9.1.1 Scope

This method covers the laboratory determination, using a glass hydrometer, of the density, relative density (specific gravity), or API gravity of crude petroleum, petroleum products, or mixtures of petroleum and non-petroleum products, normally handled as liquids, and having a Reid vapor pressure (ASTM Method D 323, Test for Vapor Pressure of Petroleum Products, or IP 69, Vapour Pressure Reid Method) of 180 kilopascals (26 pounds) or less.

Values are measured on a hydrometer at convenient temperatures, readings of density being corrected to 15°C, and readings of relative density (specific gravity) and API gravity to 60°F, using international standard tables. With these same tables, values determined in any one of the three systems of measurement are convertible to equivalent values in either of the other two so that measurements can be made in the units of local convenience.
