Crude petroleum and petroleum products — Compressibility factors for hydrocarbons in the range 638 kg/m3 to 1 074 kg/m3

Pétrole brut et produits pétroliers — Facteurs de compressibilité des hydrocarbures dans la plage de 638 kg/m3 à 1074 kg/m3

This edition has been replaced by ISO 91:2017.

Abstract / scope

Includes the contents of Manual of Petroleum Measurement Standards, Chapter 11.2.1M published August 1984 by API. The purpose is to correct hydrocarbon volumes metered under pressure to the corresponding volumes at the equilibrium pressure for the metered temperature. Contains compressibility factors related to meter temperature and density of metered material.
