Abstract
A new set of certified reference materials (CRM) of alloyed cast irons CHG50 – ICRM CHG55 has been developed in 2017 at the Institute for Certified Reference Materials. Novel technology thus used provided optimal use of the CRM volume. Special experiment was carried out to evaluate the contribution of heterogeneity to the total uncertainty of CRM. Study of the compatibility of the certified characteristics of the new set with the values of previously released cast irons sets revealed the possibility of using cast iron set CHG50 – CHG55 in x-ray fluorescence and atomic emission spectrometers.
