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

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.
