The units for mass, voltage, resistance, and electrical current in the SI
Autor: Dean G. Jarrett, Zeina J. Kubarych, Randolph E. Elmquist, Patrick J. Abbott, Stephan Schlamminger
Publikováno v: IEEE Instrumentation & Measurement Magazine. 22:9-16
On May 20, World Metrology Day 2019, the international system of units (SI) underwent a momentous change. The philosophy behind the unit system was altered by replacing the former definitions that rely on seven base units with seven defining physical

Small mass realization in the new SI
Autor: Edward Mulhern, Stephan Schlamminger, Frank Seifert, Patrick J. Abbott, David B. Newell, L. S. Chao, Darine Haddad, Zeina J. Kubarych
Publikováno v: 2020 Conference on Precision Electromagnetic Measurements (CPEM).
On November 16 2018, about 60 countries met in Versailles, France and voted to redefine the System of Units(SI) based on seven defining reference constants. Since May 20 2019, the unit of mass is realized based on three fundamental reference constant

Parameter Identification in a Magnetic Suspension Force Transduction System
Autor: Corey Stambaugh, Nicholas Vlajic, Patrick J. Abbott
Publikováno v: Journal of Dynamic Systems, Measurement, and Control. 141
In force transduction systems, magnetic suspension can be used to facilitate the measurement of a force acting between two objects in different environments, namely, between the force transducer in one environment and the test object in another envir

The NIST Mise en Pratique for the Realization and Dissemination of the Kilogram as Part of the 'New SI'
Autor: Zeina J. Kubarych, Eric C. Benck, Patrick J. Abbott, Edward Mulhern, Corey Stambaugh
Publikováno v: NCSLI Measure. 11:45-50
The International System of Units (SI) will be redefined in 2018 so that the present seven SI base units are realized by a set of defining constants having exact values. For the unit of mass, the k...

Air–vacuum transfer; establishing traceability to the new kilogram
Autor: Kilian Marti, Lars Nielsen, James Berry, Andrea Malengo, Patrick J. Abbott, Stuart Davidson, Richard G. Green
Publikováno v: Metrologia. 53:A95-A113
The redefinition of the kilogram, along with another four of the base SI units, is scheduled for 2018. The current definition of the Si unit of mass is via the International Prototype Kilogram which is maintained and dissemination in air. The new def

Mass Calibration at NIST in the Revised SI
Autor: Patrick J. Abbott
Publikováno v: NCSL International Workshop & Symposium Conference Proceedings 2018.
The unit of mass has been realized by the International Prototype Kilogram (IPK) for over 130 years. This will change very soon. The revision of the International System of Units (SI) that will take effect on May 20, 2019 will fundamentally change th

Progress on vacuum-to-air mass calibration system using magnetic suspension to disseminate the Planck-constant realized kilogram
Autor: Zeina J. Kubarych, Corey Stambaugh, Patrick J. Abbott, Edward Mulhern, Eric C. Benck
Publikováno v: Acta IMEKO (2012)
The kilogram is the unit of mass in the International System of units (SI) and has been defined as the mass of the International Prototype Kilogram (IPK) since 1889. In the future, a new definition of the kilogram will be realized by fixing the value

The New Kilogram Definition and its Implications for High-Precision Mass Tolerance Classes
Autor: Zeina J. Kubarych, Patrick J. Abbott
Publikováno v: Journal of Research of the National Institute of Standards and Technology
The SI unit of mass, the kilogram, is the only remaining artifact definition in the seven fundamental units of the SI system. It will be redefined in terms of the Planck constant as soon as certain experimental conditions, based on recommendations of
