Overview
This International Standard specifies terminology, rules and methodology for the indication and understanding of datums and datum systems in technical product documentation. This International Standard also provides explanations to assist the user in understanding the concepts involved. This document defines the specification operator (see ISO 17450-2) used to establish a datum or datum system. The verification operator (see ISO 17450-2) can take different forms (physically or mathematically) and is not the subject of this International Standard. This document has been parpared by ISO/TC 213/WG 2 "Datums and datum systems", in collaboration with CEN/TC 290 "Dimensional and geometrical product specification and verification", the secretariat of which is held by AFNOR (France). On the national level NA 152-03-02 AA "CEN/ISO Geometrische Produktspezifikation und -prüfung" ("CEN/ISO Dimensional and geometrical product specification and verification") of the Fundamental Technical Standards Committee (NATG) at DIN is responsible.
