Abstract

Methods of spectral analysis are widely used on the production of aluminum alloys to determine the chemical composition of the melted material. For calibration of spectrometres are used certified reference materials (CRMs) of alloy composition. Uncertainty of certified values of CRM significantly affect on the accuracy of quantitative analysis. The uncertainty of the inhomogeneity of CRM is one of the total uncertainty of CRM certified value is. FSUE «VIAM» develops and produces certified reference materials. In this work we present the results of a study of the material composition of the alloy blanks CRM D16 melted on two different technologies. According to the research selected the technology that provides the best performance of the material CRM. Carry out the chemical analysis of CRM
