The E-Learning Center provides advanced asttm that let you set up learning plans, track learning progress and compliance, and run reports. Correlated with other properties, gravity can be used to give approximate hydrocarbon composition and heat of combustion.

Additionally for both transparent and opaque fluids the readings shall be corrected for x287 thermal glass expansion effect before correcting to the reference temperature.

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

Historical Version s – view previous versions of 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 crude petroleum and petroleum products normally handled as liquids and having a Reid vapor pressure Test Method D of Audience Anyone who runs the D test method or who needs an understanding of the test method and how it is properly run.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

These tables are not applicable to nonhydrocarbons or essentially pure hydrocarbons such as the aromatics. Our system offers an interesting price advantage compared to other solutions based on a combination of a thermostatic bath and an external chiller. For specific warning statement, see 8. Learning Outcomes By the end of this course you will be able to: Work Item s – proposed revisions of this standard. The measuring set-up contains three glass cylinders with lids, a support, and a TLC circulator.

Our special support eliminates the problem of mounting brackets or portions of a thermostatic bath blocking the view. Density is an important quality indicator for automotive, aviation and marine fuels, where it affects storage, handling and combustion. Add to Cart Add to Cart. View as Grid List.

The apparatus can also be used for testing the specific gravity of water and brine, according to ASTM D, test method D. 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 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, 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.

However, this property of petroleum is an qstm indication of its quality unless correlated with other properties.

Show 9 15 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. However, the gravity of a petroleum product is an uncertain indication of its quality. These tables are not applicable to nonhydrocarbons or essentially pure hydrocarbons such as the aromatics.

When used in connection with bulk oil measurements, volume correction errors are minimized by observing the hydrometer reading at a temperature close d2887 that of the bulk oil temperature. 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:. Then the calculations required in Section 9 shall be s287 and documented before using the final result in a sstm 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. 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, relative density, or API gravity is a factor governing the quality and pricing of crude petroleum. Values are measured on a hydrometer at either the reference temperature or d2287 another convenient temperature, and readings corrected for the meniscus effect, aastm thermal glass expansion effect, alternate calibration temperature effects and to the reference temperature by means of volume correction tables.
