# Commission Decision of 30 May 2002 concerning the technical specification for interoperability relating to the control-command and signalling subsystem of the trans-European high-speed rail system referred to in Article 6(1) of Council Directive 96/48/EC (notified under document number C(2002) 1947) (Text with EEA relevance) (2002/731/EC), Division 3.2.5.1.2: Electromagnetic compatibility

Extent: E+W+S+N.I.

The electromagnetic compatibility requirements (which include train detection requirements) are:
(a) internal control-command compatibility
On-board and trackside control-command assemblies shall not interfere with each other.
Class A and class B systems shall not interfere with each other.
(b) Compatibility between the control-command subsystem and other TSI subsystems.
Class A control-command equipment shall not interfere with other TSI subsystems, nor be interfered with by other TSI subsystems.
Neither the train operators nor the infrastructure controllers may install new systems which are not compatible with class A control-command equipment emissions and susceptibility.
(c) Compatibility between the railway and systems external to the trans-European high-speed network
This TSI does not introduce any requirements additional to those specified by applicable European regulations.
The following standards shall be applied:
Annex A, index 4a (emission and susceptibility limits of control-command electronic equipment),
Annex A, index 4b (immunity characteristics of train detection systems),
Annex A, indices 12a and 12b (emission and susceptibility limits of balise and loop interfaces),
Annex A, index 12c (emission and susceptibility limits of train radio interfaces).
