Metrological traceability means 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 your measurement results of a measurement instrument as well as the valuation on a measurement standard. All Tektronix standards are traceable directly to the International System of Measurements (SI), the most widely used 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 makes it possible to attain the accuracy, precision and interchangeability needed for global trade markets. To supply truly standardized components, industry depends upon reliable and consistent measurements which can be traceable with a recognized measurement system including the International System of Units.
Traceability is very important to companies that must adhere to 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 for their product. This compliance is usually an indication of your organization’s resolve for service and/or quality.
NIST Traceable Calibration
Within the U.S., NIST could be the legally established National Standards Laboratory. Therefore, NIST gets the responsibility “to develop, maintain and retain custody with the national standards of measurement, and to provide the means and techniques for making measurements consistent with those standards; in order to guarantee the compatibility of U . s . national measurement standards with those standards; and to assure the compatibility of United States national measurement standards with the ones from other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations in the seven base units in the SI.
Fundamental to a NIST traceable calibration is thorough documentation with the measurement process accustomed to establish the number of calibrations that successively link to the required reference standard. NIST is responsible just for documenting traceability for the reference standards and the instruments it directly measures. Documenting NIST traceable calibrations in the industry environment could be the sole responsibility with the lab performing the calibration work.
