tst / torsional stiffness test

  • laboratory equipment used to determine torsional stiffness in interaction with transverse shear,
  • TST is a device that is part of the BSE system – supports the process of identification of corrugated board material parameters,
  • TST is characterized by high sensitivity to crushing the cross-section of corrugated board in processes such as die-cutting, laminating, etc. – by performing a reference test (before the process) and control (after the process) it is possible to assess with great accuracy how a given process affects the material and thus how much the load capacity of the packaging is reduced,
  • static test consisting in twisting a sample of 150×50 mm by 10 degrees in both directions – the obtained result is stable even for very flaccid or heavily crushed cardboard,
  • advanced algorithms and precise measurement system allow to obtain accurate and reliable results,
  • parameters:
    • device dimensions: 180 x 230 x 300 mm,
    • device weight: 5 kg,
    • sample dimensions: 50 x 150 mm,
    • accuracy of force measurement: < 0.05 gr,
    • accuracy of displacement measurement: < 0.01 mm,
    • power voltage: 240V,
    • media: compressed air,
    • communication: USB.
