Paper discusses the task of uncertainty evaluation of estimated physical values of national standards. In order to improve accuracy of the second phase of evaluation (calculation) of this task adaptive Monte-Carlo method is proposed for use. The latter showed high effectiveness for uncertainty evaluation of measurements results. By the example of uncertainty evaluation of estimated value of electrolytic conductivity of fluids national standard, effectiveness of the proposed method is proved.
