Division 6.2.1.3 Assessment in migration phases
United Kingdom
Upgrading an existing track-side or on-board Control-Command Assembly may be performed in successive steps in accordance with chapter 7. In each step only compliance with the TSI requirements relevant for the step is achieved, while other requirements of the remaining steps are not fulfilled.
The contracting entity may lodge an application for the assessment of the Assembly at this step from a Notified Body.
Independently of the modules chosen by the contracting entity the Notified Body shall verify that:
-
the TSI requirements relevant for this step are respected
-
the TSI requirements already assessed are not prejudiced
Functions already assessed and unchanged and not affected by this step do not need to be checked again.
The certificate(s) issued by the Notified Body after the positive assessment of the Assembly is accompanied by reservations indicating the limits of the certificate(s), which TSI requirements are fulfilled and which are not fulfilled.
