However, this property of petroleum is an uncertain indication of its quality unless correlated with other properties. Audience Anyone who runs the D test method or who needs an understanding of the test method and how it is properly run. Correlated with other properties, gravity can be used to give approximate hydrocarbon composition and heat of combustion. 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.

Please contact our sales team sales tamson. A TLC refrigerator circulates a cold flow through the double walls of the cylinders. The apparatus can also be used for testing the specific gravity of water and brine, according to ASTM D, test method D. After temperature equilibrium has been reached, the hydrometer scale is read, and the temperature of the test portion is taken.

Add to Cart Add to Cart. 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.

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: The easy detachable leakage tray prevents that portions of the sample are spilled on the workbench.

The sample is brought astmm 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.

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. 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.

Note 1—The international version of this test method is described in Test Method. Show 9 15 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.

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. Density, relative density, or API gravity is a factor governing the quality and pricing of crude petroleum. Then the calculations required in Section 9 shall be performed and documented before using the final wstm in a subsequent calculation procedure measurement ticket calculation, meter factor calculation, or base prover volume determination.

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

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 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 This procedure is most suitable for determining the API gravity of low viscosity aastm liquids.

Asrm 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. Work Item s – proposed revisions of this standard. For specific warning statement, see 8.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. This test method can also be used for viscous liquids by allowing sufficient time for the hydrometer to reach d2887 equilibrium, and for opaque liquids by employing a suitable d2877 correction.
