This test determines the deformation behavior under long-term static tensile stress. Each of the specimens is subject to a different load remaining constant for some time while the deformation is measured simultaneously. The test may be carried out within a temperature range from +23 ºC to +150 ºC. The results can be used to estimate the deformation behavior of components that are exposed to long-term tensile stresses. Therefore this test method is particularly important for the design engineer.
Results of the test method:
The tensile-creep modulus, the isochronous stress-strain curve, the creep-to-rupture curve and the relaxation behavior can be determined from the creep curves.
