Measurement standard, maintenance Set of operations necessary to preserve the metrological characteristics of a measurement standard within appropriate limits. |
Measurement standard, national Standard recognised by a national decision to serve in a country as the basis for assigning values to other standards of the quantity concerned. |
Measurement Uncertainty"A parameter associated with the result of a measurement, that characterizes the dispersion of the values that could reasonably be attributed to the measurand." |
Measurement unit See Unit of measurement. A particular quantity, defined and adopted by convention, with which other quantities of the same kind are compared in order to express their magnitudes relative to that quantity. |
Measuring chain Series of elements of a measuring instrument or measuring system that constitutes the path of the measurement signal from the input to the output. |

Measuring error, absolute When it is necessary to distinguish “error” from “relative error” the former is sometimes called “absolute error of measurement”. |
Measuring instrument Device intended to be used to make measurements, alone or in conjunction with supplementary devices. |
Measuring range Set of values of measurands for which the error of a measuring instrument is intended to lie within specified limits. |
