ASTM D 1298-12b API

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. ASTM D bnm. The calculations required in Section 10 shall be applied to the initial hydrometer reading with observations and results reported as required by Section 11 prior to use in a subsequent calculation procedure ticket calculation, meter factor calculation, or base prover volume determination.

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, alternate 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.

Either comparison with a referenced temperature measurement system traceable to an international standard, or a d2198 of ice point, is suitable.

It is up to the user to determine whether this test method provides results of sufficient accuracy for the intended purpose. This procedure is most suitable for determining the density, relative density specific gravityor API gravity of low viscosity transparent liquids.
