Metrological traceability means measurement result that may be related using an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is really a basic assurance which a relationship exists between the measurement connection between a measurement instrument as well as the value of a measurement standard. All of Tektronix standards are traceable right to the International System of Measurements (SI), which is the hottest 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 results to the SI can help you get the accuracy, precision and interchangeability needed for global trade markets. To offer truly standardized components, industry is determined by reliable and consistent measurements that are traceable into a recognized measurement system such as the International System of Units.
Traceability is particularly imperative that you businesses that must comply with 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 follow the requirements of ISO to enable them to claim ISO compliance for product. This compliance is generally an indication of your organization’s dedication to service and/or quality.
NIST Traceable Calibration
Within the U.S., NIST may be the legally established National Standards Laboratory. Consequently, NIST has got the responsibility “to develop, maintain and retain custody of the national standards of measurement, also to provide you with the means and techniques to create measurements consistent with those standards; to make sure the compatibility of U . s . national measurement standards with those standards; and also to 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 of the seven base units in the SI.
Fundamental to a NIST traceable calibration is thorough documentation with the measurement process accustomed to establish the group of calibrations that successively connect to the desired reference standard. NIST is responsible simply for documenting traceability for its reference standards and the instruments it directly measures. Documenting NIST traceable calibrations in the flooring buisingess environment may be the sole responsibility with the lab performing the calibration work.
