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 vapor pressures exceeding 101.325 kPa (14.696 psi).
IP 235 ISO 3993 DETERMINATION OF DENSITY OF LIGHT HYDROCARBONS – PRESSURE HYDROMETER METHOD
This method provides a procedure for determining the density of light hydrocarbons including liquefied petroleum gases. The prescribed apparatus should not be used for materials having vapour pressures higher than 14 bar at the test temperature.
