Kappa LA-Spring

Lever arm testing machine with spring assembly for creep tests up to 100,000 hours

The versatile lever arm creep testing system with pretensioned spring was developed for classic creep tests with constant or stepped force application and long-term tests up to 100,000 hours. Wear-free flexible joints guarantee optimal lever arm mounting and precise force application in a wide load range.

Key Advantages and Features

Applications

The Kappa LA lever arm testing machine with pretensioned spring offers a wide range of applications:

  • Creep test
  • Creep test up to break:
    - Creep rupture
    - Stress rupture
  • Relaxation test
  • Crack growth/widening test
  • Determination of hydrogen embrittlement
  • Stepless load definition and load block tests possible
  • Ambient or high temperature
  • For long-term tests up to 100,000 hours

Advantages and Features

  • Wear-free flexible joints provide high-quality lever arm mounting and ensure Class 1 measurement accuracy in a measurement range from 1 to 100% of nominal force as per ISO 7500-2, while eliminating knife-edge problems during the entire service life of the machine.
  • Precise load and strain control
  • No friction, no wear, and constant force application
  • Maximum precision, maximum reliability and a long service life
  • Controlled lead screw drive maintains the lever arm in a horizontal position during the test
  • Axiality compensating links in the load axis

Materials Development through Creep Tests up to 1,600°C with the Kappa Series from ZwickRoell at the Institute of Physics of Materials (IPM)

As part of the Czech Academy of Sciences (CAS), the Institute of Physics of Materials (IPM) has studied the correlation between material properties and their microstructural characteristics at its location in Brno since 1955. Since the beginning, IPM has striven to continuously improve the properties of materials to achieve higher performance, safety, and reliability of technical systems.
