Сличения национальных первичных эталонов стимулируют глубокое и детальное изучение факторов, влияющих на неопределённость измерений. Внесение калибровочных возможностей метрологических институтов в базу данных Международного бюро мер и весов позволяет проводить калибровку средств измерений, признаваемую всем мировым сообществом. В статье приведены результаты сличений национальных первичных эталонов твёрдости по шкалам Виккерса и Бринелля метрологических институтов стран, входящих в Евро-Азиатское сотрудничество государственных метрологических учреждений (KOOMET). Сличения проведены в рамках деятельности технического комитета по массе и связанным величинам ТК 1.6, шифр темы – 341/RU/05. Описана процедура региональных ключевых и дополнительных сличений национальных первичных эталонов твёрдости по шкалам Бринелля и Виккерса. По результатам сличений лабораториям, участвовавшим в сличениях, рекомендованы значения расширенных неопределённостей измерений, которые можно внести в базу данных Международного бюро мер и весов.</p></abstract><trans-abstract xml:lang="en"><p>The determination and confi rmation of the calibration measurements capabilities of national metrological institutes is necessary for the verification of the estimated metrological characteristics of the primary standard machines of these institutes. The passage of national primary standards through the comparison procedure encourages a deep and detailed study of the factors that affect the uncertainty of measurements. Adding the calibration capabilities of metrological institutes to the database of the International Committee of Weights and Measures (hereinafter referred to as the CIPM) allows for calibration of measuring instruments, which is recognized by the entire world community. The article presents the results of comparisons of national primary hardness standards on the Vickers scale and on the Brinell scale between the metrological institutes of the countries that are members of the Organization of Euro-Asian Cooperation of state Metrological Institutions (СOOMET). The comparisons were carried out within the framework of the technical committee on Mass and Related quantities TC 1.6, subject code – 341/RU/05. The article describes the procedure for conducting regional key and additional comparisons of national primary hardness standards on the Brinell and Vickers scales. Based on the results of the comparisons, recommendations are given to the laboratories that participated in the comparisons about the extended measurement uncertainties that they can enter into the database of the International Committee of Weights and Measures.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>национальный первичный эталон</kwd><kwd>шкалы твёрдости Бринелля</kwd><kwd>шкалы твёрдости Виккерса</kwd><kwd>ключевые сличения</kwd><kwd>калибровочные и измерительные возможности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>national primary standard</kwd><kwd>Brinell hardness scales</kwd><kwd>Vickers hardness scales</kwd><kwd>key comparisons</kwd><kwd>calibration and measurement capabilities</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">Дойников А.
