    Metrological traceability means the measurement result that may be related through an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is a basic assurance that the relationship exists between your measurement outcomes of a measurement instrument and the value of a measurement standard. All of Tektronix standards are traceable straight away to the International System of Measurements (SI), which is most favored international system of measurement to blame for defining the meter, kilogram, second, ampere, kelvin, mole, and candela.

    How Traceability Impacts Global Markets

    Traceability of measurement results to the SI assists you to attain the accuracy, precision and interchangeability required for global trade markets. To deliver truly standardized components, industry is dependent upon reliable and consistent measurements which are traceable into a recognized measurement system such as the International System of Units.

    Traceability is especially crucial that you companies which must comply with or stick to the requirements of International Organization for Standardization (ISO) standard(s). ISO requirements often require that test, measurement and control equipment be traceable to recognized national or international standards. Other organizations may voluntarily follow the requirements of ISO to enable them to claim ISO compliance because of their product. This compliance is usually an indication of an organization’s dedication to service and/or quality.

    NIST Traceable Calibration

    Within the U.S., NIST could be the legally established National Standards Laboratory. Consequently, NIST has got the responsibility “to develop, maintain and retain custody from the national standards of measurement, and to supply the means and techniques in making measurements consistent with those standards; to guarantee the compatibility of U . s . national measurement standards with those standards; and also to assure the compatibility of United states of america national measurement standards with that regarding other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations in the seven base units of the SI.

    Fundamental to a NIST traceable calibration is thorough documentation with the measurement process accustomed to establish the series of calibrations that successively link to the actual required reference standard. NIST is responsible only for documenting traceability for the reference standards and the instruments it directly measures. Documenting NIST traceable calibrations in the commercial environment is the sole responsibility from the lab performing the calibration work.
