Metrological traceability refers back to the measurement result which can be related using an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is often a basic assurance that the relationship exists between the measurement link between a measurement instrument and the valuation on a measurement standard. Most of Tektronix standards are traceable directly to the International System of Measurements (SI), the most widely used international system of measurement accountable 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 achieve the accuracy, precision and interchangeability needed for global trade markets. To provide truly standardized components, industry will depend on reliable and consistent measurements that are traceable to a recognized measurement system including the International System of Units.
Traceability is particularly important to businesses that must conform to or follow 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 keep to the requirements of ISO so that they can claim ISO compliance for product. This compliance is commonly a sign associated with an organization’s commitment to service and/or quality.
NIST Traceable Calibration
In the U.S., NIST may be the legally established National Standards Laboratory. Therefore, NIST has the responsibility “to develop, maintain and retain custody with the national standards of measurement, and provide the means and methods in making measurements consistent with those standards; to assure the compatibility of United States national measurement standards with those standards; and also to assure the compatibility of Usa 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 of the SI.
Important a NIST traceable calibration is thorough documentation in the measurement process accustomed to establish the group of calibrations that successively link to the actual required reference standard. NIST is responsible just for documenting traceability due to the reference standards and the instruments it directly measures. Documenting NIST traceable calibrations in the commercial environment is the sole responsibility of the lab performing the calibration work.
