Metrological traceability refers back to the measurement result which may be related using an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is a basic assurance that the relationship exists between the measurement results of a measurement instrument as well as the price of a measurement standard. Most of Tektronix standards are traceable straight to the International System of Measurements (SI), the actual most in-demand 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 leads to the SI enables us to achieve the accuracy, precision and interchangeability necessary for global trade markets. To deliver truly standardized components, industry will depend on consistent and reliable measurements that are traceable with a recognized measurement system for example the International System of Units.
Traceability is specially important to companies that must comply with or follow 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 so that they can claim ISO compliance for product. This compliance is generally an indication associated with an organization’s commitment to service and/or quality.
NIST Traceable Calibration
From the U.S., NIST may be the legally established National Standards Laboratory. Therefore, NIST has got the responsibility “to develop, maintain and retain custody of the national standards of measurement, and provide you with the means and methods to create measurements consistent with those standards; to assure the compatibility of United States national measurement standards with those standards; and assure the compatibility of United States national measurement standards with that regarding other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations in the seven base units of the SI.
Fundamental to a NIST traceable calibration is thorough documentation of the measurement process accustomed to establish the number of calibrations that successively url to the required reference standard. NIST is responsible simply for documenting traceability for its reference standards along with the instruments it directly measures. Documenting NIST traceable calibrations in the flooring buisingess environment will be the sole responsibility in the lab performing the calibration work.
