Designation: D 1298 – 99 (Reapproved 2005)
An American National Standard
Designation: Manual of Petroleum Measurement Standards (MPMS), Chapter 9.1 Designation: 160/99
Standard Test Method for
Density, Relative Density (Specific Gravity), or API Gravity of Crude Petroleum and Liquid Petroleum Products by Hydrometer Method1
This standard is issued under the fixed designation D 1298; thenumber 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 standard has been approved for use by agencies of the Department of Defense.
1. Scope 1.1This test 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 nonpetroleum products normally handled as liquids, and having a Reid vapor pressure of 101.325 kPa (14.696 psi) or less. 1.2 Values are measured on a hydrometer at either the referencetemperature or at another convenient temperature, and readings corrected to the reference temperature by means of the Petroleum Measurement Tables; values obtained at other than the reference temperature being hydrometer readings and not density measurements. 1.3 Values determined as density, relative density, or API gravity can be converted to equivalent values in the other units at alternatereference temperatures by means of the Petroleum Measurement Tables. 1.4 Annex A1 contains a procedure for verifying or certifying the equipment for this test method. 1.5 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 theapplicability of regulatory limitations prior to use.
1 This test method is under the jurisdiction of ASTM Committee D02 on Petroleum Products and Lubricants and the API Committee on Petroleum Measurement, and is the direct responsibility of D02.02 /COMQ, the joint ASTM-API Committee on Static Petroleum Measurement. Current edition approved Nov. 1, 2005. Published December 2005. Originally approved in1953. Last previous edition approved in 1999 as D 1298–99e2.
