Assessing electrical measurement uncertainties

Measurement uncertainty, f

Uncertainty, f

Non-negative parameter that characterizes the dispersion of values attributed to a measurand, based on the information used.

NOTE 1: measurement uncertainty includes components arising from systematic effects, such as components associated with corrections and assigned values of standards, as well as definitional uncertainty. In some cases, estimated systematic effects are not corrected, but the associated uncertainty components are inserted instead.
