REEVALUATION OF CCM KEY COMPARISONS IN MASS METROLOGY BY THE MONTE CARLO METHOD

Sungjun Lee, J. W. Chung

Abstract

To provide insights for analysis of Key Comparisons (KCs), we have estimated previous KCs with Monte Carlo Simulation. Two similar previous KCs in mass metrology of 50 kg scale were taken in this work as the typical example. The KC Reference Value (KCRV) was evaluated with several popular estimators as well as median in this analysis. Their uncertainties were considered with Guide to the Expression of Uncertainty in Measurement (GUM) and numerical simulation by Monte Carlo Method (MCM).
