[Superseded]Telecommunications installations - Generic cabling - Industrial premises
Adopts ISO/IEC 24702:2006 to specify generic cabling that supports a wide range of communications services including automation, process control and monitoring applications for use within industrial premises or industrial areas within other types of premises, comprising single or multiple buildings on campus. It covers balanced cabling and optical fibre cabling and is based upon and references the requirements of ISO/IEC 11801.
