Ken, I thought I remembered a newer version, so checked the IPC catalog and found........ IPC-9191 is a harmonization of IPC-PC-90 and the International Organization for Standardization (ISO) SPC Guideline 11462-1. ISO 11462-1 has been adopted as the foundation for IPC-9191 and is printed in italicized type. Interpretations and supplemental SPC system requirements, as well as implementation guidelines have been harmonized and printed in normal type. Companies may adopt this document; the IPC retains full control over the content except for ISO 11462-1, of which copyright remains with the ISO. This document is intended to provide information to support the application of process control and related statistical techniques specified in international and industry standards. The ISO 11462-1 sections were prepared by working group 8 of ISO/ITC 69 SC 4.
