Properties of water and aqueous systems: Metrological applications

Published

Author(s)

Daniel G. Friend, Allan H. Harvey

Abstract

Water and aqueous systems are widely used in metrology, which is a major focus of the National Institute of Standards and Technology (NIST). Standards such as those produced by IAPWS can be used to calibrate instruments and validate protocols. In this work, we review several activities at NIST in which research on water and aqueous systems is being applied to improve metrology. The projects include a new formulation for the viscosity of pure water, an examination of the effect of dissolved air on the density and refractive index of water, and utilization of ab initio quantum methods for calculation of thermodynamic properties of moist air as required in humidity standards.
