Abstract
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.
