This report describes the method and results of a bilateral EURAMET Key Comparison in Vickers hardness scales of two National Metrology Institutes (NMIs) of Italy and Turkey, INRiM and UME, respectively. The Pilot Laboratory (PL) is INRiM in the comparison in which one set of hardness reference blocks with three hardness levels for the Vickers Hardness scales of both HV1 and HV30 was used. The comparison was realized as planned in the Technical Protocol with some delay. The aim of this comparison is to link the UME measurement results to the CCM.H-K1.b.c through the PL (INRiM) as a participant of the CCM key comparison. The measurement results and uncertainty assessments declared by INRiM and UME are in consistency with each other and UME results are also in consistency with the CCM.H-K1.b.c Key Comparison Reference Values (KCRVs). The CCM.H-K1.b.c was realized during 2001 to 2003 to investigate the metrological equivalence of national standards among national metrology institutes (NMIs) within the CCM.

本报告描述了意大利和土耳其的两个国家计量研究所 (NMI)、INRiM 和 UME 的维氏硬度标度双边 EURAMET 关键比较的方法和结果。中试实验室 (PL) 是 INRiM，在比较中使用了一组具有三个硬度级别的硬度参考块，用于 HV1 和 HV30 的维氏硬度标度。比较是按技术协议中的计划实现的，但有一些延迟。此比较的目的是作为 CCM 密钥比较的参与者，通过 PL (INRiM) 将 UME 测量结果链接到 CCM.H-K1.bc。INRiM 和 UME 声明的测量结果和不确定性评估相互一致，UME 结果也与 CCM.H-K1.bc 关键比较参考值 (KCRV) 一致。CCM.H-K1.b。
