Standard Test Method for API Gravity of Crude Petroleum and Petroleum Products (Hydrometer Method)
|Publication Date:||10 April 2000|
|ICS Code (Petroleum products in general):||75.080|
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 D323) 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 nonhydrocarbons or essentially pure hydrocarbons such as the aromatics.
Note 1-The international version of this test method is described in Test Method D1298.
1.2 Values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.> For specific hazard statements, see Notes 3 and 4.
