This creep testing machine meets the highest requirements on precise axial alignment

The Kappa SS creep-testing machine is equipped with a central lead screw and is suitable for classic and advanced creep tests that require maximum precision in force control and axial alignment.

The Kappa SS electromechanical creep testing machine offers a wide range of applications in ambient and high-temperature conditions:

• Advanced creep tests
  - Fatigue tests in the tensile range
  - Strain modeling (e.g. determination of creep curve at different loads)
  - Creep ductility
  - Creep test with slow strain rates (SSRT)
  - Creep data from components tests
• Crack growth and widening tests
• Determination of hydrogen embrittlement
• Tests with stepless force and temperature adjustment
• Relaxation tests
• Creep tests up to break
• - Creep rupture
  - Stress rupture
• Classic creep tests
• Short-term tensile, compression and flexure tests can also be performed with this testing machine

Specific machine design

• Load frame with central lead screw drive and precision guidance via four steel columns for precise axial loading
• Central lead screw for precise axial alignment
• High drive control frequency of 1000 Hz. This allows for precise force and strain control for a wide range of applications.
• High-resolution force and travel measurement for optimum control properties, especially at very low test speeds
• Precise loading rate with tolerance of ± 0.1 % of the set speed in the measurement range of 1 μm/h to nominal speed, unloaded or under constant load
• Wide force measurement range for tests with small and large forces according to DIN EN ISO 7500-1 in class 0.5 and class 1
• Precision testing machine to DIN EN ISO 7500-1
