The purpose of this standard is to define requirements for the management of electromagnetic emissions and susceptibility of devices used in the railway so that all systems used in the railway are electromagnetically compatible.These requirements define the minimum effort required to manage the risk associated with EMC and to ensure compliance with legal and regulatory, safety and reliability requirements; particular situations may require more detailed assessment.The scope of this document covers requirements for the management of EMC as applicable to:- a) Planning EMC management- b) Introduction of new rail assets (new products or integrated systems) - c) Alterations to existing rail assets (existing products or integrated systems)- d) Novel alterations to existing rail system configurations or layouts- e) Maintenance of operational rail systems- f) Decommissioning of rail systemsThe scope of this standard is limited to rail systems and assets under the scope and control of the Australian railway networks.
