标准范围

ISO 7870-3:2012给出了验收控制图的使用指南，并建立了确定样本大小、行动限制和决策标准的一般程序。只有在以下情况下才应使用该图表:a）子组内的变异得到控制，且变异得到有效估计；b） 已实现高水平的处理能力。当所研究的过程变量为正态分布时，通常使用该图表，但是，它可以应用于非正态分布。举例说明了这种技术的优点，并提供了确定样本量、行动限制和决策标准的细节。

ISO 7870-3:2012 gives guidance on the uses of acceptance control charts and establishes general procedures for determining sample sizes, action limits and decision criteria. This chart should be used only when: a) the within subgroup variation is in-control and the variation is estimated efficiently; b) a high level of process capability has been achieved.This chart is typically used when the process variable under study is normally distributed, however, it can be applied to a non-normal distribution. Examples are included to illustrate a variety of circumstances in which this technique has advantages and to provide details of the determination of the sample size, the action limits and the decision criteria.
