TMI Büchel S Tester 17-38

A new flat crush tester

Brought to you by TMI Büchel -Buchel, the S Tester 17-38 offers a new method of crush resistance inspection as an alternative to Concora Medium Testing. When you need to carry out an efficient flat crush test of corrugated board that aligns with TAPPI standards, be sure to explore our innovate S Tester. 

The CMT test is time-consuming and easy to influence, so the results aren’t reliable. They can be impacted during sample handling, preparation, or by the operator. Then you’ve got factors including leaning flutes or improper tape adhesion to consider.  

What’s a flat crush resistance S-Test?

The 17-38 S-Test will help you to better predict the performance of your corrugated board. It was established to measure the compressive strength of the flute or medium of a sample, as a direct replacement for the CMT test.  

Enjoy operator-free flat crush resistance testing. Simply place your samples between the clamps and press start!  

During an S-Test a sample of non-corrugated medium is placed between two clamps. An offset between the clamps of 1mm compresses the flute to form an ‘S’ shape during the test. The test result is the maximum compressive force. The S-Test can be correlated to the first plateau of the CMT, ensuring you receive the flat crush test of corrugated board you’re looking for. 

A flat crush tester that correlates with CMT

The S-Test flat crush resistance test has shown a correlation coefficient of 97.6% with the first plateau of the CMT. So, it’s true! The results of the S-Test can be used to replace the CMT test, offering you a simple alternative flat crush test.  

GraphMasterProTM (optional) 

GraphMasterProTM is a PC data collection program capable of providing curve analysis and data storage. GraphMasterPro can also be used to give you improved control over your instrument.  

Cooperative development 

The S-Test was developed by TMI Büchel -Buchel with Smurfit Kappa. The Cepi Container Board and the Technical University of Darmstadt helped to test and prove the correlation with CMT.  

Flat crush and corrugated testing with Industrial Physics

In today’s world of strict standards and high demands, the data needed to assess whether a product meets customer specifications is essential.  

We make a wide range of paper and cardboard testing devices and accessories. Have a look at the TMI Büchel -Buchel – Short Span Compression Test (SCT, STFI): 500N 17-36. It measures the compression strength of paper and board.  

Another great product we proudly build is the Crush Tester 17-56. The Crush Tester is suitable for lots of samples, including corrugated board, tubes and plastics. It is a robust machine that tests to TAPPI T 825 standards. 

There’s no compressing our expanding insight!

We like to share the lessons we’ve learned over many decades of making paper testing and cardboard testing devices. Whether you need help with flat crush testing or you’re looking for other insight into corrugated and paperboard tests, we’re sure to have something to help.
