Metrological traceability means the measurement result which is often related via an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is a basic assurance that a relationship exists involving the measurement results of a measurement instrument and the worth of a measurement standard. Most of Tektronix standards are traceable straight away to the International System of Measurements (SI), which is 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 to the SI makes it possible to get the accuracy, precision and interchangeability necessary for global trade markets. To offer truly standardized components, industry is dependent upon consistent and reliable measurements which can be traceable with a recognized measurement system including the International System of Units.
Traceability is particularly 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 to enable them to claim ISO compliance for product. This compliance is normally an illustration of an organization’s resolve for service and/or quality.
NIST Traceable Calibration
Within the U.S., NIST is the legally established National Standards Laboratory. As a result, NIST has got the responsibility “to develop, maintain and retain custody of the national standards of measurement, and also to provide the means and methods to make measurements in keeping with those standards; to assure the compatibility of U . s . national measurement standards with those standards; and 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 in the SI.
Important a NIST traceable calibration is thorough documentation in the measurement process accustomed to establish the number of calibrations that successively link to the required reference standard. NIST is responsible simply for documenting traceability because of its reference standards and also the instruments it directly measures. Documenting NIST traceable calibrations available environment will be the sole responsibility with the lab performing the calibration work.
