This publication is intended to encourage a uniform approach to volumetric and mass calculation of crude oil, petroleum products, and petrochemicals when measured by meters. It also addresses calculation sequences, rounding, and significant digits, with the aim that different operators can produce identical results from the same observed data.
This publication applies to fluids that, for all practical purposes, are considered to be Newtonian, single-phase, and homogenous at metering conditions. Most fluids and dense phase fluids associated with the petroleum and petrochemical industries are considered to be Newtonian. The application of this standard is limited to fluids that utilise appropriate density and volume correlations.
