ASTM D1217 for Density and Relative Density (Specific Gravity) of Liquids
ASTM D1217 Standard Test Method for Density and Relative Density (Specific Gravity) of Liquids by Bingham Pycnometer
1. Scope
1.1 This test method covers the measurement of the density of pure hydrocarbons or petroleum distillates boiling between 90 and 110°C that can be handled in a normal fashion as a liquid at the specified test temperatures of 20 and 25°C.
1.2 This test method provides a calculation procedure for conversion of density to relative density (specific gravity).
1.3 The values stated in SI units are to be regarded as the standard.
1.4 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. Specific precautionary statements are given in Note 1, Note 2, and Note 3.

3. Terminology
3.1 Definitions:
3.1.1 density - the weight in vacuo, (that is, the mass) of a unit volume of the material at any given temperature.
3.1.2 relative density (specific gravity) - the ratio of the mass (weight in vacuo) of a given volume of material at a temperature, t1, to the mass of an equal volume of water at a reference temperature, t2; or it is the ratio of the density of the material at t 1 to the density of water at t2. When the reference temperature is 4.00°C, the temperature at which the relative density of water is unity, relative density (specific gravity) and density are numerically equal.
