摘要：

The National Institute of Standards and Technology plans to cease production of its molality-based primary standards. Accordingly, this article describes the method for preparation of the molality-based primary standards that are traceable to the Systeme International d'Unites (SI) (International Standard for Units). The uncertainty components are listed and a sample calculation is provided.
