    Metrological traceability means the measurement result which may be related using 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 and the value of a measurement standard. Most of Tektronix standards are traceable straight away to the International System of Measurements (SI), the 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 brings about the SI makes it possible to attain the accuracy, precision and interchangeability essential for global trade markets. To deliver truly standardized components, industry will depend on reliable and consistent measurements that are traceable to some recognized measurement system like the International System of Units.

    Traceability is very important to companies that must conform to 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 be able to claim ISO compliance for his or her product. This compliance is generally an illustration of the organization’s resolve for service and/or quality.

    NIST Traceable Calibration

    Within 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 also to give you the means and techniques to make measurements in line with those standards; to assure the compatibility of Usa national measurement standards with those standards; and to assure the compatibility of United States national measurement standards with that regarding other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations from the seven base units with the SI.

    Fundamental to a NIST traceable calibration is thorough documentation in the measurement process employed to establish the group of calibrations that successively link to the specified reference standard. NIST is responsible just for documenting traceability for its reference standards as well as the instruments it directly measures. Documenting NIST traceable calibrations available environment could be the sole responsibility from the lab performing the calibration work.
