpful in the quality of the material by testing the strength and resistance of that material against compressive forces. There are many benefits you will get with Presto ring crush testerNow, let’s discuss its features and technical specifications.

Features of RCT/FCT/Edge Crush Tester digital model

The fiberboard shipping containers are usually prone to get damaged when they get subjected to high loads. Therefore, this will be considered to be the main reason for measuring the performance of these boxes that makes them worth using in shipping and transportation. Therefore, by testing edge crush strength, ring crush strength flat crush strengthyou will be able to deliver accurate products to your customers.

There are many features you will get with this digital ring crush testing instrument.

Technical Specifications of Presto edge crush tester

In a ring crush test, a compression force will be exerted on a specimen held in rings shaped holder and is placed between the two platens of the compression machine. The Presto RCT machine is very useful in measuring the maximum load sustained by the specimen in a specific period of time. Below we have listed the technical specifications of the digital model of this lab testing instrument.

  • Microprocessor-based display for accurate test results
  • Display for compression strength of test specimen
  • Separate fixtures for ring crush, edge crush, and flat crush test.
  • Highly accurate test results under a compression force
  • Strong gripping clamps.
  • Bright LED display
  • Inbuilt calibration facility
  • Feather touch controls

RCT/FCT/Edge Crush Tester reveals the crushing resistance in terms of Kg/Unit length.


 Optional Features: 

  • The computerized model also available 
  • A Digital model with a printer facility is also available.

With these features and technical specifications, you will be able to test the crushing resistance of materials. Now, let’s discuss how you can easily prepare the specimen for the ring crush test.

Steps to prepare specimen accurately for ring crush test

If you want to prepare the specimen accurately for the ring crush test, then you can follow the steps mentioned below.

  • First of all, cut a specimen from the sample using the ring crush test template.
  • Now take the Ring Crush Test Fixture and place the spacer provided with the fixture according to the thickness of the specimen.
  • After the placement of the spacer, slowly insert the cut specimen into the cavity given on the fixture.
  • This will form a ring of the specimen on the fixture. Your specimen for the Ring Crush Test is ready.

In this way, you can easily prepare the specimen for the ring crush test. If you want to perform another quality test like the edge crush test then you can also read the steps of preparing the specimen accurately for the edge crush test.
