Standard test method for density, relative density (specific gravity), or API gravity of crude petroleum and liquid petroleum products by hydrometer method
This method covers the laboratory determination, using a glass hydrometer, of the density, relative density (specific gravity), of API gravity of crude petroleum, petroleum products, or mixtures of petroleum and nonpetroleum products normally handled as liquids, and having a Reid vapor pressure (Method D 323, or IP 69) of 26 lb or less. Values are measured on a hydrometer at convenient temperatures, reading of density being reduced to 15/sup 0/C, and readings of relative density (specific gravity) and API gravity to 60/sup 0/F, by means of international standard tables. By means of 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 may be made in the units of local convenience.
