    Metrological traceability refers to the measurement result which can be related through an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is often a basic assurance that the relationship exists involving the measurement outcomes of a measurement instrument as well as the value of a measurement standard. All of Tektronix standards are traceable straight to the International System of Measurements (SI), the hottest international system of measurement responsible 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 supply truly standardized components, industry will depend on consistent and reliable measurements that are traceable with a recognized measurement system including the International System of Units.

    Traceability is very important to firms that must comply with or keep 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 follow the requirements of ISO to enable them to claim ISO compliance for his or her product. This compliance is generally an illustration of an organization’s commitment to service and/or quality.

    NIST Traceable Calibration

    Within the U.S., NIST is the legally established National Standards Laboratory. Consequently, NIST contains the responsibility “to develop, maintain and retain custody of the national standards of measurement, and also to provide you with the means and techniques to make measurements in keeping with those standards; to guarantee the compatibility of U . s . national measurement standards with those standards; also to assure the compatibility of United states of america 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 in the SI.

    Fundamental to a NIST traceable calibration is thorough documentation from the measurement process utilized to establish the number of calibrations that successively url to the actual required reference standard. NIST is responsible simply for documenting traceability due to the reference standards as well as the instruments it directly measures. Documenting NIST traceable calibrations available environment is the sole responsibility of the lab performing the calibration work.
