Axial alignment

• Central lead screw for precise axial alignment to ASTM E292
• Load string with optimal alignment properties in accordance with ASTM E1012
• Spherical mounting ensures self-adjusting alignment in tensile tests and low, standard-compliant flexural stress (± 10%)

Precise specimen temperature

• High-temperature furnace, temperature chamber or induction heating system – selection based on test temperature of type of test
• One, two or three specimen thermocouples – dependent on the specimen length
• Automatic and specimen-centered entrainment of the thermocouples and the furnace – also in case of long elongations and long test duration
• Operator-independent temperature control with automated adaptation of the control parameter for influencing factors such as
  - Heating rates and target temperature
  - Specimen size, material and shape
  - Number of thermocouples
• Guaranteed uniform temperature distribution along the specimen
• No overshooting of the specimen temperature upon reaching the target temperature
• Empirical determination of the control parameters for individual temperatures is no longer necessary
• Wide temperature range with tolerances better than ISO 204 and ASTM E139:
  200°C to 400°C: ± 2 K
  400°C to 1,150°C: ± 1 K

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

Optimal extensometer

Reliable strain measurement is based on an extensometer that has been optimally matched to the testing application. Therefore, selection of the right extensometer is crucial and is the basis for repeatable test results. ZwickRoell engineers are available to help you select the right extensometer for your application, eliminating any guesswork in deciding on an optical or contact-type extensometer:

• Non-contact extensometer videoXtens
• Side-attaching contact-type extensometer:
  -makroXtens with high-temperature sensors
  - Side entry extensometer
• Axial-attaching contact-type extensometer:
  - Rod-in-tube extensometer
  - 4-rod extensometer
• DCPD extensometer for measuring the crack growth

Wide range of accessories

The wide selection of machine accessories supports many application possibilities, allowing for testing with one and the same testing machine at ambient temperature, high temperature and ultra-high temperature.

• Furnaces with different dimensions and slots
• Temperature, vacuum and inert gas chambers
• Induction heating systems
• Specimen grips and load strings
• Contact-type and non-contact extensometers
• Safety enclosures
• Hot cell solutions

Ready for changes in future technology

Modular design means that the testing system can be converted or retrofitted whenever required. Moreover, testControl II machine electronics are compatible with future-generation ZwickRoell software.
