Metrological traceability refers back to the measurement result which may be related via an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is a basic assurance a relationship exists between the measurement link between a measurement instrument along with the worth of a measurement standard. All of Tektronix standards are traceable directly to the International System of Measurements (SI), which is most in-demand 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 to the SI makes it possible to get the accuracy, precision and interchangeability essential for global trade markets. To provide truly standardized components, industry depends upon reliable and consistent measurements which are traceable with a recognized measurement system for example the International System of Units.
Traceability is particularly vital that you businesses 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 stick to the requirements of ISO to enable them to claim ISO compliance for their product. This compliance is usually an indication associated with an organization’s persistence for service and/or quality.
NIST Traceable Calibration
In the U.S., NIST will be the legally established National Standards Laboratory. Therefore, NIST contains the responsibility “to develop, maintain and retain custody in the national standards of measurement, also to supply the means and techniques in making measurements consistent with those standards; in order to guarantee the compatibility of Usa national measurement standards with those standards; and assure the compatibility of Usa 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 of the SI.
Fundamental to a NIST traceable calibration is thorough documentation in the measurement process utilized to establish the group of calibrations that successively hyperlink to the desired 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 in the industry environment may be the sole responsibility of the lab performing the calibration work.
