    en.wikipedia.org/wiki/Calibration

    The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...

  3. Metrology - Wikipedia

    en.wikipedia.org/wiki/Metrology

    Secondary standards are calibrated with reference to a primary standard. Working standards, used to calibrate (or check) measuring instruments or other material measures, are calibrated with respect to secondary standards. The hierarchy preserves the quality of the higher standards. [20] An example of a standard would be gauge blocks for

  4. Standard (metrology) - Wikipedia

    A set of gauge blocks are used as a working standard to check the calibration of measurement tools such as micrometers.. An example of a primary standard was the international prototype of the kilogram (IPK) which was the master kilogram and the primary mass standard for the International System of Units (SI).

    Green Tea standard reference. Certified reference materials (CRMs) are 'controls' or standards used to check the quality and metrological traceability of products, to validate analytical measurement methods, or for the calibration of instruments. [1] A certified reference material is a particular form of measurement standard.

  7. Measurement microphone calibration - Wikipedia

    en.wikipedia.org/wiki/Measurement_microphone...

    Reciprocity calibration is a specialist process, and because it forms the basis of the primary standard for sound pressure, many national measurement institutes have invested significant research efforts to refine the method and develop calibration facilities. A system is also commercially available from Brüel & Kjær.
