Проанализированы достоинства и недостатки существующего алгоритма оценивания расширенной неопределённости измерений, описанного в действующих нормативных документах. Исследованы особенности оценивания неопределённости при калибровках средств измерений и возможность применения метода эксцессов для расчёта неопределённости. Предлагаемый подход применён для примеров, описанных в Дополнении 2 к документу Европейской организации по аккредитации ЕА-4/02 М:2013.</p></abstract><trans-abstract xml:lang="en"><p>The influence of the law of distribution of the measurand on the length parameter for a guard band when assessing compliance is considered. The existing algorithm for expanded measurement uncertainty evaluation described in the current regulatory documents and its shortcomings is analyzed. The features of uncertainty evaluation in calibrations and the possibility of using the kurtosis method for its implementation are investigated. The proposed approach is applied to the examples described in Supplement 2 to the EA-4/02 M:2013.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>калибровка</kwd><kwd>оценка соответствия</kwd><kwd>расширенная неопределённость</kwd><kwd>метод эксцессов</kwd><kwd>calibration</kwd><kwd>conformity assessment</kwd><kwd>expanded uncertainty</kwd><kwd>kurtosis method</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zakharov I., Neyezhmakov P., Botsiura O., Measurement Science Review, 2017, vol. 17, no. 6, pp. 269-272. https://doi.org/10.1515/msr-2017-0034</mixed-citation><mixed-citation xml:lang="en">Zakharov I., Neyezhmakov P., Botsiura O., Measurement Science Review, 2017, vol. 17, no. 6, pp. 269-272. https://doi.org/10.1515/msr-2017-0034</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Efremova N.
