Metrological traceability refers back to the measurement result which may be related via an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It can be a basic assurance a relationship exists between your measurement results of a measurement instrument and also the valuation on a measurement standard. Most of Tektronix standards are traceable right to the International System of Measurements (SI), the most in-demand international system of measurement accountable for defining the meter, kilogram, second, ampere, kelvin, mole, and candela.
How Traceability Impacts Global Markets
Traceability of measurement results in the SI assists you to achieve the accuracy, precision and interchangeability essential for global trade markets. To supply truly standardized components, industry is determined by reliable and consistent measurements which are traceable to a recognized measurement system for example the International System of Units.
Traceability is very vital that you companies that must abide by or keep 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 continue with the requirements of ISO so that they can claim ISO compliance for their product. This compliance is normally an illustration of the organization’s resolve for service and/or quality.
NIST Traceable Calibration
In the U.S., NIST will be the legally established National Standards Laboratory. Therefore, NIST contains the responsibility “to develop, maintain and retain custody from the national standards of measurement, and provide you with the means and methods in making measurements in keeping with those standards; to assure the compatibility of United states of america national measurement standards with those standards; also to assure the compatibility of Usa national measurement standards with that relating to 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 employed to establish the number of calibrations that successively hyperlink to the actual required reference standard. NIST is responsible only for documenting traceability because of its reference standards along with the instruments it directly measures. Documenting NIST traceable calibrations available environment may be the sole responsibility with the lab performing the calibration work.
