T
Transfer standard Standard used as an intermediary to compare standards. |
Travelling standard See Standard, travelling. |
True value (of a quantity) The indefinite form rather than the definite form is used in connection with true value, in that there can be many values that are consistent with the definition of a particular quantity. |
U
Uncertainty of measurement Parameter, associated with the result of a measurement that characterises the dispersion of values that could reasonably be attributed to the measurand. The estimation of uncertainty in accordance with GUM guidelines is usually accepted. |
Unit (of measurement) Particular quantity, defined and adopted by convention, with which other quantities of the same kind are compared in order to express their magnitudes relative to that quantity. |
Unit of measurement (derived) coherent Derived unit of measurement that can be expressed as the product of basic units in powers with the proportionality coefficient 1. |
V
Value (of a measurand), transformed Value of a measuring signal that represents a given measurand. |
Value (of a quantity) Magnitude of a particular quantity generally expressed as a unit of measurement multiplied by number. |
Value, nominal Rounded or approximate value of a characteristic of a measuring instrument that provides a guide to its use. |
Values, derived Conditions for use intended to keep the metrological characteristics of a measuring instrument specified limits. |
