Technical comparison of Chinese standard and American standard calibration methods for dynamic force of axially loaded fatigue testing machine

The technical differences of dynamic force measurement traceability in JJG 556-2011 and ASTM E467-2021 were compared from the aspects of terminology definition,measurement performance requirements, main standard instruments, calibration items and calibration procedures. The results show that there are six dynamic force calibration items required in JJG 556-2011, and only two items required in ASTM E467-2021. The technical requirements of ASTM E467-2021 are higher than JJG 556-2011.
