过程管理中的统计方法能力和性能第7部分:测量过程的能力

[中文适用范围]： 本文件定义了验证测量系统和测量过程的程序，以说明给定的测量过程是否可以满足特定测量任务的要求以及验收标准的建议。 验收标准定义为能力数字（CMS、CMP）或能力比率（QMS、QMP）。 注：本文件遵循 ISO/IEC 指南 98-3 (GUM) 中采用的方法，并建立了一个基本的、简化的程序，用于说明和组合用于估计实际测量过程的能力指数的不确定性分量。 本文件主要是为了用于简单的一维测量过程而开发的，众所周知，与实现不确定性相比，方法不确定性和规范不确定性很小。 它还可以用于类似的情况，其中测量用于估计过程能力或过程性能。 它不适合复杂的几何测量过程，例如依赖于多个测量点或多个方向同时测量的表面纹理和位置测量。 [外文原描述]： This document 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 ( C MS , C MP ) or a capability ratio ( Q MS , Q MP ). NOTE This document follows the approach taken in ISO/IEC Guide 98-3 (GUM), and establishes a basic, simplified procedure for stating and combining uncertainty components used to estimate a capability index for an actual measurement process. This document 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 and position measurements that rely on several measurement points or simultaneous measurements in several directions.
