Abstract

In spite of the fundamental importance of the concept ‘measurement’ in the description of our world, there is found an amazing number of very different definitions, even in publications from ISO and IEC, both regarding terminography and selection of characteristics. Of special interest are the choices between relations to single true values or a distribution, inclusion of nominal properties or not, and whether ‘measurement’ is a process or an outcome. These problems should be settled before the production of the fourth edition of the International vocabulary of metrology (VIM), and different possible generic concept diagrams are being discussed.
