Abstract

Main textThis is the final report for APMP supplementary comparison APMP.AUV.V-S1 in the area of 'vibration' (quantity of rotational speed). The aim of this comparison was to compare primary measurements of rotational speed in the range from 10 r/min to 99 999 r/min. Two Metrology Institutes from APMP have participated in the comparison with National Institute of Metrology, P.R. China as pilot lab. Both laboratories used mechanical generators as standard equipment and provided their calibration results, which were all consistent within their declared expanded uncertainties for the measurement results except for 10 r/min. Both participants contributed to the SCRVs calculated for thirteen rotational speed comparison values. NMC was not consistent within their declared expanded uncertainties at 10 r/min. Further improvements of their calibration devices and uncertainty evaluations will provide more accurate and reliable measurement results in the future.To reach the main text of this paper, click on Final Report. Note that this text is that which appears in Appendix B of the BIPM key comparison database https://www.bipm.org/kcdb/.The final report has been peer-reviewed and approved for publication by the CCAUV, according to the provisions of the CIPM Mutual Recognition Arrangement (CIPM MRA).

APMP.AUV.V-S1最终报告：使用机械发生器校准激光转速计的补充比较

正文这是APMP补充比对APMP.AUV.V-S1在 "振动"（转速量）领域的最终报告。此次比对的目的是比对10 r/min至99 999 r/min范围内转速的主要测量值。APMP 的两家计量研究所参与了此次比对，中国国家计量科学研究院作为试点实验室。两家实验室均使用机械发生器作为标准设备，并提供了校准结果，除 10 r/min 外，其他测量结果均在其宣布的扩大不确定度范围内。两家实验室都参与了 13 个转速比对值的 SCRV 计算。NMC 在 10 r/min 时的测量结果在其申报的扩展不确定度范围内不一致。对其校准装置和不确定度评估的进一步改进将在未来提供更准确、更可靠的测量结果。要阅读本文正文，请点击最终报告。请注意，本文是 BIPM 关键比对数据库附录 B 中的内容 https://www.bipm.org/kcdb/.The 根据 CIPM 互认安排 (CIPM MRA) 的规定，最终报告已由 CCAUV 进行同行评审并批准出版。

期刊介绍： Published 6 times per year, Metrologia covers the fundamentals of measurements, particularly those dealing with the seven base units of the International System of Units (metre, kilogram, second, ampere, kelvin, candela, mole) or proposals to replace them. The journal also publishes papers that contribute to the solution of difficult measurement problems and improve the accuracy of derived units and constants that are of fundamental importance to physics. In addition to regular papers, the journal publishes review articles, issues devoted to single topics of timely interest and occasional conference proceedings. Letters to the Editor and Short Communications (generally three pages or less) are also considered.
