ISO 81346-10:2022

Industrial systems, installations and equipment and industrial products - Structuring principles and reference designation - Part 10: Power supply plants

ISO 81346-10:2022 This document provides rules for structuring of systems in the domain of power supply systems, being supplementary to the general principles for the structuring of systems including structuring of information about systems specified in IEC 81346-1.
Based on these principles, rules and guidance are given for the formulation of unambiguous reference designations for objects in any system.
The reference designation identifies objects for the purpose of creation and retrieval of information about an object and, where realized, about its corresponding component.
A reference designation labelled at a component is the key to finding information about that object among different kinds of documents.
The principles are general and are applicable to all technical areas (e.g. mechanical engineering, electrical engineering, construction engineering, process engineering). They can be used for systems based on different technologies or for systems combining several technologies.
This document also defines classes for systems and spaces in the field of power supply systems.

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 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
organizations, 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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/

This document was prepared by Technical Committee ISO/TC 10, Technical product documentation,
Subcommittee SC 10, Process plant documentation, in cooperation with the Technical Committee
IEC/TC 3, Information structures and elements, identification and marking principles, documentation and

This document cancels and replaces ISO/TS 81346-10:2015, which has been technically revised.
The main changes are as follows:
— converted to an International Standard;
— structure adapted to that of IE
