G 18:current
A live document containing the current set of all concepts defined in OIML publications. Generated from G 18 Complete — every terminology entry observed across the OIML publication corpus.
Vision: When developing a future SMART Recommendation, specification of a term in Part 1 would retrieve the agreed definition from the agreed vocabulary. G 18:current makes this possible by maintaining a live concept registry.

|---|---|---|---|
| (gross) calorific value | — | amount of heat which would be released by the complete combustion in air of a specified quantity of gas, in such a way that the pressure at which the reaction takes place remains constant, and all the products of combustion are returned to the same specified temperature as that of the reactants, all of these products being in the gaseous state except for water formed by combustion, which is condensed to the liquid state at this specified temperature | 1 |
| (instrumental) drift | — | continuous or incremental change over time in indication, due to changes in the metrological properties of a measuring instrument | 1 |
| (measurement) error | — | measured quantity value minus a reference quantity value | 1 |
| (measurement) standard | VIM | material measure, measuring instrument, reference material or measuring system intended to define, realize, conserve or reproduce a unit or one or more values of a quantity to serve as a reference | 1 |
| (permanent) magnetization | — | parameter that specifies a magnetic state of material bodies such asweights, in the absence of an external magnetic field (most generally, magnetization is a vector whose magnitude and direction are not necessarily constant within the material).
