In technical, scientific and engineering work (such as metrology) it is important to correctly use words that have a technical meaning.
Journals and other publications, as well as publications of relevant technical and professional organizations give the intended meaning of the word, so everyone in the business knows what it is. In technical work, only the technical definitions should be used.
This calibration glossary gives you a quick reference to the meaning of common terms, such as:
