# Commission Decision of 7 November 2006 concerning a technical specification for interoperability relating to the control-command and signalling subsystem of the trans-European high speed rail system and modifying Annex A to Decision 2006/679/EC concerning the technical specification for interoperability relating to the control-command and signalling subsystem of the trans-European conventional rail system (notified under document number C(2006) 5211) (Text with EEA relevance) (2006/860/EC), Division 6.2.2.3.1: On-Board Assembly Validation

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

For an On-board Assembly the validation under full operational conditions shall be a type test. It is acceptable to be performed on a single instance of the assembly, and shall be performed by means of test runs with the scope to verify:
Performances of the odometry functions.
Compatibility of the Control-Command Assembly with rolling stock equipment and environment (e.g., EMC) in order to be able to multiply the implementation of the On-board Assembly on other locomotives of the same type.
Compatibility of the rolling stock with Control Command Track-side Assembly (e.g EMC aspects, operation of track circuits and axle counters).
Such test runs shall be performed on an infrastructure allowing for verifications in conditions representative of the characteristics that may be found in the trans-European high-speed rail network (e.g., gradients, train speed, vibrations, traction power, temperature).
In case there are limitations to a general applicability of the results of the tests (e.g. TSI compliance proven only up to a certain speed), these limitations shall be recorded in the certificate.
