Metrological traceability means measurement result which can be related via an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It can be a basic assurance that a relationship exists relating to the measurement link between a measurement instrument and the price of a measurement standard. All of Tektronix standards are traceable straight away to the International System of Measurements (SI), the hottest 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 leads to the SI makes it possible to attain the accuracy, precision and interchangeability necessary for global trade markets. To offer truly standardized components, industry is dependent upon consistent and reliable measurements that are traceable with a recognized measurement system for example the International System of Units.
Traceability is very important to firms 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 continue with the requirements of ISO in order to claim ISO compliance because of their product. This compliance is generally an indication of the organization’s resolve for service and/or quality.
NIST Traceable Calibration
In the U.S., NIST is the legally established National Standards Laboratory. Therefore, NIST gets the responsibility “to develop, maintain and retain custody in the national standards of measurement, and give you the means and methods in making measurements in keeping with those standards; in order to guarantee the compatibility of Usa national measurement standards with those standards; and assure the compatibility of U . s . 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 of the SI.
Important a NIST traceable calibration is thorough documentation in the measurement process employed to establish the number of calibrations that successively hyperlink to the actual required reference standard. NIST is responsible only for documenting traceability due to the reference standards along with the instruments it directly measures. Documenting NIST traceable calibrations in the commercial environment may be the sole responsibility in the lab performing the calibration work.
