Metrological traceability means measurement result which may be related with 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 results of a measurement instrument and the price of a measurement standard. Every one of Tektronix standards are traceable right to the International System of Measurements (SI), the most widely used international system of measurement responsible for defining the meter, kilogram, second, ampere, kelvin, mole, and candela.
How Traceability Impacts Global Markets
Traceability of measurement leads to the SI can help you attain the accuracy, precision and interchangeability needed for global trade markets. To provide truly standardized components, industry is dependent upon reliable and consistent measurements which might be traceable to some recognized measurement system like the International System of Units.
Traceability is especially vital that you firms that must abide by or stick 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 follow the requirements of ISO to enable them to claim ISO compliance for his or her product. This compliance is generally an illustration of your organization’s commitment to service and/or quality.
NIST Traceable Calibration
Inside the U.S., NIST could 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, and provide the means and methods to make measurements in line with those standards; to assure the compatibility of U . s . national measurement standards with those standards; also to assure the compatibility of United States national measurement standards with that relating to other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations from the seven base units with the SI.
Fundamental to a NIST traceable calibration is thorough documentation of the measurement process employed to establish the group of calibrations that successively url to the actual required 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 industry environment could be the sole responsibility from the lab performing the calibration work.
