ASTM-D1657 › Historical Revision Information
Standard Test Method for Density or Relative Density of Light Hydrocarbons by Pressure Hydrometer
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of the density or relative density of light hydrocarbons including liquefied petroleum gases (LPG) having Reid vapor pressures exceeding 101.325 kPa (14.696 psi).
1.2 The prescribed apparatus should not be used for materials having vapor pressures higher than 1.4 MPa (200 psi) at the test temperature. This pressure limit is dictated by the type of equipment. Higher pressures may apply to other equipment designs.
1.3 The values in SI units are to be regarded as the standard. The values in parentheses are for information only. Both SI and customary units have been rounded so that they may not be exactly equivalent.
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.
Significance and Use
The density or relative density of light hydrocarbons and liquefied petroleum gases is used in custody transfer quantity calculations or to satisfy transportation, storage, and regulatory requirements.
