Standards Development
This part of the 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 classification of properties related to systems designated by reference designations in any area of technical products and equipment. It provides a classification scheme of properties representing characteristics of objects and systems being designated by function- product- location- or type-specific reference designations.
The classes of properties are intended, when combined with a reference designation to provide a clear identification of any property.
RDS 81346-8 Properties are based on fundamental quantities and units in accordance with ISO 80000 standard series and standard data element types in accordance with IEC 61360 standard series (CDD) where applicable. This NP is coordinated with IEC SC3D (CDD) which supports this NP.
This document will provide a generic set of properties which is fit for purpose in the design phase of systems and make these properties an important relation to the object occurrence (see IEC 81346-1, 4.9) as distinct from object individuals (see IEC 81346-1, 4.9).
The ISO/IEC 81346 standard series (known as “RDS” for Reference Designation System) provides the rules and tables for creating a reference model for systems, which is a naming convention for systems used so anyone (humans, tools, documents etc.) can refer to the same object in an unambiguous manner from anywhere, across any platform.
The 81346 standard series has during the last years developed to be significant in the aim for digitalization. The reference designation system enables users to create a “neutral” reference model for all engineering disciplines, which is referrable to/from other systems (e.g. diagramming, 3D, asset management tools etc.) without conflicting with them.
It is also clear that the 81346 standard series supports systems engineering as defined in ISO 15288 and system architecture as defined in ISO 42010, because systems and system breakdowns in different aspects as defined by 81346 is a fundamental part of a system architecture. The 81346 standard series supports the planning, design, utilization and maintenance of system in a wide range of industry domains. Advantages of designation systems in combination with properties, 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. Aeronautics, mechanical, electrical and process equipment can be treated the same way which is a basis for companywide synergy effects.
- The reference designation system allows integrating any kind of systems and components without changing the once defined designations.
- Properties of any system designated by the reference designation system also becomes unambiguous and thereby referrable from other sources.
- Properties are regarded as an important part of digitalization of requirements related to systems and system elements.
- The application of different aspects allows, for instance, the designation of functions independently from realizing products and their location. Properties (in accordance with this proposal) can be related to any of these aspects.
