<p>This Technical Report gives the detailed evaluation of uncertainty for volume measurements according to the</p>
<p><i>Guide to the Expression of Uncertainty in Measurement </i>(GUM) [1]. It uses the gravimetric method specified in</p>
<p>ISO 8655-6 [2] as the reference method for calibrating piston-operated volumetric apparatus. It has been arranged</p>
<p>in paragraphs to facilitate direct access to different aspects of this kind of evaluation as follows:</p>
<p>_ modelling the measurement by describing the physical equations necessary to calculate the volume using the</p>
<p>gravimetric method of measurement;</p>
<p>_ determination of the standard uncertainty of measurement associated with the volume <i>V</i>20 by describing the</p>
<p>calculation procedure according to the GUM;</p>
<p>_ determination of the sensitivity coefficients with an example of the calculation of all sensitivity coefficients by</p>
<p>using complete equations, approximations of equations and by giving numerical values for standard</p>
<p>conditions;</p>
<p>_ determination of the standard uncertainty associated with the volume delivered by a piston-operated</p>
<p>volumetric apparatus giving the combination of the standard uncertainty associated with the volume <i>V</i>20</p>
<p>measured using the gravimetric measuring system and the experimental standard deviation associated with</p>
<p>the volume delivered by the apparatus;</p>
<p>_ determination of the standard uncertainties of measurement with a brief insight into the calculation of</p>
<p>uncertainties of measuring devices according to GUM;</p>
<p>_ determination of the expanded uncertainty of measurement associated with volume <i>V</i>20;</p>
<p>_ example of the determination of the uncertainty for volume measurements.</p>
