工业通讯网络.工业建筑物中通信网络的安装

[中文适用范围]： 本国际标准规定了工业场所以及工业场所自动化岛内部和之间通信网络介质安装的基本要求。该标准涵盖平衡布线和光纤布线。它还涵盖无线媒体的布线基础设施，但不包括无线媒体本身。 IEC 61784-5 系列涵盖了其他介质。该标准是工业自动化岛通信网络，特别是IEC 61158系列和IEC 61784系列中指定的通信网络的配套标准。此外，该标准还涵盖： ?按照 ISO/IEC 24702 的规定为工业场所安装通用电信布线； ？ ISO/IEC 24702 中规定的通用电信布线与自动化岛的特定通信布线之间的连接，其中自动化插座 (AO) 取代了 ISO/IEC 24702 中的电信插座 (TO)。 注：如果在自动化岛中使用的接口AO 不符合 ISO/IEC 24702 TO 的规定，布线不再符合 ISO/IEC 24702，尽管可以保留通用布线的某些功能（包括性能）。该标准提供了应对工业自动化领域关键方面（安全、安保和环境方面，如机械、液体、颗粒物、气候、化学品和电磁干扰）的指南。该标准不承认通过 IEEE 802.3 和 IEEE 802.3at 中未指定的以太网平衡布线系统实现配电。本标准涉及规划人员、安装人员、验证人员、验收测试人员、管理和维护人员的角色，并规定了相关职责和/或提供指导。 [外文原描述]： IEC 61918:2010 specifies basic requirements for the installation of media for communication networks in industrial premises and within and between the automation islands, of industrial sites. It covers balanced and optical fibre cabling and the cabling infrastructure for wireless media, but not the wireless media itself. Additional media are covered in the IEC 61784-5 series. It also covers: - the installation of generic telecommunication cabling for industrial premises as specified in ISO/IEC 24702; - the connection between the generic telecommunications cabling specified in ISO/IEC 24702 - and the specific communication cabling of an automation island, where an automation outlet (AO) replaces the telecommunication outlet (TO) of ISO/IEC 24702. This second edition cancels and replaces the first edition published in 2007 and Corrigendum 1 (2009). It constitutes a technical revision. This edition includes the following technical changes with respect to the previous edition: - 4.4.7.2.1 is updated; - 4.4.7.3.4 is updated; - 5.7.4.3 is updated as result of the revision of the installation profiles; - 6.2.3.1 is updated; - Figure 2, Figure 15, Table 14 and Table B.3 are updated; - a new Figure 35 is added; - a new Table 10 is added; - Annex D is extended to cover additional communication profile families; - Annex F is extended to cover conductor sizes in electrical cables; - Annex H is made normative; - some common requirements are extended as result of the revision of the installation profiles. This bilingual version (2012-05) corresponds to the monolingual English version, published in 2010-07. This publication is to be read in conjunction with ISO/IEC 14763-2:2012 .
