However, this property of petroleum is an uncertain indication of its quality unless correlated with other properties.

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.

Either comparison with a referenced temperature measurement system traceable to an international standard, or a determination of ice point, is suitable. 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. If the men meniscu iscuss cha change nges, s, clea clean n the hyd hydrom rometer eter stem and repeat until the meniscus shape remains constant.

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.

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

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.
