In 1975 Subcommittee ANSI-INMM-8, Calibration Techniques for Nuclear Material Control under the guidance of the American National Standards Institute Committee N15 and sponsored by the Institute of Nuclear Materials Management, published four standards for calibration of bulk measurement of nuclear materials. The calibration techniques include those for mass, volume, nondestructive assay, and plutonium calorimetry measurements. Since that time, calibration and research personnel of the Rocky Flats Plant and workers at other facilities have applied the direction and guidance of these standards. Results of the applications are reported and th value of each standard discussed. Examples are included together with certain shortcomings and future revision plans.
