Abstract

Uncertainty estimation results are presented for the intercept and slope of the deformation coefficient of a piston-cylinder set of a Budenberg pressure balance operating in the range of 16100 psi (111 MPa) by using the GUM approach and Monte Carlo simulation methods. A study of the influence of the correlation between quantities that define the deformation coefficient on the value of its uncertainty is shown. Monte Carlo simulations are done by using the commercial software <i>Crystal Ball</i>®.
