Scope:

This document refers to temperature volume correction factors, which allow users to convert volumes, measured at ambient conditions, to those at reference conditions for transactional purposes. This document also refers to compressibility factors required to correct hydrocarbon volumes measured under pressure to the corresponding volumes at the equilibrium pressure for the measured temperature

Table 1 shows the defining limits and their associated units of correction factors referenced in this document for crude oil, refined products and lubricating oils. These values are shown in bold italics. Also shown in the table are the limits converted to their equivalent units (and, in the case of the densities, other base temperatures). Table 2 shows defining limits of correction factors for light hydrocarbons (natural gas liquids and liquefied petroleum gases).

This document excludes specifying standard reference conditions for natural gas which are given in ISO 13443[15].
