Scope: This document specifies the terms and definitions, principles, specimens, test equipment, and test procedures for ultrahigh-cycle fatigue and ultrasonic fatigue testing of metal materials. This document applies to circular or rectangular cross-section specimens of metal materials, with a test frequency of 2.00×104 Hz ± 500 Hz, single-end axial excitation, and a stress ratio of R = -1 for ultrahigh-cycle fatigue testing. This document does not include notched specimens, but the fatigue testing process described in this document can be applied to notched specimens for ultrahigh-cycle fatigue testing, as well as to ultrahigh-cycle fatigue testing with other stress ratios or ultrasonic resonance frequencies.
