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.
