Abstract: This paper focuses on the data processing modeling for reference materials preparation. By analyzing the data of reference materials (RMs), the process of repeatability and stability verification, uncertainty estimation, traceability of the value of a quantity and the characterization of RMs are detailed in the paper.

Abstract: On the basis of data gathered in connection with a certification project, problems were investigated that impair the accuracy of quantitative phase analyses (QPA) using the Rietveld method. Some mechanisms were elucidated by which insufficient counting statistics of the diffraction data or inappropriate data handling and refinement strategy influence the QPA results.
