Metrological traceability refers to the measurement result which can be related via an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is often a basic assurance that a relationship exists between the measurement link between a measurement instrument and also the price of a measurement standard. Most of Tektronix standards are traceable straight away to the International System of Measurements (SI), the actual 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 supply truly standardized components, industry is dependent upon reliable and consistent measurements which can be traceable into a recognized measurement system like the International System of Units.
Traceability is specially vital that you companies that must abide by 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 continue with the requirements of ISO in order to claim ISO compliance for their product. This compliance is generally a sign of an organization’s dedication to service and/or quality.
NIST Traceable Calibration
From the U.S., NIST may be the legally established National Standards Laboratory. As such, NIST has the responsibility “to develop, maintain and retain custody with the national standards of measurement, and supply the means and techniques to make measurements in step with those standards; in order to guarantee the compatibility of U . s . national measurement standards with those standards; and assure the compatibility of U . s . national measurement standards with that relating to other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations from the seven base units with the SI.
Fundamental to a NIST traceable calibration is thorough documentation in the measurement process employed to establish the series of calibrations that successively hyperlink to the specified reference standard. NIST is responsible limited to documenting traceability for the reference standards as well as the instruments it directly measures. Documenting NIST traceable calibrations available environment may be the sole responsibility of the lab performing the calibration work.
