    Metrological traceability refers back to the measurement result which is often related via an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is often a basic assurance a relationship exists involving the measurement link between a measurement instrument along with the value of a measurement standard. All of Tektronix standards are traceable directly to the International System of Measurements (SI), the actual most widely used international system of measurement in charge of defining the meter, kilogram, second, ampere, kelvin, mole, and candela.

    How Traceability Impacts Global Markets

    Traceability of measurement results to the SI enables us to get the accuracy, precision and interchangeability required for global trade markets. To supply truly standardized components, industry is determined by reliable and consistent measurements which are traceable into a recognized measurement system for example the International System of Units.

    Traceability is particularly imperative that you firms that must abide by or continue with 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 continue with the requirements of ISO to enable them to claim ISO compliance for their product. This compliance is normally a signal of your organization’s dedication to service and/or quality.

    NIST Traceable Calibration

    In the U.S., NIST could be the legally established National Standards Laboratory. Therefore, NIST has the responsibility “to develop, maintain and retain custody from the national standards of measurement, and also to give you the means and methods for making measurements in line with those standards; to assure the compatibility of United States national measurement standards with those standards; also to assure the compatibility of United States national measurement standards with those of other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations with the seven base units from the SI.

    Fundamental to a NIST traceable calibration is thorough documentation of the measurement process used to establish the number of calibrations that successively url to the actual required reference standard. NIST is responsible limited to documenting traceability for the reference standards along with the instruments it directly measures. Documenting NIST traceable calibrations in the commercial environment will be the sole responsibility with the lab performing the calibration work.
