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

摘要: 分别从术语定义、计量性能要求、主标准器具、校准项目、校准程序等方面对比了JJG 556—2011和ASTM E467—2021中对于动态力计量溯源的技术差异。结果表明:JJG 556—2011中要求的动态力校准项目有6项,而ASTM E467—2021中要求的项目仅有2项;ASTM E467—2021的技术要求要高于JJG 556—2011。

Abstract: 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.
