API Specific Gravity of Petroleum Products – ASTM D287, D1298, D3142, D6822
Correlated with other properties, gravity can be used to give approximate hydrocarbon composition and heat of combustion. These tables are not applicable to nonhydrocarbons or essentially pure hydrocarbons such as the aromatics.
The easy detachable leakage tray prevents that portions of the sample are spilled on the workbench. Note 1—The international version of this test method is described in Test Method. After temperature equilibrium has been reached, the hydrometer scale is read, and the temperature of the test portion is taken. For specific warning statement, see 8.
This procedure is most suitable for determining the API gravity of low viscosity transparent liquids. Active view current version of standard. The appropriate hydrometer and thermometer, also at a similar temperature, are lowered into the test portion and allowed to settle. Then the calculations required in Section 9 shall be performed and documented before using the final result in a subsequent calculation procedure measurement ticket calculation, meter factor calculation, or base prover volume determination.
Self-guided training complete with video demonstrations, checklists, concept presentations, data sheets and glossaries Quiz with automatic grading Certificate upon successful completion of course and passing score on the quiz.
This test method can also be used for viscous liquids by allowing sufficient time for the hydrometer to reach temperature equilibrium, and for opaque liquids by employing a suitable meniscus correction. Values are measured on a hydrometer at either the reference temperature or at another convenient temperature, and readings corrected for the meniscus effect, the thermal glass expansion effect, alternate calibration temperature effects and to the reference temperature by means of volume correction tables.
For specific warning statement, see 8.
ASTM D & D & D & D & D – ASTM equipment
The sample is brought to a specified temperature placed in a constant temperature bath to avoid excessive temperature variation during the test and a test portion is transferred to a hydrometer cylinder that has been brought to approximately the same temperature. Link to Active This link will always route to the current Active version of the standard. A TLC refrigerator circulates a cold flow through the double walls of the cylinders.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and ast, not considered standard.
