Popis:	Metrological characteristics—precision, trueness, and accuracy—of the results of measurements of the exchangeable acidity and its components by the potentiometric titration method were studied on the basis of multiple analyses of the soil samples with the examination of statistical data for the outliers and their correspondence to the normal distribution. Measurement errors were estimated. The applied method was certified by the Metrological Center of the Uralian Branch of the Russian Academy of Sciences (certificate no. 88-17641-094-2013) and included in the Federal Information Fund on Assurance of Measurements (FR 1.31.2013.16382).
