Introduction

ISO 11462 provides guidelines for the implementation of a statistical process control (SPC) system. These guidelines are aimed primarily at increasing production efficiency and inherent capability, and reducing interval and cost.

This part of ISO 11462 provides elements to guide an organization in planning, developing, executing, and/or evaluating a statistical process control system. By implementing those elements deemed applicable and appropriate by customer and supplier, an organization may satisfy a requirement to adopt a comprehensive and effective SPC system. By also deploying a quality system with the aim of ensuring that products and services meet customer requirements (such as the system defined by ISO 9001), an organization can improve the infrastructure so as to help hold the gains from its SPC system.

This part of ISO 11462 extends the definition of process control to integrate the traditional definitions of statistical process control, algorithmic process control, and model-based control methods. These are different approaches with the same purpose of reducing variation in both products and processes.

This part of ISO 11462 also extends the definition and usage of the term parameter to apply to a process parameter or a product parameter; and to recognize that a product parameter can be either an in-process product parameter or a final-product parameter. Under specified conditions of measurement, a product parameter can be equivalent to a product characteristic.

Some considerations given in the formulations of ISO 11462 are the following:

a) Elements of part 1 of ISO 11462 guide an organization in how to implement an SPC system. Specific tools and techniques that experience has shown useful in applying these elements within processes will be listed in part 2 of ISO 11462.
b) Users of ISO 11462 should be aware that the use of “should” throughout both parts of ISO 11462 indicates that
1. 1) among several possibilities, one or more are recommended as being particularly suitable and effective, without mentioning or excluding others;
2. 2) a certain course of action is preferred but not necessarily required for a process in order to gain the economic control of production.
This choice of language does not indicate requirements which are to be strictly followed in order to conform to this International Standard and from which no deviation is permitted.
