However, the gravity of a petroleum product is an uncertain indication of its quality. Correlated with other properties, gravity can be used to give approximate hydrocarbon composition and heat of combustion.

Audience Anyone who ashm the D test method or who needs an understanding of the test method and how it is properly run. Work Item s – proposed revisions of this standard.

API Specific Gravity of Petroleum Products – ASTM D287, D1298, D3142, D6822

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. The appropriate hydrometer and thermometer, also at a similar temperature, are lowered into the test portion and allowed to settle. Recall the apparatus requirements for the determination of API gravity of crude petroleum and petroleum products Recall the procedural steps for the determination of API gravity of crude petroleum and petroleum products Describe the steps required for the calculation process Describe the reporting requirements ashm API gravity.

Why should you use a Tamson density by hydrometer set-up? When used in connection with bulk oil measurements, volume correction errors are minimized by d2887 the hydrometer asrm at a temperature close to that of the bulk oil temperature.

Density, relative density, or API gravity is a factor governing the quality and pricing of crude petroleum. However, this property of petroleum is an uncertain indication of its quality 2d87 correlated with other properties. The PTFE valves ensure fast drainage and cleaning of the tube. 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. Density is an important quality indicator for automotive, aviation and marine fuels, where it affects storage, handling and combustion.

The observed hydrometer reading is corrected for the meniscus effect, the thermal glass expansion effect, alternate calibration temperature effects and then reduced to the reference temperature by means of the volume correction factors or tables as applicable by use of the appropriate adjunct to ASTM D guide for petroleum measurement tables API MPMS Chapter After temperature equilibrium has been reached, the hydrometer scale is read, and the temperature of the test portion is taken.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The measuring set-up contains three glass cylinders with lids, a support, and a TLC circulator. Our special support eliminates the problem of mounting brackets or portions of a thermostatic bath blocking the view. For specific r287 statement, see 8. About the Course This course covers the determination by means of a glass hydrometer in conjunction with a series of calculations of the API gravity of crude petroleum and petroleum products normally handled as liquids and having a Reid vapor pressure Test Method D of For adtm warning statement, see 8.

Recall the apparatus requirements for the determination of API gravity of crude petroleum and petroleum products Recall the procedural steps for the determination of API gravity of crude petroleum and petroleum products Describe the steps required for the calculation process Describe the reporting requirements for API gravity Audience Anyone who runs the D test method or who needs an understanding of the test method and how it is properly run.

Then the calculations required in Section 9 shall be performed and documented astn using the final result in a subsequent calculation procedure measurement ticket calculation, meter factor calculation, or base prover volume determination. The rack offers full view on the hydrometer. 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.
