Density is an important quality indicator for automotive, aviation and marine fuels, where it affects storage, handling and combustion. Go to Wish List.
Why is the standard test method for density, relative density, or API gravity of crude petroleum and liquid petroleum products by hydrometer method important? The E-Learning Center provides advanced features that let you set up learning plans, track asfm progress and compliance, and run reports. Work Item s – proposed revisions of this standard. However, the gravity of a petroleum product is an uncertain indication of its quality.
Additionally for both transparent and opaque fluids the readings shall be corrected for the asttm glass expansion effect before correcting to the reference temperature. The observed hydrometer reading is corrected aatm 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 However, this property of petroleum is an uncertain indication of its quality unless correlated with other properties.
Certificate Program This training course is part of the following certificate programs:.
The appropriate hydrometer and thermometer, also at a similar temperature, are lowered into the test portion and allowed to settle. 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 to that of the bulk oil temperature. The apparatus can also be used for testing the specific gravity of water and brine, according to ASTM D, test astk D.
Learning Outcomes By the end of this course you will be able to: 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.

Historical Version s – view previous versions of standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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. Density, relative density, or API gravity is a factor governing the quality and pricing of crude petroleum. Link to Active This link will always route to the current Active version of the standard.

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 astk is transferred to a hydrometer cylinder that has been brought to approximately the same temperature.
