工业系统、装置、设备和工业产品.结构原理和参考名称.第1部分:基本规则

[中文适用范围]： 本部分国际标准的出版由国际电工委员会（IEC）和国际标准化组织（ISO）联合发布，旨在建立系统结构化的通用原则，包括系统信息的结构化原则。基于这些原则，本标准提供了制定系统中任何对象的无歧义参考设计号的规则和指南。参考设计号用于创建和检索关于对象的信息，并在对象及其相应组件实现后，用于检索关于该组件的信息。在组件上标记的参考设计号是查找有关该对象信息的不同类型文档中的关键。这些原则具有一般性，适用于所有技术领域（例如机械工程、电气工程、建筑工程、过程工程）。它们可用于基于不同技术的系统，也可用于结合多种技术的系统。本文件也是一种水平出版物，供技术委员会在准备有关参考设计号的出版物时使用，遵循国际电工委员会指南108中规定的基本原则。 [外文原描述]： IEC 81346-1:2022 establishes general principles for the structuring of systems including structuring of information about systems. 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 (for example 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 is also a horizontal publication intended for use by technical committees in preparation of publications related to reference designations in accordance with the principles laid down in IEC Guide 108. IEC 81346-1:2022 cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the scope includes a reference to IEC Guide 108 for being a horizontal publication; b) synchronization with IEC 81346-2:2019 and ISO 81346-12:2018; c) the introduction of the type aspect; d) introduction of an information model of the reference designation system; e) introduction of an information model for the framework of reference designation system to comply with International Standard 81346 series; f) introduction of recommendation for metadata for design structure management; g) introduction of rules and method for designation of relations between objects; h) introduction of requirements for development of sector-specific parts of the International Standard 81346 series; i) introduction of requirements for incorporation of sub-object in object structures; j) introduction of recommendations for documentation of the application of the International Standard 81346 series; k) introduced definition of new terms used; l) new rules added and existing rules modified; m) notes related to rules are converted to normative text as "Comment to Rule nn".
