Description / Abstract:

This standard specifies requirements for the load-controlled fatigue test used to determine characteristic values which describe the behaviour of metallic materials and components under cyclic loading at constant amplitudes (Wöhler test).

This standard includes the test procedure, test evaluation, and documentation for load controlled tests in the high cycle fatigue and long life fatigue regime between 104 and 107 cycles. The extrapolation of S-N curves (or Wöhler curves, ge: Wöhlerlinien) beyond the experimentally documented range, particularly for S-N curves of type III (also see Clause 4) is outside the scope of this standard. This standard provides an S-N curve with a failure probability of 50 % as well as S-N curves with a failure probability between 10 % and 90 %.

This standard makes sole use of the log-normal distribution for the evaluation of the test results.

This standard does not cover strain or shear controlled tests (low-cycle fatigue or “LCF”).
