TestProcess.Measure.Density.Mass.Liquid

Test Process that measures a liquid’s density as defined by the amount of mass present in a specified volume of liquid at a given temperature. Temperature affects density, as does the pressure to the extent that the liquid compresses. In, liquids deemed sufficiently incompressible, the volume does not depend on pressure.

 ** Includes non-uniformity and voids (if any) 

Required Parameters

  • Density {kg·m3, g·cm3, lb·ft3}
  • Temperature

Optional Parameters

  • Pressure
  • Volume

Measured Value & Uncertainty

  • Density {kg·m3, g·cm3, lb·ft3}

TestProcess.Measure.Density.Mass.Gas

Test Process that measures a gas’s density as defined by the amount of mass present in a specified volume of gas at a given temperature and pressure. 

Gases are extremely responsive to temperature and pressure, causing their densities to change rather quickly.  Measuring the density of gas the Ideal Gas Law (P*V = nRT) must be taken into account.

 ** Includes non-uniformity

Required Parameters

  • Density {kg·m3, g·cm3, lb·ft3}
  • Pressure
  • Temperature

Optional Parameters

  • Volume

Measured Value & Uncertainty

  • Density {kg·m3, g·cm3, lb·ft3}

TestProcess.Measure.Resistance.Insulation
