Copyright ASTM An American National Standard Standard Test Method for API Gravity of Crude Petroleum and Petroleum Products Hydrometer Method 1 This standard is issued under the fixed ds ii r atic n D 287 the number immediately following the designation indicates the year of original adoption or in the case of revision the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This test method has been adopted for use by government agencies to replace Method 401 of Federal Test Method Standard No. 791b. 1. Scope 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 nonhydrocarbons or essentially pure hydrocarbons such as the aromatics. Note 1 The inSe tatlonal version fl this krst method is deseribed in Test Method D 1298. 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 concerns 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.
