摘要

It is important to assess the metrological characterization of heavy-capacity weighing balances before using them, particularly when determining the volume of heavy-capacity volumetric tanks using the gravimetric method. In order to support industry with the best uncertainties in the corresponding range and enhance product quality, metrological properties of a heavy-capacity weighing balance of 30,000 kg were assessed using standard weights traceable to the National Standard of Mass. Only 7,000 kg weights of standard denominations that could be traced to the national standard were available; thus, a novel step-up method, which can be expanded to 50,000 kg, was employed in this characterization procedure. We have outlined a thorough procedure in this work that satisfies the requirements of the OIML R 76-1: 2006 standard as being economical and affordable.
