Предложен математический аппарат и алгоритм действий для оценки стандартной неопределенности от нестабильности и срока годности стандартного образца. Рассмотрены подходы к оцениванию неопределенности от нестабильности в случаях отсутствия и наличия значимого тренда аттестованной характеристики стандартного образца во времени. Показано, что существует обоснование минимального количества измерений для исследования стабильности стандартного образца. Установлено, что сглаживание результатов измерений при оценке стабильности стандартного образца приводит к назначению завышенного срока годности.</p></abstract><trans-abstract xml:lang="en"><p>The present article presents comparative characteristics of domestic and international approaches to estimating the instability of reference materials, and describes the proposed changes in R50.2.031-2003. A mathematical apparatus and an algorithm of actions for estimating the standard uncertainty due to instability, and the shelf life of a reference material are proposed. Approaches to estimating the uncertainty due to instability in the cases of absence and presence of a significant trend in the certified characteristic of a reference material over time are considered. It is shown that there is a rationale for the minimum number of measurements to study the stability of a reference material. It has been established that the smoothing of the measurement results when estimating the stability of a reference material leads to the appointment of an overestimated shelf life. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>стандартная неопределенность от нестабильности</kwd><kwd>стандартный образец</kwd></kwd-group><kwd-group xml:lang="en"><kwd>standard uncertainty due to instability</kwd><kwd>reference material</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">Дрейпер Н., Смит Г.
