Metrological traceability refers to the measurement result which may be related with an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is often a basic assurance that the relationship exists involving the measurement outcomes of a measurement instrument and also the value of a measurement standard. All Tektronix standards are traceable straight away to the International System of Measurements (SI), which is 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 brings about the SI makes it possible to achieve the accuracy, precision and interchangeability necessary for global trade markets. To supply truly standardized components, industry is dependent upon reliable and consistent measurements which are traceable to some recognized measurement system like the International System of Units.
Traceability is specially vital that you companies which must adhere to 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 keep to the requirements of ISO so that they can claim ISO compliance because of their product. This compliance is normally a sign of your organization’s commitment to service and/or quality.
NIST Traceable Calibration
Within the U.S., NIST is the legally established National Standards Laboratory. Consequently, NIST has the responsibility “to develop, maintain and retain custody from the national standards of measurement, and to provide you with the means and methods to create measurements in line with those standards; to make sure the compatibility of United states of america national measurement standards with those standards; and assure the compatibility of United States national measurement standards with that relating to other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations with the seven base units with the SI.
Important a NIST traceable calibration is thorough documentation from the measurement process employed to establish the compilation of calibrations that successively connect to the desired reference standard. NIST is responsible only for documenting traceability due to the reference standards and also the instruments it directly measures. Documenting NIST traceable calibrations in the commercial environment could be the sole responsibility of the lab performing the calibration work.
