CONTAINED IN VOL. 05.05, 2018 Defines procedures for the calibration of U-tube density cells.

1.1This practice outlines procedures for the calibration of U-tube density cells. It is applicable to instruments capable of determining fluid density at temperatures in the range –10 °C to 200 °C and pressures from just greater than the saturation pressure to 140 MPa. The practice refers to density cells as they are utilized to make measurements of fluids primarily in the compressed-liquid state. Examples of substances for which the density can be determined with a calibrated U-tube density meter include: crude oils, gasoline and gasoline-oxygenate blends, diesel and jet fuels, hydraulic fluids, and lubricating oils.

1.2This practice specifies a procedure for the determination of the expanded uncertainty of the density measurement.

1.3This practice pertains to fluids with viscosities < 1 Pa·s (1000 centipoise) at ambient conditions.

1.44 The values listed in SI units are regarded as the standard, unless otherwise stated. The SI unit for mass density is kilograms per cubic metre (kg·m^-3) and can be given as grams per cubic centimetre (g·cm^-3).

1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
