    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 really a basic assurance that the relationship exists between your measurement results of a measurement instrument as well as the value of a measurement standard. All of Tektronix standards are traceable directly 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 brings about the SI can help you get the accuracy, precision and interchangeability needed for global trade markets. To provide truly standardized components, industry depends upon reliable and consistent measurements that are traceable into a recognized measurement system for example the International System of Units.

    Traceability is especially important to companies 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 generally a sign of an organization’s persistence for service and/or quality.

    NIST Traceable Calibration

    In the U.S., NIST is the legally established National Standards Laboratory. As such, NIST has the responsibility “to develop, maintain and retain custody in the national standards of measurement, and give you the means and techniques in making measurements in step with those standards; in order to guarantee the compatibility of United states of america national measurement standards with those standards; and assure the compatibility of United states of america national measurement standards with that relating to other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations of the seven base units in the SI.

    Fundamental to a NIST traceable calibration is thorough documentation with the measurement process accustomed to establish the number of calibrations that successively connect to the specified 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 industry environment could be the sole responsibility with the lab performing the calibration work.
