API MPMS 9.1 Document Information:
Title
Manual of Petroleum Measurement Standards Chapter 9 - Density Determination Section 1 - Standard Test Method for Density, Relative Density (Specific Gravity), or API Gravity of Crude Petroleum and Liquid Petroleum Products by Hydrometer Method
American Petroleum Institute
Publication Date:
Dec 1, 2002
Scope:
This 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.
Values are measured on a hydrometer at either the reference
temperature 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.
Values determined as density, relative density, or API gravity
can be converted to equivalent values in the other units at
alternate reference temperatures by means of the Petroleum
Measurement Tables.
Annex A1 contains a procedure for verifying or certifying the
equipment for this test method.
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.
