These values do not apply to the current calculation d11298 and it is up to the user to determine whether this test method provides results of sufficient accuracy for the intended purpose. Convert the calculated R. This procedure is most suitable for determining the density, relative density specific gravityor API gravity of low viscosity transparent liquids.

Density is an important quality indicator for automotive, aviation and marine fuels, where it affects storage, handling and combustion. Readings are measured on a hydrometer at either the reference temperature or at another convenient temperature, and readings are corrected for the meniscus effect, the thermal glass expansion effect, alternative calibration temperature effects and to the reference temperature by means of the Petroleum Measurement Tables; values obtained at other than the reference temperature being hydrometer readings and not density measurements.
Document this value as the Meniscus correction.

This procedure 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. This procedure 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.
Additionally for both transparent and opaque fluids the readings shall be corrected for the thermal glass expansion effect and alternative calibration temperature effects before correcting to the reference temperature.
