Organization: ISO
Publication Date: 15 September 2012
Status: active
Page Count: 54
ICS Code (Application of statistical methods): 03.120.30
scope:

This part of ISO 22514 defines a procedure to validate measuring systems and a measurement process in order to state whether a given measurement process can satisfy the requirements for a specific measurement task with a recommendation of acceptance criteria. The acceptance criteria are defined as a capability figure (CMS) or a capability ratio (QMS).

NOTE 1 This part of ISO 22514 follows the approach taken in ISO/IEC Guide 98-3, Guide to the expression of the uncertainty in measurement (GUM), and establishes a basic, simplified procedure for stating and combining uncertainty components used to estimate a capability index for an actual measurement process.

NOTE 2 This part of ISO 22514 is primarily developed to be used for simple one-dimensional measurement processes, where it is known that the method uncertainty and the specification uncertainty are small compared to the implementation uncertainty. It can also be used in similar cases, where measurements are used to estimate process capability or process performance. It is not suitable for complex geometrical measurement processes, such as surface texture, form, orientation and position measurements that rely on several measurement points or simultaneous measurements in several directions.
