Work Item s – proposed revisions of this standard. Values are measured c287 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.

API Specific Gravity of Petroleum Products – ASTM D287, D1298, D3142, D6822

Density, relative density, or API gravity is a factor governing the quality and v287 of crude petroleum. Work Item s – proposed revisions of this standard.

The measuring set-up contains three glass cylinders with lids, a support, and a TLC circulator. After temperature equilibrium has been reached, the hydrometer scale is read, and the temperature of the test portion is taken. Our system offers an interesting price advantage compared to other solutions based on a combination of a thermostatic bath and an external chiller.

Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: For specific warning statement, see 8. Additionally for both transparent and opaque fluids the readings shall be corrected for the thermal glass expansion effect before correcting to the reference temperature.

D27 Anyone who runs the D test method or who needs an understanding of the test method and how it is properly run. These tables are not applicable to nonhydrocarbons or essentially pure hydrocarbons such as the aromatics.

Density is an important quality indicator for automotive, aviation and marine fuels, where it affects storage, handling and combustion.

The apparatus can also be used for testing the specific gravity of water and brine, according to ASTM D, test method D. Note 1—The international version of this test method is described in Test Method. Our special support eliminates the problem of mounting brackets or portions of a thermostatic bath blocking the view.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The easy detachable leakage tray prevents that portions of the sample are spilled on the workbench. For specific warning statement, see 8. The PTFE valves ensure fast drainage and cleaning of the tube. Learning Outcomes By the end of this course you will be able to: The appropriate hydrometer and thermometer, also at a similar temperature, are lowered into the test portion and allowed to settle.

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.

API Specific Gravity of Petroleum Products – ASTM D, D, D, D | Lawler Manufacturing

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 asgm and petroleum products normally handled as liquids and having a Reid vapor pressure Test Method D of However, this property of petroleum is an uncertain indication of its quality unless correlated with other properties.

The sample is brought to a specified temperature placed in a constant temperature bath zstm 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. Show 9 15 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 rack offers full view on the hydrometer. 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. 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.
