Abstract

The objective of the Pilot Study was the calibration of sub-multiples of the kilogram, which was organised as a EURAMET Pilot Study in order to demonstrate a diagnostic comparison for the developed and improved Calibration Measurement Capability (CMC), while realising the mass scale of the participating National Measurement Institutes (NMIs). Due to the instability of some weights a simplified method was used to evaluate the results. It compares the laboratory result for each weight with the reference value obtained by the fitted weighted trendline, including the correlation due to the Consensus Value. It was the first time that the method of subdivision of a decade has been compared among laboratories by comparing the individual mass differences of the design matrix. The aim of improving capabilities and realising the mass scale with uncertainties of 1/3 mpe of the OIML Class E₁ tolerance was achieved by the participating NMIs.

已开发和改进的大规模测量能力的试点研究比较

试点研究的目标是校准千克的子倍数，作为EURAMET试点研究组织，以展示开发和改进的校准测量能力（CMC）的诊断比较，同时实现参与的国家测量机构（nmi）的大规模规模。考虑到一些权重的不稳定性，采用了一种简化的方法来评价结果。它将每个权重的实验室结果与拟合的加权趋势线获得的参考值进行比较，包括共识值的相关性。这是十年来第一次通过比较设计矩阵的个体质量差异来比较实验室间的细分方法。通过参与的nmi实现了提高能力和实现不确定度为OIML E1级公差1/3 mpe的质量规模的目标。
