3 Terms and definitions

This standard applies the terminology and definitions GOST ISO 5725−1 and GOST 8.010.

4 the essence of the method

The analysis method is based on excitation of atoms of the sample in inductively coupled plasma and measuring the intensity of analytical lines defined element when spraying pre-translated in the sample solution in the plasma. The relationship of the intensity of lines with the concentration of the element in the solution set by using the calibration characteristics.

The method allows to determine the mass fraction of impurities in the ranges given in table 1.

5 Accuracy (trueness and precision) of the method

5.1 indicators of the accuracy of the method

Indicators of accuracy of the method: limit of the interval in which with probability P=0,95 is the absolute error of the results of the analysis standard deviation of repeatability , standard deviation of intermediate precision , the values of the limit of repeatability r, the limit of intermediate precision and reproducibility limit depending on the mass fraction of the element-impurities are shown in table 2.
