Metrological traceability refers back to the measurement result which is often related with an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is a basic assurance that a relationship exists involving the measurement connection between a measurement instrument along with the price of a measurement standard. Every one of Tektronix standards are traceable right to the International System of Measurements (SI), the actual most widely used international system of measurement in charge of 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 achieve the accuracy, precision and interchangeability essential for global trade markets. To offer truly standardized components, industry will depend on consistent and reliable measurements that are traceable into a recognized measurement system including the International System of Units.
Traceability is especially crucial that you firms that must comply with 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 in order to claim ISO compliance for product. This compliance is normally a sign of an organization’s dedication to service and/or quality.
NIST Traceable Calibration
Within the U.S., NIST may be the legally established National Standards Laboratory. Therefore, NIST has the responsibility “to develop, maintain and retain custody in the national standards of measurement, also to provide the means and techniques to make measurements in line with those standards; to guarantee the compatibility of Usa national measurement standards with those standards; and assure the compatibility of United States national measurement standards with the ones from 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 of the measurement process accustomed to establish the series of calibrations that successively hyperlink to the actual required reference standard. NIST is responsible limited to documenting traceability due to the reference standards and also the instruments it directly measures. Documenting NIST traceable calibrations in the industry environment may be the sole responsibility of the lab performing the calibration work.
