Metrological traceability means measurement result which can be related through an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It can be a basic assurance a relationship exists involving the measurement connection between a measurement instrument and also the worth of a measurement standard. All of Tektronix standards are traceable right to the International System of Measurements (SI), which is the most widely used 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 can help you reach the accuracy, precision and interchangeability necessary for global trade markets. To provide truly standardized components, industry is dependent upon consistent and reliable measurements that are traceable to some recognized measurement system such as the International System of Units.
Traceability is especially imperative that you firms that must conform 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 stick to the requirements of ISO to be able to claim ISO compliance for his or her product. This compliance is commonly a signal of an organization’s dedication to service and/or quality.
NIST Traceable Calibration
Within the U.S., NIST will be the legally established National Standards Laboratory. Therefore, NIST has got the responsibility “to develop, maintain and retain custody with the national standards of measurement, also to supply the means and techniques to create measurements consistent with those standards; to assure the compatibility of United States national measurement standards with those standards; and to assure the compatibility of United states of america national measurement standards with those of 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 with the measurement process utilized to establish the compilation of calibrations that successively hyperlink to the specified reference standard. NIST is responsible only for documenting traceability for the reference standards and the instruments it directly measures. Documenting NIST traceable calibrations in the industry environment could be the sole responsibility in the lab performing the calibration work.
