The property of a result of a measurement whereby it can be related to appropriate standards, generally international or national standards, through an unbroken chain of comparisons all having stated uncertainties
The step-by-step transfer process by which the scale calibration can be related back to primary standards.
(Traçabilité) Records monitoring procedure (audit trail) that is sufficient to determine origin, transfer of ownership and transportation process (i.e. supply chain) for all products labelled as organic or containing organic ingredients.
the transfer process, step by step, by which the load cell's calibration can be correlated to primary standards
The ability to relate individual measurement results through an unbroken chain of calibrations to one or more of the following: U.S. national standard maintained by the National Institute of Standards and Technology (NIST) and/or the US Naval Observatory; Fundamental or natural physical constants with values assigned or accepted by the NIST (i.e., the refractive index of distilled water at 20°C, at a wavelength of 589 nm, is equal to 1.3330 refractive index [nD]); National standards of other countries which are correlated with U.S. national standards; Ratio type calibrations; Comparison to consensus standards.
The ability to trace the history, application or location of a product and, in some cases, service by means of recorded identifications. Traceability may refer to: a product, a calibration and its relationship to the measuring equipment and the national or international standards, primary standards, basic physical constants, properties or references materials. Traceability requirements should be specified for some stated period of history or to some point of origin.
Property of the result of a measurement or the value of a standard whereby it can be related to stated references, usually through an unbroken chain of comparisons, all having stated uncertainties.
Traceability infers that the time standard used on the time-stamp server was set using time directly or indirectly from a National Measurement Institute.
The ability to trace certain products throughout the production and distribution chains facilitating quality control and also the possibility to withdraw products
As defined in the International Vocabulary of Basic and General Terms in Metrology means, "The property of the result of a measure or the value of a standard whereby it relates to references, usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties" (NIST Calibration Services, 2001). Another authoritative source, the ANSI/NCSL A540-1-1994, defines traceability as: "The property of a result of a measurement whereby it can be related to appropriate standards generally national or international standards, through an unbroken chain of comparisons" (NIST Calibration Services, 2001).
Documentation to establish that standards are known in relationship to successively higher standards, culminating with the National Institute of Standards & Technology, or equal.
The pathway (lineage) back to the true value. The relationship between a measured value and an established element of the National/International Measurement System. Also the basis for establishing the true value of a standard. For traceability to exist, there must be an unbroken chain of comparisons between the sample and the National/International Measurement System. Elements of the National/International Measurement System can be fundamental units of measurements (i.e. weight, temperature, pressure) or secondary/transfer standards (i.e. synthetic gas standards).
An unbroken chain of measurements to recognized national and international standards or physical constants, including a stated uncertainty for each measurement step.
To have origins; be traceable - the 'pedigree' of a calibration.
The ability to relate individual measurement results, through a contiguous sequence of measurement accuracy verifications, to nationally or internationally accepted measurement systems (e.g. NIST, ISO, quantum mechanical standards).
the ability to trace a reported measurement through an unbroken chain of comparisons to a national or international standard.
A cornerstone of the National ITS Architecture is the traceability between its components. Microsoft Access databases are used to maintain these connections. The hyperlinked National ITS Architecture relies on this traceability to build the links that allows traversal between user services, logical architecture, and physical architecture.
