1 Scope
This part of ISO/IEC 1 1 801 specifies generic cabling for use within industrial premises, or industrial areas within other types of premises, which can comprise single or multiple buildings on a campus. It covers balanced cabling and optical fibre cabling. This document is optimized for premises in which the maximum distance over which telecommunications services can be distributed is 1 0 000 m. The principles of this document can be applied to larger installations. Cabling defined by this document supports a wide range of services, including automation, process control, and monitoring applications. That can also incorporate the supply of power. This document specifies directly or via reference to ISO/IEC 1 1 801 -1 a) the structure and minimum configuration for generic cabling within industrial premises, b) the interfaces at the telecommunications outlet (TO), c) the performance requirements for cabling links and channels, d) the implementation requirements and options, e) the performance requirements for cabling components, f) the conformance requirements and verification procedures. The cabling providing critical automation, process control and monitoring applications within the automation islands is not addressed by this document. Information for this application- specific cabling is provided in the IEC 61 784-5 series (design) and in IEC 61 91 8 (installation). Safety (electrical safety and protection, fire, etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of this document, and are covered by other standards and by regulations. However, information given by this document can be of assistance.
3 Terms, definitions, abbreviated terms and symbols
3.1 Terms and definitions For the purposes of this document, the terms and definitions given in ISO/IEC 1 1 801 -1 and the following apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp 3.1 .1 apparatus one or more pieces of equipment having specific and defined overall functions within industrial premises served by one or more network interfaces 3.1 .2 apparatus attachment cord cord used to connect a telecommunications outlet to a network interface 3.1 .3 automation island premises and areas where a combination of systems that control, monitor and protect process(es) of a plant are installed 3.1 .4 automation outlet fixed connecting hardware which provides an interface to the automation island (AI) 3.1 .5 bulkhead wall or barrier which maintains the ingress and climatic environmental classifications applicable on either side 3.1 .6 equipment room room dedicated to housing distributors and application-specific equipment 3.1 .7 floor cable cable connecting the floor distributor to the intermediate distributor 3.1 .8 floor distributor distributor used to make connections between the floor cable, other cabling subsystems and active equipment 3.1 .9 intermediate cable cable connecting the intermediate distributor to the telecommunications outlet 3.1 .1 0 intermediate distributor distributor used to make connections between the intermediate cable, other cabling subsystems and active equipment 3.1 .1 1 industrial intermediate distributor intermediate distributor used to make connections between several automation islands and transmit critical process control, monitoring and automation data (PCMA) between them 3.1 .1 2 network interface interface between the apparatus attachment cabling and the apparatus network 3.1 .1 3 telecommunications room enclosed space for housing telecommunications equipment, cable terminations, interconnect and cross-connect
4 Conformance
For a cabling installation to conform to this document the following applies. a) The configuration and structure shall conform to the requirements outlined in Clause 5. b) Channels shall meet the requirements specified in Clause 6 when subjected to environment conditions, local to the channels (see NOTE below), as defined by the applicable environmental Class(es) of Clause 6. This shall be achieved by one of the following: 1 ) a channel design and implementation ensuring that the prescribed channel performance of Clause 6 is met; 2) attachment of appropriate components to a permanent link or CP link design meeting the prescribed performance class of Clause 7. Channel performance shall be ensured where a channel is created by adding more than one cord to either end of a link meeting the requirements of Clause 7; 3) for E 1 environments, using the reference implementations of Clause 8 and compatible cabling components conforming to the requirements of Clauses 9, 1 0 and 1 1 based upon a statistical approach of performance modelling.
