Density of LPG
and of Light Hydrocarbons

ASTM D1657
IP 235
ISO 3993

ASTM D1657 - Density or Relative Density of Light Hydrocarbons
by Pressure Hydrometer.
This test method covers the determination of the density or relative density of light hydrocarbons including liquefied petroleum gases (LPG) having Reid vapour pressures exceeding 101.325 kPa (14.696 psi).

IP 235 - ISO 3993 - Density or Relative Density of LPG and of Light Hydrocarbons by Pressure Hydrometer.
The prescribed apparatus shall not be used for materials having gauge vapour pressures higher than 1,4 MPa (absolute vapour pressure 1,5 MPa) at the test temperature.
