# 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 3.2.1: SAFETY

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

Every project to which this specification is applicable shall put into effect the measures necessary to demonstrate that the level of risk of an incident occurring that is within the scope of the control-command systems is not higher than the objective required for the service. For this purpose, Annex A, index 1, shall be used.
For class A equipment, the global safety objective for the subsystem is apportioned between the on-board and trackside assemblies. For the safety-related part of one on-board assembly as well as for one trackside assembly, the safety requirement for ETCS level 2 is: tolerable hazard rate of 10-9/hour (for random failures) corresponding to safety integrity level 4 (preliminary value to be confirmed and to be extended for other ETCS levels). The detailed requirements are specified in Annex A, index 2a.
For class B equipment used for high speed operation, it is the responsibility of the Member State to guarantee that appropriate safe speed enforcement is performed by the class B system, and to state the speed limit.
