The ideal testing machine for force and strain controlled long-term tests

The versatile lever arm creep testing system with pretensioned spring was developed for classic and advanced 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.

The Kappa LA Spring lever arm creep testing machine offers a wide range of applications in ambient and high-temperature conditions:

  • Crack growth/widening tests
  • Determination of hydrogen embrittlement
  • Stepless load definition and load block tests possible
  • Relaxation tests
  • Creep tests up to break:
    - Creep rupture
    - Stress rupture
  • Classic creep tests

Specific machine design

  • Mechanical testing system for long-term creep tests up to 100,000 hours
  • The combination of the pretensioned spring, the drive and the precise Xforce load cell from ZwickRoell ensures smooth application of the test load.
  • High drive control frequency of 1000 Hz. This allows for precise force and strain control for a wide range of applications.
  • Patented wear-free flexible joints ensure high-quality lever arm mounting.
  • 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
  • Automatic end of test after specimen break (break detector)

Axial alignment

  • Alignment to ASTM E1012
  • Wear-free flexible joints contribute to axial alignment according to ISO 204, ASTM E139, ASTM E292 and NADCAP requirements
  • Spherical mounting ensures self-adjusting alignment in tensile tests and low, standard-compliant flexural stress (± 10%)

Intelligent electronics and software

  • Consistent workflow orientation reduces training needs to a minimum
  • Strain and force controlled load application (stepless/in blocks)
  • Selectable digital closed loop force, stress and strain controlled creep tests and stress relaxation tests, as well as user-defined load cycles
  • Easy operation during test performance and test result evaluation
  • Integrated temperature control of the high-temperature controller
  • Temperature control, recording and documentation prior to the test (heating phase)
  • Well designed data security concept
