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 often a basic assurance a relationship exists between your measurement connection between a measurement instrument and also the value of a measurement standard. Every one of Tektronix standards are traceable right to the International System of Measurements (SI), the actual hottest international system of measurement in charge of 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 reach the accuracy, precision and interchangeability required for global trade markets. To deliver truly standardized components, industry depends upon reliable and consistent measurements which are traceable into a recognized measurement system including the International System of Units.
Traceability is specially important to companies which 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 continue with the requirements of ISO in order to claim ISO compliance for product. This compliance is usually a signal of an organization’s persistence for service and/or quality.
NIST Traceable Calibration
Inside the U.S., NIST will be the legally established National Standards Laboratory. Therefore, NIST gets the responsibility “to develop, maintain and retain custody from the national standards of measurement, and to supply the means and techniques for making measurements in line with those standards; in order to guarantee the compatibility of United states of america national measurement standards with those standards; and assure the compatibility of Usa national measurement standards with those of other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations of the seven base units in the SI.
Fundamental to a NIST traceable calibration is thorough documentation in the measurement process accustomed to establish the group of calibrations that successively hyperlink to the actual required reference standard. NIST is responsible only for documenting traceability due to the reference standards as well as the instruments it directly measures. Documenting NIST traceable calibrations in the industry environment is the sole responsibility from the lab performing the calibration work.
