Crude petroleum and petroleum products — Compressibility factors for hydrocarbons in the range 638 k...
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.
Aluminium ores — Determination of the moisture content of bulk material
Applies to the samples taken from bulk aluminium ores. Annex A specifies a method to be used when it is difficult to carry out sieving, crushing and dividing owing to the sample being adhesive or excessively wet. Annex B specifies methods of correction for sprayd water and/or rainfall.
