Metrological traceability refers to the measurement result which may be related through an unbroken chain of calibrations, including measurement uncertainty determination, to specified references. It is really a basic assurance that the relationship exists between the measurement link between a measurement instrument and the worth of a measurement standard. Most of Tektronix standards are traceable straight away to the International System of Measurements (SI), which is the most favored international system of measurement responsible for defining the meter, kilogram, second, ampere, kelvin, mole, and candela.
How Traceability Impacts Global Markets
Traceability of measurement leads to the SI assists you to get the accuracy, precision and interchangeability needed for global trade markets. To supply truly standardized components, industry will depend on consistent and reliable measurements which can be traceable to a recognized measurement system such as the International System of Units.
Traceability is very important to companies that must abide by 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 follow the requirements of ISO in order to claim ISO compliance because of their product. This compliance is usually a signal of an organization’s persistence for service and/or quality.
NIST Traceable Calibration
From the U.S., NIST is the legally established National Standards Laboratory. Therefore, NIST has got the responsibility “to develop, maintain and retain custody from the national standards of measurement, and to give you the means and techniques to make measurements consistent with those standards; to guarantee the compatibility of U . s . national measurement standards with those standards; also to assure the compatibility of Usa 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 in the SI.
Fundamental to a NIST traceable calibration is thorough documentation with the measurement process utilized to establish the group of calibrations that successively url to the required reference standard. NIST is responsible simply for documenting traceability for the reference standards along with the instruments it directly measures. Documenting NIST traceable calibrations available environment will be the sole responsibility with the lab performing the calibration work.
