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 View as Grid List. This procedure is most suitable for determining the API gravity of low viscosity transparent liquids. The rack offers full view on the hydrometer. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Work Item s – proposed revisions of this standard.

The PTFE valves ensure fast drainage and cleaning of the tube. After temperature equilibrium has been reached, the hydrometer scale is read, and the temperature of the test portion is taken. 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 Please contact our sales team sales tamson.

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.

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 atsm the reference temperature by means of volume correction tables.

Go to Wish List. Density is an important quality indicator for automotive, aviation and marine fuels, where it affects storage, handling and combustion. The sample is brought to a specified f287 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. For specific warning statement, see 8. Density, relative density, or API gravity is a factor governing the quality and pricing of crude petroleum.

These tables are not applicable to nonhydrocarbons or essentially pure d278 such as the aromatics. The easy detachable leakage tray prevents that portions of the sample are spilled on the workbench.

Correlated with other properties, gravity can be used to give approximate hydrocarbon composition and heat of combustion. Remove This Item Compare. Link to Active This link will always route to the current Active version of the standard. Our special support eliminates the problem of mounting brackets or portions of a thermostatic bath blocking the view.

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. A TLC refrigerator circulates a cold flow through the double walls of the cylinders. Work Item s – proposed revisions of this standard. 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.

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. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Our system offers an interesting price advantage compared to other solutions based on a combination of a thermostatic bath and an external chiller.

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.

However, the gravity of a petroleum product is an uncertain indication of its quality. Audience Anyone who runs the D test method or who needs an understanding of the test method and how it is properly run. For specific warning statement, see 8. Additionally for both transparent and opaque fluids the readings shall be corrected for the thermal glass expansion effect before correcting to the reference temperature.

These tables are not applicable to nonhydrocarbons or essentially pure hydrocarbons such as the aromatics. The apparatus can also be used for testing the specific gravity of water and brine, according to ASTM D, test method D. The measuring set-up contains three glass cylinders with lids, a support, and a TLC circulator.
