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

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 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.
This procedure is most suitable for determining the API gravity of low viscosity transparent liquids. Show 9 15 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.

However, the gravity of a petroleum product is an uncertain indication of its quality. About the Course This course covers the determination by dd287 of a glass hydrometer in conjunction with a series of calculations of the API asgm of crude petroleum and petroleum products normally handled as liquids and having a Reid vapor pressure Test Method D of 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.

The appropriate hydrometer and thermometer, also at a similar temperature, are lowered into the test portion and allowed to settle. For specific warning statement, see 8.
Why is the standard test method for density, relative density, or API gravity of crude petroleum and liquid petroleum products by hydrometer method important? Work Item s – proposed revisions of this standard. Preview a Course Click here to preview a sample course.
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 E-Learning Center provides advanced axtm that let you set up learning plans, track learning progress and compliance, and run reports. For specific warning statement, d87 8. These tables are not applicable to nonhydrocarbons or essentially pure hydrocarbons awtm as the aromatics.
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.
