Provides cycle counting techniques and data reduction methods which are used in variable amplitude fatigue testing.

This part of ISO12110 presents cycle counting techniques and data reduction methods which are used in variable amplitude fatigue testing.

For each test or test series, cycle counting is mandatory whereas data reduction methods are optional.

This part of ISO12110 supports ISO12110-1 which contains the general principles and describes the common requirements about variable amplitude fatigue testing.

In this part of ISO12110, the term “loading?? refers either to force, stress, or strain since the methods presented here are valid for all.

The following issues are not within the scope of this part of ISO12110 and therefore will not be addressed:

  • constant amplitude tests with isolated overloads or underloads;

  • large components or structures;

  • environmental effects like corrosion, creep, etc. linked to temperature/time interactions leading to frequency and waveform effects;

  • multiaxial loading.

NOTE1 Phasing is of prime importance when dealing with multiaxial tests under either constant or variable amplitude controlled loading.

NOTE2 Although frequency variations during cycling are not outside of the scope of this part of ISO12110, the following clauses deal only with constant frequency cycling.
