Description: The data of confidence limit error and expanded uncertainty calculation on the basis of the interlaboratory experiment results are given. The interlaboratory experiment was carried out by using of the set of six state standard samples ( CRM ) as examined samples. In fives independent results on each of six levels of all 14 elements represented in standard samples were got. Used state standard samples are stable synthetic mixtures of nickel oxides and elements-dashes, a powder of size 0,1 mm. The program STATISTICA was used for the calculations of statistical descriptions of the interlaboratory experiment.
Keywords: result of the analysis, the expanded uncertainty of result of the analysis, estimation standard deviations, repeatability conditions, reproducibility conditions, reference value
