RS ISO/TR 20461: 2023
Determination of uncertainty for volume measurements of a piston-operated volumetric apparatus using a gravimetric method
Abstract

This document gives detailed information regarding the evaluation of uncertainty for the gravimetric
reference measurement procedure specified in ISO 8655-6[1]
and the gravimetric procedure specified
in ISO 8655-7:2022[1], Annex A, according to the ISO/IEC Guide 98-3[16].
This document also includes the determination of other uncertainty components related to the liquid
delivery process of a piston-operated volumetric apparatus (POVA), e.g. repeatability and handling.
Furthermore, it provides examples for the calculation and application of the uncertainty of the mean
delivered volume and the uncertainty in use of a single delivered volume.
