Metrological traceability means measurement result that may be related using an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It can be a basic assurance a relationship exists involving the measurement results of a measurement instrument and also the valuation on a measurement standard. Most of Tektronix standards are traceable directly to the International System of Measurements (SI), the hottest 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 can help you achieve the accuracy, precision and interchangeability essential for global trade markets. To provide truly standardized components, industry will depend on reliable and consistent measurements which are traceable to some recognized measurement system like the International System of Units.
Traceability is particularly crucial that you businesses that must conform to 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 stick to the requirements of ISO to enable them to claim ISO compliance for product. This compliance is normally an indication associated with an organization’s resolve for service and/or quality.
NIST Traceable Calibration
Within the U.S., NIST will be the legally established National Standards Laboratory. As a result, NIST has the responsibility “to develop, maintain and retain custody with the national standards of measurement, also to supply the means and techniques for making measurements in keeping with those standards; in order to guarantee the compatibility of United States national measurement standards with those standards; and also to assure the compatibility of United States national measurement standards with the ones from other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations with the seven base units in the SI.
Fundamental to a NIST traceable calibration is thorough documentation of the measurement process utilized to establish the number of calibrations that successively link to the desired reference standard. NIST is responsible just for documenting traceability for the reference standards as well as the instruments it directly measures. Documenting NIST traceable calibrations in the commercial environment is the sole responsibility in the lab performing the calibration work.
