IEC/CD 81346-8

Industrial systems, installations and equipment and industrial products — Structuring principles and reference designations — Part 8: Properties

Scope

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).
