14、se from IHS -,-,- ISO 11462-1:2001(E) iv ISO 2001 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO techni
15、cal committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely w
16、ith the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to th
17、e member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 11462 may be the subject of patent rights. ISO shall not be held responsibl
18、e for identifying any or all such patent rights. International Standard ISO 11462-1 was prepared by Technical Committee ISO/TC 69, Applications of statistical methods, Subcommittee SC 4, Applications of statistical methods in process management. ISO 11462 consists of the following parts, under the g
19、eneral title Guidelines for implementation of statistical process control (SPC): Part 1: Elements of SPC A catalogue of tools and techniques will be the future subject of part 2 to ISO 11462.

21、n 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
22、 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 s
23、ervices 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 proce
24、ss 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
