However, this property of petroleum is an uncertain indication of its quality unless correlated with other properties. Last 1b edition approved in as D—12a.

The calculations required in 12n 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.

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. These wstm do not apply to the current calculation procedures and it is up to the user to determine whether this test method provides results of sufficient accuracy for the intended purpose.

Permission Permission rights to photocopy the standa standard rd awtm also be secure secured d from the ASTM website www. 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.

As the voice of the U. 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. Standards Subsctiption may be the perfect solution.

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. Since the same coefficients were used in compiling each set of tables, corrections made over the same temperature temper ature interv interval al minim minimize ize errors arising from possible dif differenc ferences es between betw een the coe coefffici icient ent of the mat materi erial al und under er tes testt and the sta standa ndard rd coefficients.

A number in paren parenthese thesess indicates the year of last reappr reapproval. Either comparison with a referenced temperature measurement system traceable to an international standard, or a determination of ice point, is suitable. Summa Summary ry of Test Method 4. 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.

It will return API or R. 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.

We share information about your activities on the site with our partners and Google partners: Document this value as the Meniscus correction. Ensure that the remainder remainder of the hydromet hydrometer er stem stem, whi which ch is abo above ve the liquid level, is not wetted as liquid on the stem affects the reading obtained.

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. 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.
