    Metrological traceability refers back to the measurement result which may be related through an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It can be a basic assurance that the relationship exists between your measurement link between a measurement instrument as well as the worth 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 responsible for defining the meter, kilogram, second, ampere, kelvin, mole, and candela.

    How Traceability Impacts Global Markets

    Traceability of measurement leads to the SI can help you get the accuracy, precision and interchangeability required for global trade markets. To offer truly standardized components, industry depends upon consistent and reliable measurements which are traceable to a recognized measurement system such as the International System of Units.

    Traceability is specially important to firms that 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 keep to the requirements of ISO to be able to claim ISO compliance for product. This compliance is commonly 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 with the national standards of measurement, also to provide the means and methods to create measurements in keeping with those standards; in order to guarantee the compatibility of Usa national measurement standards with those standards; and 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 in the seven base units in the SI.

    Fundamental to a NIST traceable calibration is thorough documentation in the measurement process employed to establish the group of calibrations that successively url to the actual required reference standard. NIST is responsible limited to documenting traceability because of its reference standards as well as the instruments it directly measures. Documenting NIST traceable calibrations in the commercial environment may be the sole responsibility with the lab performing the calibration work.
