- Abstract:
- This paper presents the results obtained from density measurements of pure water produced at CENAM. This water is used as density standard for calibrations services.
The measurements were done into a scheme of experimental design in order to find possible sources of variability in the hydrostatic weighing system of the national density standard. The design factors checked were: days after the water is produced, positions of the solid density standards at the hydrostatic weighing system and the spheres used.
The variable of interest for the scheme of experimental design was the difference between the water density measured using the solid density standards and the water density calculated by the formula of M. Tanaka et al.
The goal of this study is to estimate an uncertainty value associated to the water density used at CENAM calculated by the formula which includes the storage effect, and by other side evaluating the effects due to the spheres and positions of the sphere into the hydrostatic weighing system of the national density standard. - Keywords:
