    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 really a basic assurance that a relationship exists between your measurement connection between a measurement instrument as well as the value of a measurement standard. Most of Tektronix standards are traceable directly to the International System of Measurements (SI), the actual 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 in the SI makes it possible to get the accuracy, precision and interchangeability needed for global trade markets. To provide truly standardized components, industry is dependent upon reliable and consistent measurements that are traceable with a recognized measurement system like the International System of Units.

    Traceability is particularly important to companies that must abide by 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 continue with the requirements of ISO to be able to claim ISO compliance for his or her product. This compliance is normally a signal of the organization’s resolve for service and/or quality.

    NIST Traceable Calibration

    In the U.S., NIST is the legally established National Standards Laboratory. Therefore, NIST has the responsibility “to develop, maintain and retain custody of the national standards of measurement, and also to provide the means and techniques for making measurements consistent with those standards; to assure the compatibility of U . s . national measurement standards with those standards; also to assure the compatibility of U . s . national measurement standards with the ones from other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations with the seven base units in the SI.

    Important a NIST traceable calibration is thorough documentation from the measurement process accustomed to establish the compilation of calibrations that successively url to the desired reference standard. NIST is responsible simply for documenting traceability due to the reference standards and also the instruments it directly measures. Documenting NIST traceable calibrations available environment could be the sole responsibility of the lab performing the calibration work.
