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. Historical Version s – view previous versions of standard. A TLC refrigerator circulates a cold flow through the double walls of the cylinders. Learning Outcomes By the end of this course you will be asgm to: Go to Wish List.

These tables are not applicable to nonhydrocarbons or essentially pure hydrocarbons such as the aromatics. Correlated with other properties, gravity can be used to give approximate hydrocarbon composition and heat of combustion. Density is an important quality indicator for automotive, aviation and marine fuels, where it affects storage, handling and combustion.

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 v287. Why should you use a Tamson asym by hydrometer set-up? 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 sample is brought to wstm specified temperature placed atm 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. The easy detachable leakage tray prevents that portions of the sample are spilled on the workbench. After temperature equilibrium has been reached, the hydrometer scale is read, and the temperature of the test portion is taken.

Work Item s – proposed revisions of this standard. 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. 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.

Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: This procedure is most suitable for determining the API gravity of low viscosity transparent liquids.

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.

Show 9 15 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 Active view current version of standard.

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

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. View as Grid List. 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. These tables are not applicable to nonhydrocarbons or essentially pure hydrocarbons such as the aromatics.

Additionally for both transparent and opaque fluids the readings shall be corrected for the thermal glass expansion effect before correcting to the reference temperature. However, the gravity of a petroleum product is an uncertain indication of its quality. The PTFE valves ensure fast drainage and cleaning of the tube. The rack offers full view on the hydrometer.

Work Item wstm – proposed revisions of this standard. 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. Why is the standard test method for density, relative density, or API gravity of crude petroleum and liquid petroleum products by hydrometer method important?

Density, relative density, or API gravity is a factor governing the quality aastm pricing of crude petroleum. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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.
