1.1 This practice covers the procedure for the performanceof axial force controlled fatigue tests to obtain the fatiguestrength of metallic materials in the fatigue regime where thestrains are predominately elastic, both upon initial loading andthroughout the test. This practice is limited to the fatiguetesting of axial unnotched and notched specimens subjected toa constant amplitude, periodic forcing function in air at roomtemperature. This practice is not intended for application inaxial fatigue tests of components or parts.
