This report describes a bilateral EURAMET supplementary comparison on Rockwell hardness scales of two national metrology institutes of Italy and Turkey, INRiM and UME, respectively. The pilot laboratory is INRiM in the comparison where three sets of hardness reference blocks for the Rockwell hardness scales of HRA, HRBW and HRC were used. Each set of blocks consists of four hardness reference blocks for HRA and HRBW and five blocks for HRC hardness scales. The comparison was realized as planned in the Technical Protocol with some delay. The measurement results and uncertainty assessments declared by INRiM and UME are in consistency with each other. == Main text To reach the main text of this paper, click on Final Report [https://www.bipm.org/utils/common/pdf/final_reports/M/H-S1/EURAMET.M.H-S1.a.b.c.pdf] .

洛基硬度标度（HRA-HRBW-HRC）中的INRiM和UME的EURAMET补充比较-EURAMET.MH-S1.abc

该报告描述了分别对意大利和土耳其的两个国家计量机构INRiM和UME进行洛氏硬度标度的双边EURAMET补充比较。比较中的中试实验室为INRiM，其中使用了三组用于HRA，HRBW和HRC的洛氏硬度标度的硬度参考块。每组块由用于HRA和HRBW的四个硬度参考块和用于HRC硬度标度的五个块组成。比较是按《技术议定书》的计划实现的，但有所延迟。INRiM和UME宣布的测量结果和不确定性评估彼此一致。==正文要访问本文的正文，请单击最终报告[https://www.bipm.org/utils/common/pdf/final_reports/M/H-S1/EURAMET.MH-S1.abcpdf] 。
