Abstract

This guide presents information that will assist with maintenance of the SI unit of mass at National Measurement Institutes. The information presented is primarily aimed at establishing the technical infrastructure and procedures that will allow the robust maintenance of a national mass scale following the redefinition of the kilogram. This guide gives information on the evaluation of different storage methods with a view to optimising the medium- and long-term stability of primary mass standards.
