Full title and description

Industrial systems, installations and equipment and industrial products — Structuring principles and reference designations — Part 10: Power supply systems (ISO 81346-10:2022). This part of the 81346 series (often referred to as RDS‑PS) provides industry-specific rules and guidance for structuring power supply systems and for creating unambiguous reference designations used to identify, label and retrieve information about objects and components in power generation, transmission, distribution and auxiliary power systems.

Abstract

This document is supplementary to the general principles in IEC/ISO 81346‑1 and gives rules and examples for formulating reference designations for objects in the domain of power supply systems. It defines classes for systems and spaces in the power domain, designation blocks and labeling guidance so that components and systems can be consistently identified across documents and life‑cycle stages.

Scope

ISO 81346‑10:2022 applies the general structuring principles of IEC/ISO 81346‑1 specifically to power supply systems. It covers rules for structuring systems and information, formulation of reference designations (RDS) for objects and components, and defines system/space classes used in the power domain (generation, transmission, distribution, storage and auxiliary systems). The standard is intended to be technology‑neutral and usable across different power industries and combinations of technologies.

Key topics and requirements

• Rules for constructing unambiguous reference designations for objects in power supply systems.
• Definition of classes and codes specific to power systems (system and space classes for RDS‑PS).
• Designation blocks and rules for labeling components to link physical items to documentation.
• Guidance for mapping power‑sector structuring to the generic rules of IEC/ISO 81346‑1 and to IEC/ISO 81346‑2 classification codes.
• Examples and application notes showing how to apply RDS in generation, transmission, distribution and storage contexts.
• Recommendations to support consistent information retrieval across drawings, documents and management systems (e.g., CMMS/EAM/PDM integration).
• Compatibility notes for use by standards committees and for creation of national/adopted versions.

Typical use and users

Engineers and system architects in power generation, transmission and distribution; plant/documentation engineers; technical authors and illustrators; asset and maintenance managers; information‑management specialists (EAM/CMMS/PDM tool integrators); procurement and labeling teams; standards bodies and consultants implementing a Reference Designation System for power projects and facilities.

Related standards

Key related documents include IEC/ISO 81346‑1 (Basic rules), IEC/ISO 81346‑2 (Classification of objects and class codes), other 81346 sector parts (for example 81346‑12 for construction), and the earlier ISO/TS 81346‑10:2015 which this edition replaced. The 81346 series is maintained jointly by IEC TC3 and ISO TC10 (joint working group JWG24).

FAQ

Q: What is this standard?

A: ISO 81346‑10:2022 is Part 10 of the ISO/IEC 81346 series that specifies structuring principles and a reference designation system tailored to power supply systems (RDS‑PS), enabling consistent identification and linking of components and documentation in the power domain.

Q: What does it cover?

A: It provides rules for formulating unambiguous reference designations, defines classes for power systems and spaces, specifies designation blocks and gives examples of application across generation, transmission, distribution and auxiliary systems. It is supplementary to the general rules in IEC/ISO 81346‑1.

Q: Who typically uses it?

A: Power system designers, plant engineers, documentation specialists, asset managers, tool vendors (EAM/PDM/CMMS), and standards/consultancy organisations that need consistent identification and information retrieval across documents and systems.

Q: Is it current or superseded?

A: ISO 81346‑10:2022 is the published and current edition released on 1 August 2022 and it replaced ISO/TS 81346‑10:2015. A subsequent working draft (ISO/WD 81346‑10, edition 2) has been recorded as under development at ISO, so users should check with ISO or their national standards body for any newer editions or draft updates before adoption in new projects.

Q: Is it part of a series?

A: Yes — it is part of the ISO/IEC 81346 series (Reference Designation System, RDS). The series includes Part 1 (basic rules), Part 2 (classification), and multiple sector‑specific parts (e.g., Part 10 for power, Part 12 for construction, Part 14 for manufacturing), all intended to work together.

Q: What are the key keywords?

A: Reference designation, RDS, power supply systems, RDS‑PS, structuring principles, classification, designation block, labeling, asset identification.
