ISO 15531-42 : 2005 (E)
Foreword
The International Organisation for Standardisation (ISO) is a worldwide federation of national
standards bodies (ISO member bodies). The work of preparing International Standards is normally
carried out through ISO technical 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 organisations, governmental and non-governmental, in liaison with ISO, also take part in
the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in ISO/IEC Directives, Part 2.
Draft International Standards (DIS) adopted by technical committees are circulated to the 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 15531 may be the
subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

This part of ISO 15531 was prepared by the Technical committee ISO/TC 184 Industrial automation
systems and integration, Sub-Committee 4 Industrial data.

A complete list of parts of ISO 15531 is available from the Internet.
