A railway is a complex distributed engineering system: the construction of a new railway or the modernisation of a existing one requires a deep understanding of the constitutive components and their interaction, inside the system itself and towards the outside world. The former covers the various subsystems (featuring a complex mix of high power sources, sensitive safety critical systems, intentional transmitters, etc.) and their interaction, including the specific functions and their relevance to safety. The latter represents all the additional possible external victims and sources of electromagnetic interaction. EMC thus starts from a comprehension of the emissions and immunity characteristics and the interactions between sources and victims, with a strong relationship to electromagnetics and to system modeling. On the other hand, the said functions are achieved and preserved and their relevance for safety is adequately handled, if the related requirements are well posed and managed throughout the process from the beginning. The link is represented by standards and their correct application, as a support to analysis, testing and demonstration.

This Part of GB/T 24338 specifies the structure and content of other parts of GB/T 24338. This Part specifies performance criteria which apply to the whole standard. Chapter 5 gives information on electromagnetic compatibility management. The use of this Part alone is insufficient to judge whether the basic requirements of the electromagnetic compatibility specification are met. It shall be considered in conjunction with other parts of GB/T 24338.
