Abstract

National Metrology Institutes from 6 African countries, namely Egypt, Nigeria, Zambia, Zimbabwe, Botswana, and Mauritius have participated in an international supplementary comparison on the calibration of pin gauges. This comparison was a part of larger supplementary comparison between 13 African countries for the calibration of hand measuring instruments. This larger comparison which was carried out during the period between December 2019 - December 2022 has been piloted by NIS, Egypt and has been registered in BIPM-KCDB database on December 2019. The artifacts have been prepared by NIS, Egypt and measured before sent to circulate between all participant countries in round-robin scheme and returned back again for NIS, Egypt where a final measurement is made for stability check. The main purpose of these comparisons is to support submission of CMCs for calibration of hand length measuring instruments in BIPM-KCDB. 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 CCL, according to the provisions of the CIPM Mutual Recognition Arrangement (CIPM MRA).

AFRIMETS 针规补充比较

来自埃及、尼日利亚、赞比亚、津巴布韦、博茨瓦纳和毛里求斯等 6 个非洲国家的国家计量机构参加了针规校准国际补充比对。这次比对是 13 个非洲国家之间校准手动测量仪器的大型补充比对的一部分。这项更大规模的比对在 2019 年 12 月至 2022 年 12 月期间进行，由埃及国家统计研究所进行试点，并于 2019 年 12 月在 BIPM-KCDB 数据库中注册。工件由埃及国家测绘局准备和测量，然后以循环方式在所有参与国之间分发，并返回埃及国家测绘局进行最后测量，以检查稳定性。这些比对的主要目的是支持在 BIPM-KCDB 中提交校准手长测量仪器的 CMC。要阅读本文正文，请点击最终报告。请注意，该文本是 BIPM 关键比对数据库 https://www.bipm.org/kcdb/ 附录 B 中的文本。根据 CIPM 互认安排 (CIPM MRA) 的规定，最终报告已由 CCL 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.
