Audience Anyone who runs the D test method or who needs an understanding of the test method and how it is properly run. When used in connection with bulk oil measurements, d2887 correction errors are minimized by observing the hydrometer reading at a temperature close to that of the bulk oil temperature. 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.

Then the calculations required in Section 9 shall be performed and documented before using the final result in a subsequent calculation procedure measurement f287 calculation, meter factor calculation, or base prover d2887 determination.

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

Why is the standard test method for density, relative asym, or API gravity of crude petroleum and liquid petroleum products by hydrometer method important?

A TLC refrigerator circulates a cold flow through the double walls of the cylinders. The easy detachable leakage tray prevents that portions of the sample are spilled on the workbench. For specific warning statement, see 8. Add to Cart Add to Cart.

For specific warning statement, see 8. 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 r287 Describe the steps required for the calculation process Describe the reporting requirements for API gravity.

After temperature equilibrium has been reached, the hydrometer scale is read, and the temperature of the test portion is taken. Active view current version of standard. The rack offers full view on the hydrometer. The values given in parentheses are d278 conversions to SI units that are provided for information atsm and are not considered standard.

Learning Outcomes By the end of this course you will be able to: Please contact our sales team sales tamson. View as Grid List. 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 asym and to the reference temperature by means of volume correction tables.

Work Item s – proposed revisions of this standard. Additionally for both transparent and opaque fluids the readings shall be corrected for the thermal glass expansion effect before correcting to the reference temperature. However, the gravity of a petroleum product is an uncertain indication of its quality. Correlated with other properties, gravity can be used to give approximate hydrocarbon composition and heat of combustion.

Why should you use a Tamson density by hydrometer set-up? These tables are not applicable to nonhydrocarbons or essentially pure hydrocarbons such as the aromatics. Historical Version s – view previous versions of standard. 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.
