Correlated with other properties, gravity can be used to give approximate hydrocarbon composition and heat of combustion.

The appropriate hydrometer and thermometer, also at a similar temperature, are lowered into the test portion and allowed to settle.

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 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 measuring set-up contains three glass cylinders with lids, a support, and a TLC circulator.

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. 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.

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

About satm 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.

However, the gravity of a petroleum product is an uncertain indication of its quality. A TLC refrigerator circulates a cold flow through the double walls of the cylinders. Why is the standard test method for density, relative density, or API gravity of crude petroleum and liquid petroleum products by hydrometer method important?

This test method can also be used for viscous liquids by allowing sufficient time for the aatm to reach temperature equilibrium, and for opaque liquids by employing a suitable meniscus correction.
