TS EN ISO 10360-1/AC

TS EN ISO 10360-1/AC is a corrigendum related to the vocabulary part of the acceptance and reverification test series for coordinate measuring machines (CMMs). In the GPS framework, this kind of terminology document helps establish a common language for the performance assessment of CMMs, so that users, laboratories and manufacturers interpret core terms in the same way. The distinction between acceptance testing and reverification is especially important in metrology because it affects how machine performance is discussed, recorded and compared.

Why CMM terminology matters

A coordinate measuring machine determines the three-dimensional coordinates of points on a workpiece and uses them to derive dimensions, form, location and orientation. In this field, terms such as error, uncertainty, measuring volume, datum system and probe behaviour may sound familiar, but they do not mean the same thing in every technical context. A vocabulary standard reduces ambiguity by fixing the meaning of the words used around CMM acceptance and reverification, which is essential for consistent communication across inspection rooms, production environments and calibration settings.

Technical context for this document

In general technical terms, CMMs are high-precision metrology instruments that may use tactile probes or non-contact sensors. Their performance is influenced not only by structural geometry, but also by environmental conditions, probing systems, control software and the measurement strategy applied. A vocabulary-focused part supports this field by aligning the terminology used in related test documents and user procedures. As a corrigendum, this listing supports the parent subject area but does not itself establish the full test method, numerical limits or complete requirements of the base standard.
