Reference measurement procedure used to obtain a measurement result without relation to a
measurement standard for a quantity of the same kind.
Example The volume of water delivered by a 50 ml pipette at 20 °C is measured by weighing the
water delivered by the pipette into a beaker, taking the mass of beaker plus water minus the mass of
the initially empty beaker, and correcting the mass difference for the actual water temperature
using the volumic mass (mass density).
