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

    How Traceability Impacts Global Markets

    Traceability of measurement results to the SI can help you reach the accuracy, precision and interchangeability necessary for global trade markets. To provide truly standardized components, industry is determined by consistent and reliable measurements which can be traceable into a recognized measurement system for example the International System of Units.

    Traceability is particularly vital that you companies that must conform to or follow 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 keep to the requirements of ISO so that they can claim ISO compliance for product. This compliance is generally a sign of the organization’s persistence for service and/or quality.

    NIST Traceable Calibration

    From the U.S., NIST is the legally established National Standards Laboratory. Therefore, NIST contains the responsibility “to develop, maintain and retain custody from the national standards of measurement, and provide you with the means and techniques to create measurements in line with those standards; to make sure the compatibility of United states of america 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 from the seven base units in the SI.

    Fundamental to a NIST traceable calibration is thorough documentation of the measurement process accustomed to establish the compilation of calibrations that successively connect to the required reference standard. NIST is responsible limited to documenting traceability for its reference standards as well as the instruments it directly measures. Documenting NIST traceable calibrations in the industry environment may be the sole responsibility from the lab performing the calibration work.
