ISO 7870-5:2014 establishes a guide to the use and understanding of specialized control charts in situations where commonly used Shewhart control chart approach to the methods of statistical control of a process may either be not applicable or less efficient in detecting unnatural patterns of variation of the process.
Abstract
Overview
ISO 7870-5:2014 - Control charts: Part 5, Specialized control charts provides guidance on selecting, using and interpreting specialized control charts where standard Shewhart methods are inadequate or less efficient. The standard helps practitioners apply statistical process control (SPC) techniques in special situations such as widely spaced samples, changing process averages, non-normal data, large sample sizes, or when different types of nonconformities have different criticality. It focuses on practical use - when to choose a specialized chart, how control limits are determined, and the chart’s advantages and limitations.
