Article 7
1. In the event of a change to a subsystem placed in service without an ‘EC’ declaration of verification, the applicant shall analyse the change and assess the impact on the existing design and maintenance documentation. 2. Where a change is made to a subsystem that affects a basic parameter, the applicant shall assess the need for, and where required carry out the ‘EC’ verification procedure in accordance with Article 15 of Directive (EU) 2016/797. 3. The conformity assessment body shall only assess the parts of the subsystem that are changed, and assess the interfaces to the unchanged parts of the subsystem. 4. An ‘EC’ declaration of verification shall be established by the applicant for the whole subsystem by declaring under its sole responsibility that: (a) the changed part and the interfaces to the unchanged parts of the subsystem have been subject to the relevant verification procedures and comply with the relevant Union law and any relevant national rules. (b) the unchanged part has been brought into use in the railway system and has been maintained in its design operating state since the date of bringing into use in the railway system until the date of the establishment of EC declaration of verification.
