Automatic Creep and Relaxation Tester-EB 18 
• For stress relaxation tests 
• For creep tests 

With EB 18 automatic Creep and Stress Relaxation tests can be done. 
The instrument is based on our triple temperature oven EB 07, which 
means that each test station can run with an individual temperature. 
The test rigs are based on our relaxation rig EB 02, but lowering and
raising of the rigs is motor driven.
The compression or tension of the samples is also motor driven with 
a servo motor.
The test rigs are built into a plastic cabinet made of polycarbonate 
and aluminium profiles.
The cabinet is cooled by Peltier elements which keep a constant room 
temperature around the test stations.

主要特点：
Automatic Creep and Relaxation Tester-EB 18
• For stress relaxation tests
• For creep tests

With EB 18 automatic Creep and Stress Relaxation tests can be done.
The instrument is based on our triple temperature oven EB 07, which means that each test station can run with an individual temperature.
The test rigs are based on our relaxation rig EB 02, but lowering and raising of the rigs is motor driven.
The compression or tension of the samples is also motor driven with a servo motor.
The test rigs are built into a plastic cabinet made of polycarbonate and aluminium profiles.
The cabinet is cooled by Peltier elements which keep a constant room temperature around the test stations.

This design gives the following advantages:
For Creep tests
• Creep test can be done in both compression and tension.
• Utilising load cells and servo motors to apply and hold the load
the EB 18 tester, eliminates the handling problems associated with
dead load weights.
• The load in MPa or N is set in the software and the computer
instructs the closed loop circuit of the servo motor and load cell
amplifier to keep the set load. This means that the load is kept
even if the computer fails.
• High accuracy in the displacement measurement.
• Results are presented in graphical or table formats as absolute
creep or creep index. In order to study the actual sample failure
the data logging rate is increased just before break occurs.
• Possibility of running new features such as load and temperature
ramps controlled by the computer.
• Test can be made in liquids using a liquid container. (option)
• Versions with 3 to 10 test stations can be supplied.

For Stress Relaxation Tests:
• Relaxation tests can be done in both compression and tension.
• Utilising load cells and servo motors to apply and hold the
compression the EB 18, automatically compensates for the spring
effect in the load cells.
• The compression or tension in mm or % is set in the software and
the computer instructs the closed loop circuit of the servomotor
and load cell amplifier to keep the set value. This means that the
position is kept even if the computer fails.
• High accuracy in the displacement measurement.
• Results are presented in graphical or table formats as absolute
relaxation in N or as F/F0 in absolute or relative time as well
as linear or log time.
• Possibility of running new features such as load and temperature
ramps controlled by the computer.
• Test can be made in liquids using a liquid container. (option)
• Versions with 3 to 10 test stations can be supplied.
