Evaluation of Measurement Uncertainty for the Determination of Calcium Oxide in Protective Slag by X-ray Fluorescence Method
According to the uncertainty evaluation method of JJF 1059.1-2012 and referring to CSM 01 010108-2006,this article evaluates the"uncertainty caused by sample preparation","repeatability of multiple measurement results","variability of working curve","uncertainty of standard substance standard value"and"uncertainty of variability caused by high and low standard correction"in the process of X-ray fluorescence spectroscopy for determining calcium oxide,and analyzes the sources of their uncertainty contributions.
