This part of ISO/IEC 11801 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 10 000 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 11801-1

  1. the structure and minimum configuration for generic cabling within industrial premises,

  2. the interfaces at the telecommunications outlet (TO),

  3. the performance requirements for cabling links and channels,

  4. the implementation requirements and options,

  5. the performance requirements for cabling components,

  6. 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 61784-5 series (design) and in IEC 61918 (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.
