Abstract
The results of estimating the accuracy of spectral analysis of steel according to inter-laboratory comparative tests (ICT) conducted by JSC «ISO» to attest standard samples and examine qualification of the laboratories are considered. Data on the consistency of the results of spectral analysis and data of chemical methods and their comparison with analogous data of ICT of foreign standard samples are also presented.
