Metrological traceability means measurement result that 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 relating to the measurement results of a measurement instrument along with the value of a measurement standard. All Tektronix standards are traceable right to the International System of Measurements (SI), the actual most favored 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 results in the SI assists you to reach the accuracy, precision and interchangeability necessary for global trade markets. To supply truly standardized components, industry is determined by consistent and reliable measurements that are traceable into a recognized measurement system including the International System of Units.
Traceability is particularly vital that you 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 to be able to claim ISO compliance for their product. This compliance is usually a sign of an organization’s resolve for service and/or quality.
NIST Traceable Calibration
From the U.S., NIST is the legally established National Standards Laboratory. As such, NIST contains the responsibility “to develop, maintain and retain custody in the national standards of measurement, and to supply the means and techniques for making measurements in keeping with those standards; to guarantee the compatibility of Usa national measurement standards with those standards; and assure the compatibility of U . s . national measurement standards with those of other nations.” [15 U.S.C. 271] NIST ensures the U.S. national standards are accurate realizations of the seven base units with the SI.
Fundamental to a NIST traceable calibration is thorough documentation from the measurement process accustomed to establish the number of calibrations that successively hyperlink to the actual required reference standard. NIST is responsible just for documenting traceability because of its reference standards as well as the instruments it directly measures. Documenting NIST traceable calibrations in the industry environment is the sole responsibility with the lab performing the calibration work.
