measurement procedure accepted as providing measurement results fit for their intended use in assessing measurement trueness of measured quantity values obtained from other measurement procedures for quantities of the same kind, in calibration, or in characterizing reference materials
ANNOTATION (informative) [5 June 2014] The definition systematically uses preferred terms and so is long and complex. A shorter definition, coupled with a Note, might be sufficient:
"measurement procedure used in the process of providing results for assessing trueness of values obtained from other measurement procedures for quantities of the same kind"
NOTE 1 Reference measurement procedures are often used in calibration and in assigning values to reference materials.
