Metrological traceability refers to the measurement result which can be related using an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It can be a basic assurance which a relationship exists between your measurement connection between a measurement instrument and also the valuation on a measurement standard. Most of Tektronix standards are traceable straight to the International System of Measurements (SI), the most favored international system of measurement responsible 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 achieve the accuracy, precision and interchangeability required for global trade markets. To deliver truly standardized components, industry will depend on reliable and consistent measurements which can be traceable with a recognized measurement system for example the International System of Units.
Traceability is especially crucial that you companies that must adhere to 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 so that they can claim ISO compliance for his or her product. This compliance is generally a sign of the 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 gets the responsibility “to develop, maintain and retain custody of the national standards of measurement, also to supply the means and techniques to make measurements consistent with those standards; to make sure the compatibility of United States 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 in the seven base units with the SI.
Important a NIST traceable calibration is thorough documentation from the measurement process used to establish the group of calibrations that successively hyperlink to the actual required 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 in the industry environment will be the sole responsibility of the lab performing the calibration work.
