Scope
This document specifies the validation procedures for measurement systems and measurement processes, used to determine whether a given measurement process can meet the requirements of a specific measurement task. This determination is achieved by comparing the defined capability indices (C MS, C MP) or capability ratios (Q MS, Q MP) with the acceptance criteria. Note: This document follows the technical approach of GB/T 27418 and establishes a basic simplified procedure for evaluating the capability indices of actual measurement processes, covering the expression and synthesis methods of uncertainty components. This document is primarily applicable to simple one-dimensional measurement processes, and requires that both the method uncertainty and the specification uncertainty be smaller than the measurement uncertainty of the measurement equipment. It is also applicable to similar situations where the process capability or process performance is evaluated through measurement. This document is not applicable to complex geometric measurement processes, such as those that rely on multiple measurement points or the simultaneous measurement of surface structure texture and position in multiple directions.
