ISO/TC 10/SC 10/JWG 10 - Joint ISO/TC 10/SC 10 - IEC/TC 3 WG: Reference designation system

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.

This document establishes rules for structuring of systems and the formulation of reference designations and provides classes for systems in the field of construction works and building services. This document also specifies a classification of objects and corresponding letter codes for use in reference designations of object occurences. This document is not intended for manufacturers or system-related designations of individuals (e.g. inventory number or serial number) or for product types (e.g. article number or parts number).

ISO/TS 81346-10:2015 contains sector-specific stipulations for structuring principles and reference designation rules on technical products and technical product documentation of power plants. It applies in combination with IEC 81346‑2, ISO/TS 81346‑3, VGB-B 101 and VGB-B 102 for the classification of systems and objects, and for function-, product- and location-specific designation of technical products and their documentation for power plants. It specifies the designation blocks for the clear identification and localization of the technical products, which are used for their labelling in the plant, for their designation in technical documents and for the designation of the technical documents as well. This Technical Specification encompasses the process of energy conversion. The specifications in this document apply for the power plant process, for the primary energy supply and final products distribution, as well as for auxiliary media and auxiliary energy supply, waste materials and waste energy disposal. This Technical Specification is not applicable to recovery of the primary energy and the media for supplying the process, nor to the processing of residues from process disposal (e.g. gypsum, slag products, waste water, etc.).

ISO/TS 81346-3 establishes comprehensive and practice-oriented principles and rules for the designation of technical objects within a system, as well as for the designation of connections, signals and documents in accordance with the corresponding basic standards. The principles of ISO/TS 81346-3 apply to all technical fields for all industries and can be applied in all phases of the life cycle of a technical object. The designation of types, individuals, cost-centres, projects, etc. is not covered.

ISO/TS 16952-10:2008 contains sector-specific stipulations for structuring principles and reference designation rules on technical products and technical product documentation of power plants. It applies in combination with ISO/TS 16952-1, IEC/PAS 62400 and VGB B 101 for the classification of systems and objects, and for function-, product- and location-specific designation of technical products and their documentation for power plants. It specifies the designation blocks for the clear identification and localization of the technical products, which are used for their labelling in the plant, for their designation in technical documents and for the designation of the technical documents as well. ISO/TS 16952-10:2008 encompasses the process of energy conversion. The specifications in ISO/TS 16952-10:2008 apply for the power plant process, for the primary energy supply and final products distribution, as well as for auxiliary media and auxiliary energy supply, waste materials and waste energy disposal. ISO/TS 16952-10:2008 is not applicable to recovery of the primary energy and the media for supplying the process, nor to the processing of residues from process disposal (e.g. gypsum, slag products, waste water, etc.).
