The automatic relaxation and creep tester EB 32 is equipped with a liquid circulator for cooling and can cycle between -40 °C and +200 °C, with the same temperature in all 3 test stations. The EB 32 instrument perfoms tests according to ISO 188 method A, ISO 3384-1 method A and B, ISO 3384-2 method A and B, ISO 6914 method A, ISO 8013, and ISO 899-1 as well as ISO 899-2 with modified test specimen (no extensometer required).
By default the EB 32 is delivered with compression plates and 1000 N load cells. Other accessories such as different loadcells, testing in compression in liquid, testing in air in tension and special clamps for testing in creep according to ISO 899-1 and ISO 899-2 can be ordered separately.
If testing at 23 °C 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.
As the positioning is done by servo motors, the instrument will automatically compensate for the deformation in the load cells. The resolution of the position is 0,0001 mm and the accuracy 0,001 mm.
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.
The EC 13 Windows application, which is a part of the EB 32 automatic relaxation and creep tester, helps the user setup the test and it continuously displays the results.
Easy to change between test methods
Both testing methods, stress relaxation and creep uses the same accessories. The shifting between the two test methods is done when the EC 13 software is started. Changing between compression and tension consist of a simple rebuilding of the rigs, thoroughly described in the manual.
Note: For the best performance of the instrument, we recommend a placement in an environment with a stable temperature between +10 to +30 °C.
