The ideal testing machine for tests in various environmental conditions

The flexible electromechanical creep testing machine Kappa DS is equipped with a double lead screw and was designed for classic and advanced creep tests. The large crosshead travel and the associated expanded test area provide sufficient space for temperature, vacuum or inert gas chambers for example, making this testing machine ideal for tests under various environmental conditions.

The Kappa DS 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 dual lead screw drive and precision guidance via four steel columns for precise axial loading
• Dual lead screw drive
• 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
