Measurement standard (etalon): realization of the definition of a given quantity, with a stated quantity value and associated measurement uncertainty, used as a
reference.
International measurement standard: measurement standard recognized by
signatories to an international agreement and intended to be used worldwide.
National measurement standard: measurement standard recognized by national
authority to serve in a state or economy as the basis for assigning quantity values to
other measurement standards for the kind of a quantity concerned.
Primary measurement standard: measuring standard established using the primary reference measurement procedure, or created as an artifact, chosen by convention.
Secondary measurement standard: measurement standard established through
calibration with respect to a primary measurement standard for the quantity of the
same kind.
Reference measurement standard: measurement standard designed for the calibration of other measurement standards of the quantities of a given kind in a given
organization or at a given location.
Working measurement standard: measurement standard that is used routinely
to calibrate or verify measuring instruments or measuring systems.
Note 1: A working measurement standard is usually calibrated with respect to a
reference measurement standard.
Note 2: In relation to verification, the term ‘check standard’ or ‘control standard’
are also sometimes used.
There are several organization on international or regional level aiming to support the implementation of metrology system. The list of most relevant is given in
Table 3.8.
