Влияние нулевой неопределенности международного прототипа килограмма на прослеживаемость измерений

Abstract

After a new redefinition of the kilogram, the International Prototype of Kilogram has its own uncertainty. The paper describes the impact of this uncertainty on the global traceability. The requirements OIML R 111-1 for weights are considered. The ability of laboratories to distribute mass at the level of accuracy classes E1 and E2 after redefinition is analyzed.
