Metrological traceability refers back to the measurement result which is often related via an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is a basic assurance that the relationship exists involving the measurement link between a measurement instrument as well as the price of a measurement standard. Every one of Tektronix standards are traceable directly to the International System of Measurements (SI), the actual most widely used 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 assists you to reach the accuracy, precision and interchangeability needed for global trade markets. To offer truly standardized components, industry will depend on consistent and reliable measurements that are traceable to some recognized measurement system for example the International System of Units.
Traceability is particularly vital that you businesses that 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 continue with the requirements of ISO in order to claim ISO compliance for his or her product. This compliance is generally a signal of the organization’s dedication to service and/or quality.
NIST Traceable Calibration
Within the U.S., NIST may be the legally established National Standards Laboratory. As such, NIST has the responsibility “to develop, maintain and retain custody in the national standards of measurement, and supply the means and methods in making measurements in keeping with those standards; to assure the compatibility of U . s . national measurement standards with those standards; and to assure the compatibility of United states of america 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 from the SI.
Fundamental to a NIST traceable calibration is thorough documentation in the measurement process utilized to establish the number of calibrations that successively hyperlink to the required reference standard. NIST is responsible just for documenting traceability because of its reference standards as well as the instruments it directly measures. Documenting NIST traceable calibrations in the flooring buisingess environment could be the sole responsibility of the lab performing the calibration work.
