Metrological traceability means measurement result which is often related using an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is a basic assurance that a relationship exists involving the measurement connection between a measurement instrument along with the value of a measurement standard. All Tektronix standards are traceable straight away 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 leads to the SI can help you reach the accuracy, precision and interchangeability necessary for global trade markets. To supply truly standardized components, industry depends upon reliable and consistent measurements which can be traceable to a recognized measurement system for example the International System of Units.
Traceability is specially imperative that you businesses that must adhere to or stick 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 stick to the requirements of ISO so that they can claim ISO compliance for their product. This compliance is normally an indication of your organization’s dedication to service and/or quality.
NIST Traceable Calibration
Within the U.S., NIST could be the legally established National Standards Laboratory. Consequently, NIST has the responsibility “to develop, maintain and retain custody from the national standards of measurement, and supply the means and techniques for making measurements in line with those standards; to assure the compatibility of Usa national measurement standards with those standards; also to assure the compatibility of U . s . national measurement standards with that regarding 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 in the measurement process used to establish the compilation of calibrations that successively hyperlink to the desired reference standard. NIST is responsible only for documenting traceability for its reference standards and also 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.
