Considerations in mass calibration of pressure balance weights

Juan Benjamin Soriano Cardona, Manuel Segura Galindo

Abstract

A review of mass calibration of pressure balance weights was developed to explain in detail the considerations around the measurements of mass value determination of each weight applied on the pressure balance that use an accurate mathematical model by industrial and accredited laboratories.<br /> The mass value determination of each weight applied on the pressure balance is an important uncertainty contribution in the estimation of the uncertainty measurement of a pressure balance when used for the calibration of another measuring instrument and in the case where the total measurement uncertainty has to be of high level.<br /> There are different considerations have to be applied to take into account: calibration method of mass values, weights densities values, conventional mass, and estimation of the uncertainty measurement of mass value by whose that use a pressure balance that use an accurate mathematical model to improve the pressure measurement the best of possible.
