Standards Development

Scope

This part of 81346 International Standard, published jointly by IEC and ISO, provides, in combination with IEC 81346-1 and IEC 81346-2, rules and recommendations on the structuring of systems and the information on systems in area of technical products and equipment of manufacturing systems. It also provides classification scheme of infrastructure objects in such system for use in function - product- location- and type-specific reference designations of technical products and their documentation for manufacturing systems.

The structuring principles and the classes of infrastructure objects are intended to provide a clear identification and localization of the technical products, and for use in their labelling in the manufacturing plant, for their designation in technical documents and for the designation of the technical documents as well.

This document encompasses the process of transforming, processing and maintaining material. The specifications in this document apply for processing, transportation and storage of final products, as well as for auxiliary systems to support the manufacturing process such as electrical systems, management systems and waste disposal systems.This document is not applicable for designations related to product individuals (e.g. inventory number, serial number) or the designation of object types and classes of products (e.g. article number or parts number).

Purpose

This standard considers and supports the planning, design, utilization and maintenance of manufacturing systems. The application of Reference Designation System RDS may lead to restructuring and reorientation of these activities. It offers however chances and potentials of increasing efficiency and economization. Advantages of designation systems, which will be more and more important in the future are:

- The reference designation system can be applied in several technical fields in the same way and is not designed only for one. Mechanical, electrical and process equipment can be treated the same way

– a basis for companywide synergy effects

- The reference designation system allows integrating any kind of systems and components without changing the once defined designations.

- The reference designation is not bound to a fixed structural pattern. Thus, the designation system is expandible, which makes the interpretability in some cases quite complex. Therefore, an exact and computer interpretable documentation and description is essential.

- The application of different aspects allows, for instance, the designation of functions independently from realizing products and their location.

- The different representation of systems through multiple aspects and the relations between these, allows for a more inclusive and complete reference model of systems.

This standard will build upon the already well established classification s tructure of ISO 81346-10 and ISO 81346-12. This will ensure a better understanding and readability of reference designations for users across the construction, power supply and manufacturing industry.
