It is up to the user to determine whether this test method provides results of sufficient accuracy for the intended purpose. These values 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.

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.

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.

The precision of WAT for crude petroleum using this technique has not been determined.
