scope:

This part provides standardized calculation methods for the quantification of liquids and the determination of base prover volumes under defined conditions, regardless of the point of origin or destination or units of measure required by governmental customs or statute. The criteria contained in this document allows different entities using various computer languages on different computer hardware (or manual calculations) to arrive at identical results using the same standardized input data.

This document also specifies the equations for computing correction factors, rules for rounding, including the calculational sequence, and discrimination levels to be employed in the calculations. No deviations from these specified equations are permitted, since the intent of this document is to establish a rigorous standard.
