Public Announcements

Publication Announcement – N15.51-2017, American National Standard for Methods of Nuclear Material Control - Measurement Control Program – Nuclear Materials Analytical Chemistry Laboratory.

This INMM ASC N15 standard provides the principal elements of a measurement control program for an analytical chemistry laboratory supporting nuclear fuel cycle activities. The ability to safely manage and to maintain accounts of these materials requires measurement of the materials as they are produced, used, shipped, stored, and inventoried. A comprehensive measurement control program demonstrates the reliability of the measurement data, quantifies the performance of the measurement system, assures that the measurements used in the nuclear industry are suitable for their intended use, and provides for detection and correction of adverse changes.  The revision adds guidance regarding the optional use of the ISO Guide to the Expression of Uncertainty in Measurement (GUM) to report analytical uncertainties.   This standard is now available for purchase through the ANSI webstore at
