Our system offers an interesting price advantage compared to other solutions based on a combination of a thermostatic bath and an external chiller. Note 1—The international version of this test method is described in Test Method.

For specific warning statement, see 8. The E-Learning Center provides advanced features that let you set up learning plans, track learning progress and compliance, and run reports.

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.

For specific warning statement, see 8. Link to Active This link will always route to the current Active version of the standard. A TLC refrigerator circulates a cold flow through the ashm walls of the cylinders.

The sample is brought to 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.

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, or base prover volume determination.

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 appropriate hydrometer and thermometer, also at a similar temperature, are lowered into the test portion and allowed to settle. JavaScript seems to be disabled in your browser.

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

After temperature equilibrium has been reached, the hydrometer scale is read, and the temperature of the test portion xstm 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.

Values are measured on a hydrometer at either the reference temperature or at aztm 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 asfm determine the applicability of regulatory limitations prior to use.

Correlated with other properties, gravity can be used to give approximate hydrocarbon composition and heat of combustion. Work Item s – proposed revisions of this standard.

The apparatus can also be used for testing the specific gravity of water and brine, according to ASTM D, test method D. Add to Cart Add to Cart. When used in connection with bulk oil measurements, volume correction errors are minimized by observing the hydrometer reading astn a temperature close to that of the bulk oil temperature.

The asym given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Density, relative density, or API gravity is a factor governing the quality and pricing of crude petroleum. Why is the standard test method for density, relative density, or API gravity of crude petroleum and liquid petroleum products by hydrometer method important? 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.

Additionally for both transparent and opaque fluids the readings shall be corrected for the thermal glass expansion effect before correcting to the reference temperature. Preview a Course Click here to preview a sample course.

Audience Anyone who runs the D test method or who needs an understanding of the test method and how it is properly run. Values are measured on a hydrometer at either the reference temperature or at another convenient temperature, and readings corrected for the meniscus effect, aztm thermal glass expansion effect, alternate calibration temperature effects and to the reference temperature by means of volume correction tables.

The PTFE valves ensure fast drainage and cleaning of the tube. Density is an important quality indicator for automotive, aviation and marine fuels, where it affects storage, handling and combustion.
