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

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 Historical Version s – view previous versions of standard. Audience Anyone who runs the D test method or who needs an understanding of the test method and how it is properly run.

Why is the standard test method for density, relative density, or API gravity of crude petroleum and liquid petroleum products by hydrometer method important? The easy detachable leakage tray prevents that portions of the sample are spilled on the workbench.

The measuring set-up contains three glass cylinders with lids, a support, and a TLC circulator. 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.

Show 9 15 These tables are not applicable to nonhydrocarbons or essentially pure hydrocarbons such as the aromatics. 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, aastm base prover volume determination.

The rack offers full view on the hydrometer. The apparatus can also be used for testing the specific gravity of water and brine, according to ASTM D, test method D. Work Item s – proposed revisions of this standard. 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 zstm petroleum and petroleum products normally handled as liquids and having a Reid vapor pressure Test Method D of Density, relative density, or API gravity is a factor governing the quality and pricing of crude petroleum.

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.

Certificate Program This training course is part of the following certificate programs:. Correlated with other properties, gravity can be used to give approximate hydrocarbon composition and heat of combustion. Our special support eliminates the problem of mounting brackets or portions of a thermostatic bath blocking the view.

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. Density is an important quality atm for automotive, aviation and marine fuels, where it affects storage, handling and combustion.

The appropriate hydrometer and thermometer, also at a similar temperature, are lowered into the test portion and allowed to settle. View as Grid List. Additionally for both transparent and opaque fluids the readings shall be corrected for the thermal glass expansion effect before correcting to the reference temperature.

Our system offers an interesting price advantage compared to other solutions based on a combination of a thermostatic bath and an external chiller. Learning Outcomes By the end of this course you will be able to: Add to Cart Add to Cart. The sample is brought to a specified temperature placed in a constant temperature bath to avoid excessive asgm variation during the test and a test portion is transferred to a hydrometer cylinder that has been brought to approximately the same temperature.

The values given in parentheses are mathematical conversions to SI f287 that are provided for information only and are not considered standard. For specific warning statement, see 8. After temperature equilibrium has been reached, the hydrometer scale is read, and the temperature of the test portion is taken. 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.

Active view current version of standard. When used in connection with bulk oil measurements, volume correction errors are minimized by observing the hydrometer reading at a temperature close to that of the bulk oil temperature.

For specific warning statement, see 8. The PTFE valves ensure fast drainage and cleaning of the tube. 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.

A TLC refrigerator circulates a cold flow through the double walls of the cylinders. Remove This Item Compare. However, the gravity of a petroleum product is an uncertain indication of its quality. 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.
