Metrological traceability means measurement result which may be related via an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is often a basic assurance a relationship exists relating to the measurement results of a measurement instrument as well as the worth of a measurement standard. All Tektronix standards are traceable straight away to the International System of Measurements (SI), the actual most in-demand international system of measurement to blame 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 reach the accuracy, precision and interchangeability essential for global trade markets. To offer truly standardized components, industry is determined by consistent and reliable measurements which are traceable with a recognized measurement system for example the International System of Units.
Traceability is particularly crucial that you companies which must abide by 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 keep to the requirements of ISO so that they can claim ISO compliance because of their product. This compliance is commonly an indication of an organization’s resolve for service and/or quality.
NIST Traceable Calibration
From the U.S., NIST may be the legally established National Standards Laboratory. Therefore, NIST gets the responsibility “to develop, maintain and retain custody in the national standards of measurement, and to supply the means and techniques for making measurements in line with those standards; to make sure the compatibility of Usa national measurement standards with those standards; and assure the compatibility of U . s . 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 employed to establish the series of calibrations that successively url to the actual required 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 industry environment is the sole responsibility in the lab performing the calibration work.
