The annotation: in article the procedure of uncertainty evaluation of measurement of division factor of attenuator with help on the standard CV, based on the modelling approach is considered. By results of the analysis of the scheme of measuring apparatus and of the process of evaluation the modeling equation is worked out, formulas for calculation of relative standard uncertainties of type A and B, the relative total standard and expanded uncertainties of measurement of division factor of attenuator are received. The budget of uncertainty of measurement of division factor of attenuator is made; the analysis of dominating contributions of uncertainty is carried out.
Keywords: uncertainty of measurement, the standard, division factor, standard uncertainty, the total standard uncertainty, the expanded uncertainty, a reduction method
