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 really a basic assurance which a relationship exists between the measurement link between a measurement instrument and the valuation on a measurement standard. Most of Tektronix standards are traceable straight to the International System of Measurements (SI), the most in-demand international system of measurement responsible for defining the meter, kilogram, second, ampere, kelvin, mole, and candela.
How Traceability Impacts Global Markets
Traceability of measurement brings about the SI enables us to get the accuracy, precision and interchangeability necessary for global trade markets. To offer truly standardized components, industry depends upon consistent and reliable measurements which are traceable to some recognized measurement system such as the International System of Units.
Traceability is very imperative that you companies which must conform to 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 to enable them to claim ISO compliance for his or her product. This compliance is usually a signal associated with an organization’s persistence for service and/or quality.
NIST Traceable Calibration
Within the U.S., NIST may be the legally established National Standards Laboratory. As such, NIST has got the responsibility “to develop, maintain and retain custody in the national standards of measurement, and to provide the means and techniques in making measurements in step with those standards; to make sure 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 from the seven base units of the SI.
Fundamental to a NIST traceable calibration is thorough documentation from the measurement process employed to establish the compilation of calibrations that successively url to the desired reference standard. NIST is responsible simply for documenting traceability for the reference standards as well as the instruments it directly measures. Documenting NIST traceable calibrations in the industry environment will be the sole responsibility with the lab performing the calibration work.
