When performing creep tests, data are measurable indeed at such low shear rates which would cause problems in many cases if determined when using other test methods, or the corresponding test would take an extremely long time then. Data of creep tests are often used to characterize long-term behavior. They may be converted, for example from J(t)-values to frequency sweep values at very low frequencies (see Chapter 8.4. for details about frequency sweeps/oscillatory tests).
