Uncertainty in NIST force measurements.(National Institute of Standards and Technology)

From: Journal of Research of the National Institute of Standards andTechnology | Date: November 1, 2005| Author: | Copyright information

This paper focuses upon the uncertainty of force calibration measurements at the National Institute of Standards and Technology (NIST). The uncertainty of the realization of force for the national deadweight force standards at NIST is discussed, as well as the uncertainties associated with NIST's voltage-ratio measuring instruments and with the characteristics of transducers being calibrated. The combined uncertainty is related to the uncertainty of dissemination for force transfer standards sent to NIST for calibration.

Key words: calibration; deadweight force standard; ...
