Standard Test Method for API
Gravity of Crude Petroleum and Petroleum Products (Hydrometer Method)
1.1 This test method covers the determination by means of a glass hydrometer of the API gravity of crude petroleum and petroleum products normally handled as liquids and having a Reid vapor pressure (Test Method D-323) of 26 psi (180 kPa) or less. Gravities are determined at 60°F (15.56°C), or converted to values at 60°F, by means of standard tables. These tables are not applicable to non-hydrocarbons or essentially pure hydrocarbons such as the aromatics.
Note 1-The international version of this test method is described in Test Method D-1298.
