Elastocon EB 18-II-3 allows Relaxation and Creep Tester to be carried out
automatically.
The instrument has 3 test stations and an individual control of each test station as
well as the temperature of each cell. The test rigs are based on our relaxation rig
EB 02, but here the lowering and raising of the rigs as well as the compression or
stretching of the samples are motor driven by a servo motor.
The EB 18-II-3 instrument is, by default, delivered with compression plates, 1000 N
load cells, and with a temperature range between +40 to +200 °C. If testing at room
temperature is wanted, the test can be performed with the rigs in their raised
position in the hood instead of down in the cells of the oven.
Other accessories can be ordered separately, such as for testing in liquids, tension
or temperature range up to +300 °C (HT-version). Optional load cells range from
100 N to 2000 N, the latter is a high force option called EB 18-II-3HF.
The test rigs are built into a cabinet made of polycarbonate with aluminium
profiles, which provides the same temperature stability around the upper part of the
rigs as our other continuous relaxation test systems. The oven is one of our high
precision ageing ovens, and meets the international standard ISO 188 method A as
well as other technically equivalent standards.
Both testing methods, stress relaxation and creep uses the same accessories. The
shifting between the two test methods is done when the software is started. Changing
between compression and tension consist of a simple rebuilding of the rigs.
The instrument perform well according to ISO 188 method A, ISO 3384-1 method A, ISO
6914, ISO 899 with modification, and other equivalent standards.
